Wiring the Main Circuits This section describes wiring connections for the main circuit inputs and outputs. Wiring Main Circuit Inputs Observe the following precautions for the main circuit power supply input. Installing a Molded-case Circuit Breaker Always connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via a molded-case circuit breaker (MCCB) suitable for the Drive.
Page 26
Wiring Main Circuit Terminals Installing a Magnetic Contactor If the power supply for the main circuit is to be shut off during a sequence, a magnetic contactor can be used. When a magnetic contactor is installed on the primary side of the main circuit to forcibly stop the Drive, however, the regenerative braking does not work and the Drive will coast to a stop.
Page 27
Incorrect Noise Filter Installation • Power supply MCCB Drive MCCB General- Other purpose controllers noise filter Power MCCB supply General- Drive purpose noise filter MCCB Other controllers Do not use general-purpose noise filters. General- purpose noise filter can not effectively suppress noise generated from the Drive.
Page 28
Wiring Main Circuit Terminals Do Not Use an Electromagnetic Switch Never connect an electromagnetic switch (MC) between the Drive and motor and turn it ON or OFF during operation. If the MC is turned ON while the Drive is operating, a large inrush current will be created and the overcurrent protection in the Drive will operate.
Page 29
Countermeasures Against Radio Interference Radio noise is generated from the Drive as well as from the input and output lines. To reduce radio noise, install noise filters on both input and output sides, and also install the Drive in a totally enclosed steel box. The cable between the Drive and the motor should be as short as possible.
(1.25) * 1. Use shielded twisted-pair cables to input an external frequency reference. * 2. Magnetek recommends using straight solderless terminals on digital inputs to simplify wiring and improve reliability. * 3. Magnetek recommends using a thin-slot screwdriver with a 3.5 mm blade width.

Drive Mode Indicators Verify Mode Verify mode is used to display any parameters that have been changed from their default settings in a programming mode or by autotuning. “None” will be displayed if no settings have been changed. Of the environment mode settings, only A1-02 will be displayed if it has been changed. Other environment modes settings will not be displayed even if they have been changed from their default settings.
When V/f control has been selected, stationary autotuning for only line-to-line resistance can be selected. When the motor cannot be disconnected from the load, perform stationary autotuning. Contact your Magnetek representatives to set motor parameters by calculation. The Drive's autotuning function automatically determines the motor parameters, while a servo system's auto- tuning function determines the size of a load, the drives autotuning functions are fundamentally different.

Page 196
Frequency Reference Inputting the Frequency Reference Using Voltage (Analog Setting) When b1-01 is set to 1, you can input the frequency reference from control circuit terminal A1 (voltage input), or control circuit terminal A2 (voltage or current input). Inputting Master Speed Frequency Reference Only When inputting a voltage for the master speed frequency reference, input the voltage to control circuit termi- nal A1.
Page 197
Switch between 2 Step Speeds: Master/Auxiliary Speeds When switching between the master and auxiliary speeds, connect the master speed frequency reference to control circuit terminal A1 or A2 and connect the auxiliary speed frequency reference to terminal A3. The ref- erence on terminal A1 or A2 will be used for the Drive frequency reference when the multi-function input allocated to multi-speed command 1 is OFF and the reference on terminal A3 will be used when it is ON.
Using Multi-Step Speed Operation With M-Force GP1000 series Drives, you can change the speed to a maximum of 17 steps, using 16 frequency ref-erences, and one jog frequency reference. The following example of a multi-function input terminal function shows a 9-step operation using multi-step references 1 to 3 and jog frequency selection functions.
Page 199
Setting Precautions When setting analog inputs to step 1 to step 3, observe the following precautions. When setting terminal A1's analog input to step 1, set b1-01 to 1, and when setting d1-01 (Frequency Ref- • erence 1) to step 1, set b1-01 to 0. When setting terminal A2's analog input to step 2, set H3-09 to 2 (auxiliary frequency reference).

Page 205
DC Braking Stop If the stop command is input (i.e., the run command is turned OFF) when b1-03 is set to 2, a wait is made for the time set in L2-03 (Minimum Baseblock (BB) Time) and then the DC injection brake current set in b2-02 is sent to the motor to apply a DC injection brake to stop the motor.
Stopping Methods Using the DC Injection Brake Set parameter b2-03 to apply the DC injection brake voltage to the motor while it is coasting to a stop, to stop the motor and then restart it. Set b2-03 to 0 to disable the DC injection brake at start. Set the DC injection brake current using b2-02.
Changing the DC Injection Brake Current Using an Analog Input If you set H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-function Analog Input Terminal A3 Function Selection) to 6 (DC injection brake current), you can change the DC injection brake current level using the analog input.
Acceleration and Deceleration Characteristics Acceleration and Deceleration Characteristics This section explains the acceleration and deceleration characteristics of the Drive.

Acceleration and Deceleration Characteristics Switching Acceleration and Deceleration Time Using Multi-Function Input Terminal Commands Using the Drive, you can set four acceleration times and four deceleration times. When the multi-function input terminals (H1-) are set to 7 (acceleration/deceleration time selection 1) and 1A (acceleration/decel- eration time selection 2), you can switch the acceleration/deceleration time even during operation by combin- ing the ON/OFF status of the terminals.

Acceleration and Deceleration Characteristics Accelerating and Decelerating Heavy Loads (Dwell Function) The dwell function stores the output frequency when starting or stopping heavy loads. By temporarily storing the output frequency, you can prevent the motor from stalling. When using the dwell function, you must select a deceleration stop.
Preventing the Motor from Stalling During Acceleration (Stall Prevention During Acceleration Function) The Stall Prevention During Acceleration function prevents the motor from stalling if a heavy load is placed on the motor, or sudden rapid acceleration is performed. If you set L3-01 to 1 (enabled) and the Drive output current exceeds the -15% level of the set value in L3-02, the acceleration rate will begin to slow down.

