  • Page 16: Theory

    THEORY 6 .1 DESCRIPTION OF AC MOTOR OPERATION Three phase AC motors are comprised of two major components, the stator and the rotor . The stator is a set of three electrical windings held stationary in the motor housing . The rotor is a metal cylinder, fixed to the motor drive shaft, which rotates within the stator . The arrangement of the stator coils and the presence of three phase AC voltage give rise to a rotating magnetic field which drives the rotor . The speed at which the magnetic field rotates is known as the synchronous speed of the motor . Synchronous speed is a function of the frequency at which the voltage is alternating and the number of poles in the stator windings . The following equation gives the relation between synchronous speed, frequency, and the number of poles: Ss = 120 f/p Where: Ss = Synchronous speed (rpm) f = frequency (Hz) p = number of poles In three phase induction motors the actual shaft speed differs from the synchronous speed as load is applied . This difference is known as “slip” . Slip is commonly expressed as a percentage of synchronous speed . A typical value is three percent at full load . The strength of the magnetic field in the gap between the rotor and stator is proportional to the amplitude of the voltage at a given frequency . The output torque capability of the motor is, therefore, a function of the applied voltage amplitude at a given frequency . When operated below base (rated) speed, AC motors run in the range of “constant torque”...
  • Page 17 CONSTANT TORQUE CONSTANT HP TORQUE HORSEPOWER FREQUENCY (Hz) 6 .1 .1 VARIABLE TORQUE VS . CONSTANT TORQUE Variable frequency drives, and the loads they are applied to, can generally be divided into two groups: constant torque and variable torque . Constant torque loads include: vibrating conveyors, punch presses, rock crushers, machine tools, and just about every other application that is not considered variable torque . Variable torque loads include centrifugal pumps and fans, which make up the majority of HVAC applications . Variable torque loads are governed by the affinity laws, which define the relationships between speed, flow, torque and horsepower . The diagram below illustrates these relationships: 100% 100%...
  • Page 18: Drive Function Description

    “Variable torque” refers to the fact that the torque required varies with the square of the speed . Also, the horsepower required varies with the cube of the speed, resulting in a large reduction in horsepower for even a small reduction in speed . It is easily seen that substantial energy savings can be achieved by reducing the speed of a fan or pump . For example, reducing the speed to 50% results in a 50 HP motor having to produce only 12 .5% of rated horsepower, or 6 .25 HP . Variable torque drives usually have a low overload capacity (110% - 120% for 60 seconds), because variable torque applications rarely experience overload conditions . To optimize efficiency and energy savings, variable torque drives are usually programmed to follow a variable V/Hz ratio . The term “constant torque” is not entirely accurate in terms of the actual torque required for an application . Many constant torque applications have reciprocating loads, such as vibrating conveyors and punch presses, where the rotational motion of the motor is being converted to a linear motion . In such cases, the torque required can vary greatly at different points in the cycle . For constant torque loads, this fluctuation in torque is not a direct function of speed, as it is with a variable torque load . As a result, constant torque drives typically have a high overload rating (150% for 60 seconds) in order to handle the higher peak torque demands . To achieve maximum torque, constant torque drives follow a constant V/Hz ratio .

  • Page 26: Initial Power Up

    INITIAL POWER UP WARNING! Hazard of electrical shock! Disconnect incoming power and wait three minutes before servicing the drive . Capacitors retain charge after power is removed . Before attempting to operate the drive, motor, and driven equipment be sure all procedures pertaining to installation and wiring have been properly followed . WARNING! Severe damage to the drive can result if it is operated after a long period of storage or inactivity without reforming the DC bus capacitors! If input power has not been applied to the drive for a period of time exceeding three years (due to storage, etc), the electrolytic DC bus capacitors within the drive can change internally, resulting in excessive leakage current . This can result in premature failure of the capacitors if the drive is operated after such a long period of inactivity or storage . In order to reform the capacitors and prepare the drive for operation after a long period of inactivity, apply input power to the drive for 8 hours prior to actually operating the drive/motor system .
  • Page 27 If the drive powers up correctly, follow the procedure given below to check the motor rotation: 1 . Verify that there is a wire jumper between terminals TB-1 and TB-2 on the Main Control Board . The drive should have this jumper from the factory . If it is not present, add one, otherwise the drive will not start . 2 . Use the  key to decrease the speed setpoint to the minimum value allowed (0 .50 Hz if Parameter 10 - MIN FRQ has not been changed) . 3 . Press the START key . The drive should indicate RUN, but if the speed setpoint is 0 .50 Hz, the motor may not rotate . Press the  key to increase the speed setpoint until the motor starts to rotate . 4 .

