Page 137 Note: If the frequency reference source is set for an option PCB (b1-01 = 3), but an option board is not installed, an OPE05 Operator Programming Error will be displayed on the digital operator and the drive will not run.
Page 138 Note: If b1-02 is set to 3, but an option board is not installed in CN5-A, an oPE05 operator programming error will be displayed on the digital operator and the drive will not run.
Page 139 Setting 3: Coast to Stop with Timer When the Run command is removed, the drive will turn off its output and the motor will coast to stop. If a Run command is input before the time t (value of C1-02) has expired, the drive will not start. A Run command activated during time t must be cycled after t has expired in order to start the drive.

Page 141 Whenever a Run command is active and the frequency reference is smaller than the value of parameter E1-09, the drive runs the motor at the speed set in E1-09. When the Run command is removed, the drive decelerates the motor. As soon as the motor speed reaches the zero speed level set in b2-01, Zero Speed Control is activated for the time set in b2-04.

Page 143 The Run command has to be cycled to start the drive. Note: For safety reasons, the drive is initially programmed not to accept a Run command at power up (b1-17 = 0). If a Run command is issued at power up, the RUN indicator LED will flash quickly.
Page 144: B2: Dc Injection Braking And Short Circuit Braking
WARNING! Sudden Movement Hazard. If b1-17 is set to 1 and an external Run command is active during power up, the motor will begin rotating as soon as the power is switched on. Proper precautions must be taken to ensure that the area around the motor is safe prior to powering up the drive.
Page 145 Figure 5.16 Magnetic Flux Compensation Note that the level of the DC current injected to the motor is limited to 80% of the drive rated current or to the motor rated current, whichever value is smaller.

Page 161: B6: Dwell Function
If used with induction motors, the Dwell function can help prevent speed loss when starting and stopping a heavy load. If running a PM motor in V/f control, the pause in acceleration allows the PM motor rotor to align with the stator field of the motor, thus reducing the starting current.

Page 163: B8: Energy Saving
Adjust this setting while viewing the output power monitor (U1-08) and running the drive with a light load. A low setting results in less output voltage and less energy consumption, but too small a value will cause the motor to stall.
Page 164: B9: Zero Servo
2. When the Zero Servo command has shut off, the Zero Servo Completion digital output width also shuts off. 3. Avoid using Zero Servo to lock 100% load for long periods, as this can trigger a fault. If such loads need to be held in place for long periods, either make sure the current is less than 50% of the drive rated current during Zero Servo, or use a larger capacity drive.
Page 165: C: Tuning
Deceleration Time 4 (Motor 2 Accel Time 2) <1> The setting range for the acceleration and deceleration times is determined by the accel/decel time setting units in C1-10. For example, if the time is set in units of 0.01 s (C1-10 = 0), the setting range becomes 0.00 to 600.00 s.
Page 166 = 16), parameters C1-01 to C1-04 become accel/ decel time 1 and 2 for motor 1, while C1-05 to C1-08 become accel/decel time 1 and 2 for motor 2. Accel/decel times 1 and 2 can be switched for each motor using a digital inputs set to H1-...
Page 167: C2: S-Curve Characteristics
Setting 0: 0.01 s units The accel/decel times are set in 0.01 s units. The setting range will be 0.00 to 600.00 s. If any of the parameters C1-01 to C1-09 is set to 600.1 seconds or more, then C1-10 cannot be set to 0.
Page 168 Determined by A1-02 Note: Default setting is 0.0 in V/f Control (A1-02 = 0), and 1.0 in Open Loop Vector Control (A1-02 = 2). In Closed Loop Vector Control, slip compensation is used correct inaccuracies that can result from temperature fluctuation in the rotor.
Page 169 Determined by E3-01 Note: Default setting is 0.0 in V/f Control (A1-02 = 0). Default setting is 1.0 in Open Loop Vector Control (A1-02 = 2) and Closed Loop Vector Control (A1-02 = 3). In Closed Loop Vector Control, slip compensation gain acts as an adaptable gain.
Page 170: C4: Torque Compensation
Adjust C4-01 so that the output current does not exceed the drive rated current. Note: 1. Refrain from adjusting torque compensation in Open Loop Vector Control, as it can have a negative effect on torque accuracy. 2. Refrain from adjusting this parameter in OLV/PM. Too high a value can cause overcompensation, resulting in motor oscillation.

Page 174 In these control modes, parameters C5-03 and C5-04 define the ASR gain an integral time at zero speed. The settings in C5-01 and C5-02 are used at speeds above the setting in C5-07. C5-07 is set to 0 as the default so that C5-01 and C5-02 are used over the entire speed range.
Page 175 Enables integral operation during acceleration and deceleration. Integral operation should be used when driving a heavy load or a high inertia load, but can cause problems with overshoot at the end of acceleration and deceleration. Refer to ASR Setup Problems and Corrective Actions on page 173 to solve such problems.
Page 176 C5-25: Motor 2 ASR Limit ■ Functions for motor 2 in the same way that C5-05 functions for motor 1. Sets the ASR output limit for motor 2 as a percentage of the maximum output frequency (E4-04). For more details, see C5-05: ASR Limit on page 174.
Page 177: C6: Carrier Frequency
Reset when C6-01 is changed. Note: The default setting for the carrier frequency differs based on the type of motor and the Duty Mode selection. The default is 2 kHz when the drive is set for Heavy Duty performance, and defaulted to “Swing PWM1” when set for Normal Duty performance.
Page 178 <1> The carrier frequency may need to be lowered if the motor cable is too long. Refer to the table below. <2> In Normal Duty, the carrier frequency default is for Swing PWM (C6-02 = 7), the same as setting 2 kHz. Increasing the carrier frequency is fine when the drive is set for Normal Duty, but remember that the drive rated current falls when the carrier frequency is increased.
Page 179 The tables below show the drive output current depending on the carrier frequency settings. The 2 kHz value is equal to the Normal Duty rated current. If the carrier frequency is increased above 2 kHz in ND, the rated output current is reduced.
Page 180: D: Reference Settings
<1> The upper limit is determined by the maximum output frequency (E1-04) and upper limit for the frequency reference (d2-01). <2> Setting units are determined by parameter o1-03. The default is “Hz” (o1-03 = 0) in V/f, V/f w/PG, OLV, CLV, and OLV/PM control modes.
Page 181 5.4 d: Reference Settings • When the an analog input is set to “Auxiliary frequency 2” (H3-02, H2-06, or H2-10 = 3), then the value set to this input will be used as the Multi-Step Speed 3 instead of the value set to parameter d1-03. If no analog inputs are set for “Auxiliary frequency 2”, then d1-03 becomes the reference for Multi-Step Speed 3.
Page 182: D2: Frequency Upper/Lower Limits
Sets the minimum frequency reference as a percentage of the maximum output frequency. This limit applies to all frequency references. If a lower reference than this value is entered, the drive will run at the limit set to d2-02. If the drive is started with a lower reference than d2-02, it will accelerate up to d2-02.
Page 183: D4: Frequency Reference Hold And Up/Down 2 Function
Figure 5.44 Jump Frequency Operation Note: 1. The drive will use the active accel/decel time to pass through the specified dead band range, but will not allow continuous operation in that range. 2. When setting more than one Jump frequency, make sure that d3-01 ≥ d3-02 ≥ d3-03.
Page 184 • Up/Down 2 with frequency reference from input sources other than the digital operator When a Run command is active and the Up/Down 2 command is released for longer than 5 s, the bias value will be saved in parameter d4-06. When restarting after the power is switched off, the drive will add the value saved in d4-06 as a bias to the frequency reference.
Page 185 Setting d4-03 ≠ 0.0 Hz When an Up 2 or Down 2 command is enabled, the bias is increased or decreased in steps for the value set in d4-03. The frequency reference changes with the accel/decel times determined by parameter d4-04.
Page 186 Setting 1: Reset Bias Value The bias is reset to 0% when both inputs Up 2 and Down 2 are either on or off. The drive will use the accel/decel time as selected in d4-04 to accelerate or decelerate to the frequency reference value.
Page 187 Set this parameter to an appropriate value before using the Up/Down 2 function. Note: When the frequency reference is set by the digital operator (b1-01 = 0) and d4-01 = 1, the bias value will be added to the frequency reference if no Up/Down 2 command is received for 5 s, and will be reset to 0 afterwards.

H parameters are used to assign functions to the external terminals. ◆ H1: Multi-Function Digital Inputs H1-01 to H1-08: Functions for Terminals S1 to S8 ■ These parameters assign functions to the multi-function digital inputs. The various functions and their settings are listed below in Table 5.35.
Page 215 Note: 1. The Run command must be closed for more than 2 ms. 2. If the Run command is active at power up and b1-17 = 0 (Run command at power up not accepted), the Run LED will flash to indicate that protective functions are operating.
Page 216 Baseblock (Interrupt output) NOTICE: If using baseblock in hoist applications, make sure the brake closes when the drive output is cut off by a Baseblock command triggered via one of the input terminals. Failure to do so will result in the motor suddenly coasting when the Baseblock command is entered, causing the load to slip.
Page 217 When a Run command is applied, the lower limits work as follows: • If the lower limit is set by d2-02 only, the drive will accelerate to this limit as soon as a Run command is entered. • If the lower limit is determined by an analog input only, the drive will accelerate to the limit as long as the Run command and an Up or Down command are active.
Page 218 5.7 H: Terminal Functions • If the lower limit is set by both an analog input and d2-02, and the analog limit is higher than the d2-02 value, then the drive will accelerate to the d2-02 value when a Run command is input. Once the d2-02 value is reached, it will continue acceleration to the analog limit only if an Up or Down command is set.
Page 219 F1-02 to F1-04, F1-08 to F1-11, F1-14, F1-31 to F1-37 Note: 1. When using 2 motors, the motor overload protection selection (oL1) set to L1-01 applies to both motor 1 and motor 2. 2. It is not possible to switch between motor 1 and motor 2 during run. Doing so will trigger the “rUn” alarm.
Page 220 Once the Analog Frequency Reference Sample/Hold function is held for at least 100 ms, the drive reads the analog input and changes the frequency reference to the newly sampled speed as illustrated in Figure 5.62.
Page 221 Configures the drive for a 2-wire sequence. When an input terminal set to 40 closes, the drive operates in the forward direction. When an input set for 41 closes, the drive will operate in reverse. Closing both inputs at the same time will result in an external fault.