  • Page 48: Description Of Parameters

    DESCRIPTION OF PARAMETERS LINE VOLTS (LINE VOLTAGE) This parameter calibrates the drive for the correct input voltage, and can be set to AUTO, HIGH, or LOW . When set to AUTO, the drive measures the DC bus voltage when power is applied and automatically calibrates itself according to the measured value (DC bus voltage is equal to input voltage multiplied by 1 .4) . This parameter can also be set “manually”, using the HIGH or LOW settings . For actual line voltages of 220 - 240 Vac (on 240/200 Vac models), 460 - 480 Vac (on 480/400 Vac models), or 575 - 600 Vac (on 590/480 Vac models), set this parameter to HIGH . Also use the HIGH setting for 240/120 Vac single-phase input models . Refer to the table below . For actual line voltages of 200 - 208 Vac (on 240/200 Vac models), 380 - 415 Vac (on 480/400 Vac models), or 460 - 480 Vac (on 590 Vac models), set this parameter to LOW . Refer to the table below .

  • Page 50 NOTE The ability to accelerate a given load at a particular rate is limited by the output power capability of the drive/motor combination . The acceleration of high-inertia and high-friction loads may be affected by the current limiting characteristics of the drive . Refer to Parameters: 16 - CURRENT, 19 - FX BOOST, and 20 - AC BOOST for more information . DECEL (DECELERATION TIME) DECEL sets the deceleration rate for all speed reference sources . The DECEL setting is the time to decelerate from BASE FREQUENCY to 0 Hz . As with Parameter 8 - ACCEL, this is a linear function . If the drive is set to coast to a stop, DECEL will have no effect when a STOP command is given . The range of adjustment for DECEL depends on horsepower, voltage, and whether Dynamic Braking (DB) is being used . Refer to the table below: DECELERATION LIMITS HORSEPOWER / VOLTAGE RATING...
  • Page 51 MIN FRQ (MINIMUM FREQUENCY) This parameter defines the lower limit of the drive’s speed range . MIN FRQ is used in conjunction with MAX FRQ (Parameter 11 below) to define the operating range of the drive . If MIN FRQ is set to a value above 0 .0 Hz, the drive will ramp up from 0 .0 Hz when given a start command . Once running, however, the drive will not operate below the MIN FRQ setting unless the rotation is changed, or a stop command is issued and the drive is programmed to ramp to a stop . If the MINIMUM FREQUENCY is set to 0 .0 Hz, the drive may be operated in ZERO SPEED mode (drive is in RUN state, but there is no output to the motor) . ZERO SPEED operation can be used in applications requiring the ability to start and stop the drive using only the selected speed reference . The drive will start when the speed reference is raised above 0 VDC or 4 mA, and it will stop when the reference is lowered to 0 VDC or 4 mA . Note that the drive must be initially started using one of the normal start commands (keypad or terminal strip) . MAX FRQ (MAXIMUM FREQUENCY) This parameter defines the upper limit of the drive’s speed range . MAX FRQ is used in...

DC TIME should be set to the lowest value that provides satisfactory operation in order to minimize motor heating .
  • Page 53 MOTOR OL (MOTOR OVERLOAD) The MC3000 Series is UL approved for solid state motor overload protection . Therefore, a separate thermal overload relay is not required for single motor applications . The MOTOR OVERLOAD circuit is used to protect the motor from overheating due to excessive current draw . The trip time for the MOTOR OVERLOAD is based on an “inverse I t” function . This function allows the drive to deliver 150% of the rated output current for one minute, and even higher current levels for shorter periods of time . Once the overload circuit “times...
  • Page 54 Example 2: A 480 Vac, 20 HP drive is operating a motor at 10 Hz . From the diagram, a drive operating at 10 Hz can deliver about 75% of its output current rating continuously . A 480 Vac, 20 HP drive’s output current rating is 27 Amps . Therefore, the drive would be able to operate continuously at 20 Amps . The drive would also be able to deliver 150% of that value (30 Amps) for one minute before tripping into an OVERLOAD fault . The “speed compensated” thermal overload is the factory default and should be used in applications where the motor does not normally experience high loads at low speeds for extended periods of time . NOTE 1: The above diagram is based on a MOTOR OL setting of 100% . For lower MOTOR OL settings, reduce the % CURRENT values by the same percentage . For example, if MOTOR OL is set to 75%, reduce the % CURRENT values by 25% . Therefore, the curve shifts down, but the shape of the curve remains the same .

  • Page 56 CARRIER (CARRIER FREQUENCY) This parameter sets the carrier frequency, or switching frequency of the output IGBT’s . Higher switching rates result in less audible noise to be emitted from the motor, but the efficiency of the drive decreases as the carrier frequency increases . Therefore, this parameter should be set to the lowest value which yields acceptable sound levels . Available settings are: 2 .5 kHz, 6 kHz, 8 kHz, 10 kHz, 12 kHz and 14 kHz . NOTE 1: The 2 .5 kHz carrier frequency setting is a variable carrier . The carrier frequency remains fixed at 1 .5 kHz up to 25 Hz output frequency . Above 25 Hz, the carrier is a fixed multiple of 60 times the drive’s output frequency .
  • Page 57 POWER UP and AUTO 1 - 3 settings are only active when the drive is in REMOTE mode (refer to Parameter 30 - CONTROL) . When set for AUTO 1, 2, or 3, the drive will attempt five restarts after a fault . During the interval between restart attempts, the drive will display START PENDING to indicate that the equipment will automatically restart . If all five restart attempts are unsuccessful, the drive will trip into FAULT LOCkOUT, which requires a manual reset . Every 15 minutes that passes will decrement the restart counter by one . Therefore, 75 minutes after a successful restart, the restart counter is fully reset, and the drive can once again attempt five restarts . NOTE 1: When set for AUTO 1, 2, or 3, only the first two restart attempts will perform a speed search to start into a spinning load . The last three restart attempts will apply DC braking (at the voltage level programmed into Parameter 12 - DC BRAkE) for 15 seconds and then start from zero speed . NOTE 2: The drive WILL NOT restart after a CONTROL or PWR SAG fault . Also, if an OUTPUT fault occurs below 1 .5 Hz, only one restart will be attempted, after a 30 second delay . If unsuccessful, it will then trip into FAULT LOCkOUT, which requires a manual reset . This is done to protect the drive in case of a shorted motor . STOP (STOP MODE) This parameter selects whether the motor will COAST to a stop, or RAMP to a stop, when the drive is given a stop command . COAST When a stop command is given, the drive shuts off the output to the motor, allowing it to coast to a stop . In this mode, the time it takes the motor to stop is governed by the inertia of the driven load .
  • Page 58 CONTROL (START/STOP CONTROL) This parameter selects the START/STOP control source, which is either the keypad (LOCAL), the terminal strip (REMOTE), or the serial link (SERIAL) . The LOCAL/REMOTE key on the keypad is also affected by the setting of this parameter . The following settings are possible: LOCAL The drive will only respond to START/STOP commands from the keypad . The LOCAL/REMOTE key is disabled . REMOTE The drive will only respond to START/STOP commands from the terminal strip . The LOCAL/REMOTE key is disabled . SERIAL The drive will only respond to START/STOP commands through the serial link . kEYPAD The LOCAL/REMOTE key on the keypad is enabled and is used to toggle between LOCAL and REMOTE modes . Press the LOCAL/REMOTE key to select the desired mode and then press the ENTER key within three seconds .