Page 228 DC bus voltage has fallen below the trip level set to L2-05. Setting 8: During baseblock (N.O.) Output closes to indicate that the drive is in a baseblock state. While in baseblock, output transistors do not switch and no main circuit voltage is output.
Page 229 Setting F: Through mode Select this setting when using the terminal in a pass-through mode. When set to F, an output does not trigger any function in the drive. Setting F, however, still allows the output status to be read by a PLC via a communication option or MEMOBUS/Modbus communications.
Page 230 Output opens when the output frequency or motor speed (CLV, CLV/PM) rises above the detection level set in L4-03 plus the detection with set in L4-04. The terminal remains open until the output frequency or motor speed falls below the level set in L4-03.
Page 231 An output set for “Restart enabled” closes once the drive begins attempting to restart after a fault has occurred. The fault restart function allows the drive to automatically clear a fault. The terminal set to 1E will close after the fault is cleared and the drive has begun attempting to restart.

Setting 1: Recover within L2-02 When a momentary power loss occurs, the drive output will be shut off. Should the power return within the time set to parameter L2-02, th e drive will perform Speed Search and attempt to resume operation.
Page 250 • The DC bus voltage fell below the level specified in L2-05. The KEB operation will start as specified in L2-29. Note: KEB Ride-Thru 1 and 2 cannot both be assigned to input terminals at the same time. Attempting this will trigger an oPE3 error.
Page 251 L2-11, then normal operation is resumed. Note: The time set in L2-02 has priority over L2-10. Even if L2-10 is set to a longer time than L2-02, once the time in L2-02 passes, the drive will check the DC bus voltage level and the status of the terminal assigned to KEB Ride-Thru, then try to restart.
Page 252 = 65, 66, 7A, 7B). After decelerating for the time set in parameter L2-10, the drive checks the DC bus voltage and the status of the digital input. If the DC bus voltage is still below the level set in L2-11 or if the digital input assigned to KEB Ride-Thru is still active, then the drive continues to decelerate.
Page 253 System KEB Ride-Thru 1 is used. Note: 1. Make sure the Run command is not switched off during momentary power loss. If the Run command is shut off, the drive will not accelerate back to speed when the power is restored.

Page 256 <1> Setting 2 is not available for PM OLV. Setting 0: Disabled No Stall Prevention is provided. If the acceleration time is too short, the drive may not be able to get the motor up to speed fast enough, thus tripping an overload fault.
Page 257 <1> <1> The upper limit and default value is determined by the duty rating and the carrier frequency derating selection (C6-01 and L8-38 respectively). • Stalling may occur when the motor is rated at a smaller capacity than the drive and the Stall Prevention default settings are used.
Page 258 Setting 2: Intelligent Stall Prevention With this setting, the drive adjusts the deceleration rate so that the DC bus voltage is kept at the level set in parameter L3- 17. This way the shortest possible deceleration time is achieved while the motor is protected from stalling. The deceleration time that has been selected is disregarded, but the achievable deceleration time cannot be smaller than 1/10 of the set deceleration time.
Page 259 2. When output frequency is 6 Hz or less, Stall Prevention during run is disabled regardless of the setting in L3-05 and L3-06. Setting 0: Disabled Drive runs at the set frequency reference. A heavy load may cause the motor to stall and trip the drive with an oC or oL fault.

Setting 1: Count restart attempts The drive will try to restart using the time interval set in parameter L5-04. A record is kept of the number of attempts to restart to the drive, regardless of whether or not those attempts were successful. When the number of attempted restarts exceeds the value set to L5-01, the drive gives up trying to restart.
Page 265 Note: 1. The torque detection function uses a hysteresis of 10% of the drive rated output current and motor rated torque. 2. In V/f, V/f w/PG and OLV/PM, the level is set as a percentage of the drive rated output current. In OLV, CLV, AOLV/PM and CLV/ PM, it is set as a percentage of the motor rated torque.
Page 266 These parameters set the detection levels for the torque detection functions 1 and 2. In V/f and OLV/PM control modes these levels are set as a percentage of the drive rated output current, while in vector control modes these levels are set as a percentage of the motor rated torque.