  • Page 59 HZ MULT (HERTZ MULTIPLIER) The HZ MULTIPLIER is used to scale the output speed indication on the display . This parameter is only active when UNITS is set for sp RPM, sp /SEC, sp /MIN, or sp /HR . Multiplying the output frequency by the HZ MULTIPLIER will yield the desired speed value on the display . Example: The desired speed units is RPM with a standard 60 Hz, 1800 RPM motor . Set UNITS to sp RPM and set HZ MULT to 30 .00 . This will result in a display of 1110 RPM for an output frequency of 37 Hz (37 Hz X 30 = 1110 RPM) . Also, if there is a 100:1 gear reducer in the system, Parameter 33 - UNITS DP below could be set to XX .XX to represent the output of the gear reducer (11 .10 RPM in the example) . UNITS DP (SPEED UNITS DECIMAL POINT) In “non-PID” mode, UNITS DP selects the decimal point location of the speed display . UNITS DP has no effect if UNITS is set to sp HERTZ or sp % HZ . In PID mode, UNITS DP selects the decimal point location for the PID SETPOINT and FEEDBACk displays, and FB @ MIN and FB @ MAX .
  • Page 60 When the commanded speed falls below the SLEEP THRESHOLD setting for the defined SLEEP DELAY time (refer to Parameter 37), the drive will "go to sleep" and the motor will go to zero speed . The drive will remain "sleeping" until it is commanded to operate at a speed that is 2 Hz above the SLEEP THRESHOLD, at which point it will "wake up" and ramp the motor up to the commanded speed . NOTE 1: While the the drive is in Sleep Mode, the Status portion of the display will read SLEEP . NOTE 2: If the drive's commanded speed goes below the SLEEP THRESHOLD, the SLEEP DELAY timer will start to count down . If the commanded speed equals or exceeds the SLEEP THRESHOLD before the SLEEP DELAY times out, the SLEEP DELAY timer will be reset . NOTE 3: If the drive is in a Stop state, and the commanded speed is below the SLEEP THRESHOLD, the drive will immediately go to sleep upon a Start command, bypassing the SLEEP DELAY . SLEEP DL (SLEEP DELAY) This parameter sets the amount of time the drive must operate below the SLEEP THRESHOLD (refer to Parameter 36) before the drive "goes to sleep" and brings the motor to zero speed .
  • Page 61 TB5 MAX (TERMINAL TB-5 INPUT) This parameter selects the output frequency of the drive that will correspond to the maximum analog speed reference input (10 VDC or 20 mA) . This parameter is used in conjunction with Parameter 39 - TB5 MIN to define a speed range that corresponds to the analog speed reference input (0 - 10 VDC or 4 - 20 mA) . Example: The drive is required to operate from 0 to 60 Hz in response to a 0-5 VDC speed reference signal (rather than the “normal” 0-10 VDC) . Because TB5 MAX is based on a 0-10 VDC (or 4-20 mA) signal, the drive will operate at half of the TB5 MAX value if it is given a 5 VDC signal . Therefore, setting TB5 MAX to 120 Hz will cause the drive to run at 60 Hz when it is given a 5 VDC speed reference signal . NOTE: The drive can be programmed for inverse operation so that as the speed reference increases, the drive speed will decrease, and as the speed reference decreases, the drive speed will increase . This is accomplished by setting TB5 MIN to the desired maximum output frequency, and TB5 MAX to the desired minimum output frequency .
  • Page 62 @ TB10B (TERMINAL TB-10B SCALING) This parameter scales the analog output signal at TB-10B . This setting is the load (in %) that is indicated when the TB-10B output measures 10 VDC . Example: The drive is part of a control system that requires a 0-10 VDC signal to indicate 0-150% drive load . If this parameter is set to 150%, the drive will output 10 VDC at 150% load (and about 6 .7 VDC at 100% load) . NOTE: The output signal at TB-10B is affected by the setting of Parameter 34 - LOAD MLT . TB13A (TB-13A INPUT FUNCTION) This parameter is used to select the function of terminal TB-13A . Closing TB-13A to TB-2 activates the TB - 13A input function . The following functions can be selected: NONE Disables the TB-13A function . 0-10VDC Selects 0-10 VDC as the AUTO speed reference input (or setpoint source in PID mode) .

  • Page 66 SERIAL (SERIAL COMMUNICATIONS) This parameter is used to activate serial communications . When using this feature, the drive can communicate with a personal computer (PC), programmable logic controller (PLC), or other external device that utilizes RS-485 serial communications for control . The serial interface may be used to read present parameter settings (uploading to the control device), write new parameter settings (downloading from the control device), monitor present drive activity, and control drive activity . The following settings are available: DISABLE Serial communication function is disabled . W / TIMER Enables serial communications with a watchdog timer . If there is no serial activity (read or write) for more than 10 seconds, serial control will turn off and the drive will stop . W / O TIMR Enables serial communications without a watchdog timer . However, after 10 seconds of no serial activity, serial control can be turned off by issuing a STOP command from any source (keypad, terminal strip) other than the serial link .
  • Page 67 SOFTWARE (SOFTWARE VERSION) This parameter displays the software code and revision number of the control board software . This information is useful when contacting the factory for programming or troubleshooting assistance . This is a “view-only” parameter, and cannot be changed . MONITOR (MONITOR) This parameter is used to enable (ON) or disable (OFF) the MONITOR MODE function . The functionality is explained below: Pressing the PROG/RUN key will activate the PASSWORD prompt . If the ENTER key is pressed while the password value reads 0000, the MONITOR MODE is entered and parameters can be viewed (except for PASSWORD), but not changed .
  • Page 68 PID MODE (PID MODE SELECT) This parameter activates the PID function, and selects whether the PID control will be direct or reverse acting . Refer to Section 19 - MC3000 PID SETPOINT CONTROL . The following options are available: OFF Disables the PID function to allow “standard” drive operation . NORMAL Enables the PID function for direct acting systems . An increase in the feedback variable will cause a decrease in motor speed . REVERSE Enables the PID function for reverse acting systems . An increase in the feedback variable will cause an increase in motor speed . NOTE: The REVERSE selection is not used to compensate for reverse acting feedback devices . If a reverse acting feedback device is used, program Parameters 75 and 76 - FB @ MIN and FB @ MAX as described in Section 19 .1 - FEEDBACk DEVICES .
  • Page 69 FB @ MAX (MAXIMUM FEEDBACk VALUE) This parameter should be set to the value of the process variable that corresponds to the maximum transducer feedback signal (10 VDC or 20 mA) . NOTE: If a reverse acting feedback device is being used, FB @ MIN should be set to the maximum process variable value, and FB @ MAX should be set to the minimum process variable value . P GAIN (PROPORTIONAL GAIN) This parameter setting represents the speed command output (in % of maximum speed) that results from each 1% of error (1% of Parameter 75 - FB @ MIN or 76 - FB @ MAX, whichever is larger) . Example: If P GAIN is programmed for 5%, and the error (difference between setpoint and feedback) is 10%, the speed command output of the Proportional term is 50% (10 x 5 = 50) of maximum speed . I GAIN (INTEGRAL GAIN) This parameter setting represents the ramp rate of the speed command output (in % of maximum speed per second) that results from each 1% of error . Example: If I GAIN is programmed for 0 .5 seconds, and the error is 5%, the rate of rise of the speed command output of the Integral term is 2 .5% (0 .5 x 5 = 2 .5) of maximum speed per second . D GAIN (DIFFERENTIAL GAIN) This parameter setting represents the speed command output (in % of maximum speed) that results from each 1% per second change in the error . Example: If D GAIN is programmed for 5 seconds, and the error is increasing at 2% per second, the speed command output of the Differential term is 10% (5 x 2 = 10) of maximum speed .
  • Page 70 MAX ALRM (PID MAXIMUM ALARM) This parameter setting represents the value that the feedback signal (in PID mode) or speed reference signal (in open-loop speed mode) must exceed to activate the MIN/MAX ALARM output (refer to Parameters 52, 53, and 54) . NOTE 1: The MIN ALARM function can be used to start and stop the drive based on the level of the speed reference signal or PID feedback signal . This is done by wiring a 2-wire start/stop circuit through the drive's Form C relay or open- collector output, and setting the Form C relay or open-collector output for MIN/MAX (refer to Parameters 52, 53, and 54) . When the signal drops below the MIN ALARM setting, the relay or open-collector output will de-energize, which opens the start contact and stops the drive . When the signal is equal to or greater than the MIN ALARM setting, the relay or open-collector output will energize, which closes the start contact and starts the drive . The drive must be in REMOTE mode to use the MIN/MAX function to start and stop the drive . NOTE 2: When using the MIN and MAX ALARM functions in open-loop speed mode (PID is disabled), parameter 74 - PID FB must still be set to match the speed reference signal being used . LANGUAGE (LANGUAGE SELECTION) The MC Series drive can support other languages with the addition of an optional LANGUAGE EEPROM chip installed in socket U11 on the control board of the drive . If the EEPROM is not present, the default language will be ENGLISH . Also, this parameter is not affected when the parameters are reset using Parameter 65 - PROGRAM . Therefore,...
  • Page 71: Mc3000 Pid Setpoint Control