Notes on using High Slip Braking: • The deceleration time that has been set is ignored during HSB. Use Overexcitation Deceleration 1 (L3-04 = 4) or a dynamic braking option if the motor has to be stopped in a defined time.
Page 277 • Lower this setting if motor current is too high during HSB. High current can damage the motor due to overheat. • The default setting is 150% when the drive is set for Heavy Duty, and 120% when the drive is set for Normal Duty.

Selects how the rotor position is detected at start. Note: 1. In CLV/PM, the drive performs a magnetic pole search the first time it starts the motor. After that, rotor position is calculated from the PG encoder signal and saved until the drive is switched off. Parameter n8-35 determines how this initial pole search operates.
Page 282 Although this setting rarely needs to be changed, adjustment may be necessary under the following conditions: • Increase this setting when it takes too long for the reference value of the pull-in current to match the target value. • Decrease this setting if motor oscillation occurs.

The master performs serial communications with only one slave at a time. The address or node for each slave must be set beforehand so that the master can communicate with the slave at that address. A slave that receives a command from the master will perform the specified function and then send a response back to the master.

Page 482: C.4 Memobus/Modbus Setup Parameters
For serial communications to work, each individual slave drive must be assigned a unique slave address. Setting H5-01 to any value besides 0 assigns the drive its address in the network. Slave address don’t need to be assigned in sequential order, but each address needs to be unique so that no two drives have the same address.
Page 483 No communication error detection. The drive continues operation. Setting 1: Enabled If the drive does not receive data from the master for longer than the time set to H5-09, then a CE fault will be triggered and the drive will operate as determined by parameter H5-04.

MEMOBUS/Modbus communications are both linked by an OR operation. ◆ Controlling the Drive To start and stop the drive or set the frequency reference using MEMOBUS/Modbus communications, an external reference must be selected and the parameters listed in Table C.1 must be adjusted accordingly.
Page 486: C.6 Communications Timing
<1> <1> If the drive receives command type 1 data during the minimum wait time, it will perform the command and then respond. However, if it receives a command type 2 or 3 during that time, either a communication error will result or the command will be ignored.
Page 487: C.7 Message Format
◆ Slave Address The slave address in the message defines the note the message is sent to. Use addresses between 0 and FF (hex). If a message with slave address 0 is sent (broadcast), the command from the master will be received by all slaves. The slaves do not provide a response to a broadcast type message.
Page 488 Response Data ■ To be sure that the data is valid, perform a CRC-16 calculation on the response message data as described above. Compare the result to the CRC-16 checksum that was received within the response message. Both should match.
Page 489: C.8 Message Examples
Function code 10h allows the user to write multiple drive MEMOBUS/Modbus registers with one message. This process works similar to reading registers, i.e., the address of the first register that is to be written and the data quantity must be set in the command message.

D.3 UL Standards The UL/cUL mark applies to products in the United States and Canada. It indicates that UL has performed product testing and evaluation, and determined that their stringent standards for product safety have been met. For a product to receive UL certification, all components inside that product must also receive UL certification.
Page 516: Drive Motor Overload Protection
This drive has undergone the UL short-circuit test, which certifies that during a short circuit in the power supply, the current flow will not rise above 100,000 amps at 240 V for 200 V class drives and 480 V for 400 V class drives.
Page 517 Parameter L1-02 determines how long the motor is allowed to operate before the oL1 fault occurs when the drive is running at 60 Hz and at 150% of the full load amp rating (E2-01) of the motor. Adjusting the value of L1-02 can shift the set of oL1 curves up the y axis of the diagram below, but will not change the shape of the curves.
Page 518: D.4 Safe Disable Input Function
NOTICE: From the moment terminal inputs H1 and H2 have opened, it takes up to 1 ms for drive output to shut off completely. The sequence set up to trigger terminals H1 and H2 should make sure that both terminals remain open for at least 1 ms in order to properly interrupt drive output.
Page 519 (baseblock), but does not create a “Safe Torque Off” status. Note: To avoid an uncontrolled stop during normal operation, make sure that the Safe Disable inputs are opened first when the motor has completely stopped.
Page 520: Disable Monitor Output Function/Digital Operator Display
When both Safe Disable inputs are open, “Hbb” will flash in the digital operator display. Should only one of the Safe Disable channels be on while the other is off, “HbbF” will flash in the display to indicate that there is a problem in the safety circuit or in the drive. This display should not appear under normal conditions if the Safe Disable circuit is utilized properly.