    MC3000 PID SETPOINT CONTROL PID Setpoint Control allows the MC3000 to maintain a process setpoint, such as PSI or CFM, without using an external controller . When PID is activated, the MC3000 will operate in a closed-loop fashion, automatically adjusting the motor speed to maintain the setpoint . PID setpoint control requires feedback from the process in order to compare the process variable “value” to the setpoint . The difference between the process variable “value” and the setpoint is called the error . The MC3000 will increase or decrease the motor speed in an attempt to minimize the error . By constantly adjusting the motor speed, the PID control will drive the process toward the setpoint . Refer to the PID block diagram below: SETPOINT Motor Process Speed Error Command Process Variable Feedback (transducer) 19 .1 FEEDBACk DEVICES A transducer or transmitter is required to monitor the process variable and provide feedback to the PID unit in order to compare the process variable feedback to the setpoint .

    Example 1: A 0-100 psi transducer outputs a 4 mA signal at 0 psi and 20 mA at 100 psi . Program Parameter 75 to 0 .0 PSI, and Parameter 76 to 100 .0 PSI (This assumes that Parameter 31 - UNITS is set to pid PSI, and Parameter 33 - UNITS DP is set to XXX .X) . For a reverse acting transducer, set Parameter 75 - FB @ MIN to the maximum process variable feedback value, and set Parameter 76 - FB @ MAX to the minimum process variable feedback value . In other words, Parameter 75 is set higher than Parameter 76 . See the example below: Example 2: A 0-100 psi transducer outputs a 20 mA signal at 0 psi and 4 mA at 100 psi . Program Parameter 75 to 100 .0 PSI, and Parameter 76 to 0 .0 PSI (This assumes that Parameter 31 - UNITS is set to pid PSI, and Parameter 33 - UNITS DP is set to XXX .X) . 19 .2 THE SYSTEM - DIRECT AND REVERSE ACTING The entire system can also be direct or reverse acting . In a direct acting system, an increase in motor speed causes an increase in the process variable . This is equivalent to requiring an increase in motor speed in response to a decreasing process variable feedback .

    In order to use TB-5A or TB-5B for a setpoint input, one of the TB-13 terminals must be programmed for the appropriate signal . Closing the TB-13 terminal to TB-2 will then select that signal as the setpoint reference . If the contact closure is not made to TB-2, the setpoint reference source will default to the keypad . Refer to Parameters 47 - TB13A, 48 - TB13B, and 49 - TB13C . Remote setpoint reference inputs at TB-5A and TB-5B can only be used if that terminal is NOT being used for the process feedback signal from a transducer . The MC3000 has only one analog input of each type, so the same type of signal cannot be used for transducer feedback and setpoint reference . For example, a 4-20 mA signal from a transducer could not be used as a feedback signal if the setpoint is being controlled by a 4-20 mA signal from a PLC .

    19 .6 MC3000 DISPLAY IN PID MODE When the drive is in PID mode, the DRIVE STATUS portion of the display will indicate actual output frequency (in Hertz) instead of RUN, and the right side of the display will indicate PID SETPOINT, % LOAD, or PID FEEDBACk . The ENTER key is used to toggle between the different displays . Examples of the possible displays are shown below: DRIVE STATUS SETPOINT 42.53 HZ 35.0 PSI UNITS DRIVE PERCENT STATUS LOAD 42.53 HZ 57% LOAD DRIVE STATUS FEEDBACK 42.53 HZ 33.7 PSI UNITS In the examples above, the drive is running at 42 .53 Hz to maintain the PID SETPOINT of 35 .0 psi . Pressing the ENTER key displays % LOAD, which is 57% . Pressing ENTER again displays the PID FEEDBACk from the process, which is 33 .7 psi . When the PID SETPOINT and PID FEEDBACk displays are entered, the display will flash SETPOINT or FEEDBACk before displaying the value to indicate which display is being viewed .
  • Page 75: Troubleshooting

    TROUBLESHOOTING The table below lists the fault conditions that will cause the drive to shut down, as well as some possible causes . Please contact the factory for more information on troubleshooting faults . NOTE: The drive will not automatically restart after a PWR SAG or a CONTROL fault . Also, if an OUTPUT fault occurs below 1 .5 Hz, the drive will only attempt one restart, after a four minute delay . If unsuccessful, it will then trip into FAULT LOCkOUT, which will require a manual reset . This is done to protect the drive in case of a shorted motor . FAULT MESSAGES FAULT DESCRIPTION POSSIBLE CAUSES OUTPUT Output transistor fault: Phase to ground short. Output current exceeded 200% Phase to phase short. of drive rating FX BOOST set too high.