Preventing Overvoltage During Deceleration (Stall Prevention During Deceleration Function) The Stall Prevention During Deceleration function makes the rate of deceleration more gentle to suppress increases in DC bus voltage when the DC bus voltage exceeds the set value during motor deceleration. This function automatically lengthens the deceleration time with respect to the bus voltage, even if the decel- eration time has been set to a considerably small value.

Improved Operating Efficiency This section explains functions for improving motor operating efficiency. Reducing Motor Speed Fluctuation (Slip Compensation Function) When the load is large, the amount of motor slip also grows large and the motor speed decreases. The slip compensation function controls the motor at a constant speed, regardless of changes in load.

V/f control without PG: 0.0 • Open-loop vector control: 1.0 • Flux vector control: 1.0 • Set C3-01 to 1.0 to compensate the rated slip set using the rated torque output status. Adjust the slip compensation gain using the following procedure.

Adjusting ASR Integral Time 1 (C5-02) This parameter sets the speed control (ASR) integral time. Lengthening the integral time lowers the responsiveness, and weakens the resistance to external influences. Oscillation will occur if this setting is too short. The following diagram shows the type of changes that can occur in the response when the ASR integral time is changed.
Page 325
Individual Functions High-speed Gain Adjustments (C5-01, C5-02) Adjust these parameters at normal operating speed. Increase C5-01 (ASR proportional gain 1) until there is no oscillation. Decrease C5-02 (ASR integral time 1) until there is no oscillation. Refer to Fine Adjustments on page 6 - 131 for details on making fine adjustments of high-speed operation.
Gain Adjustments at Minimum Output Frequency Operate the motor at the minimum output frequency. Increase C5-03 (ASR proportional gain 2) to a level where there is no oscillation. Decrease C5-04 (ASR integral time 2) to a level where there is no oscillation. Monitor the Drive's output current and verify that it is less than 50% of the Drive rated current.
Individual Functions Setting Precautions Droop control is disabled if b7-01 is set to 0.0. • Set b7-01 to the amount of slip as the percentage of slip when the maximum output frequency is input and • the rated torque is generated.

An error code will be displayed on the Digital Operator. If a Digital Operator key is pressed when an error code is being displayed, the display will be cleared and 03-01 will be displayed.
Troubleshooting Due to parameter setting errors, faulty wiring, and so on, the Drive and motor may not operate as expected when the system is started up. If that should occur, use this section as a reference and apply the appropri- ate measures.
Troubleshooting If the Motor Does Not Operate Use the following information if the motor does not operate. The motor does not operate when the RUN Key on the Digital Operator is pressed. The following causes are possible. If the Drive is not in drive mode, it will remain in ready status and will not start. Press the Menu Key to display the drive mode, and enter the drive mode by pressing the DATA/ENTER Key.
Page 375
The operation method selection is wrong. If parameter b1-02 (reference selection) is set to 0 (Digital Operator), the motor will not operate when an external operation signal is input. Set b1-02 to 1 (control circuit terminal) and try again. Similarly, the motor will also not operate if the LOCAL/REMOTE Key has been pressed to switch to Digital Operator operation.
Troubleshooting If the Direction of the Motor Rotation is Reversed If the motor operates in the wrong direction, the motor output wiring is faulty. When the Drive T1(U), T2(V), and T3(W) are properly connected to the motor T1(U), T2(V), and T3(W), the motor operates in a forward direction when a forward run command is executed.
If the Motor Operates Higher Than the Reference Use the following information if the motor operates higher than the reference. The analog frequency reference bias setting is wrong (the gain setting is wrong). The frequency reference bias set in parameter H3-03 is added to the frequency reference. Check to be sure that the set value is suitable.
Troubleshooting If Motor Deceleration is Slow Use the following information when the motor deceleration is slow. The deceleration time is long even when braking resistor is connected. The following causes are possible. “Stall prevention during deceleration enabled” is set. When braking resistor is connected, set parameter L3-04 (Stall Prevention Selection during Deceleration) to 0 (disabled) or 3 (with braking resistor).
If the Motor Overheats Take the following steps if the motor overheats. The load is too big. If the motor load is too heavy and the motor is used with the effective torque exceeding the motor's rated torque, the motor will overheat. Some motor rating are given for short period performance and are not contin- uous ratings.
Troubleshooting If the Ground Fault Interrupter Operates When the Drive is Run The Drive performs internal switching, so there is a certain amount of leakage current. This may cause the ground fault interrupter to operate and cut off the power supply. Change to a ground fault interrupter with a high leakage detection level (i.e., a sensitivity current of 200 mA or greater per Unit, with an operating time of 0.1 s or more), or one that incorporates high frequency countermeasures (i.e., one designed for use with Drives).
Oscillation and hunting are occurring with V/f w/PG control. The gain adjustment may be insufficient. Adjust the various types of speed control loop (ASR) gain. If the oscillation cannot be eliminated in this way, set the hunting prevention selection (parameter n1-01) to 0 (disabled) and then try adjusting the gain again.
Troubleshooting If Output Frequency Does Not Rise to Frequency Reference Use the following information if the output frequency does not rise to the frequency reference. The frequency reference is within the jump frequency range. When the jump frequency function is used, the output frequency does not change within the jump frequency range.
Maintenance and Inspection Outline of Maintenance The maintenance period of the Drive is as follows: Maintenance Period: Within 18 months of shipping from the factory or within 12 months of being delivered to the final user, whichever comes first. ...
Maintenance and Inspection Periodic Maintenance of Parts The Drive is configured of many parts, and these parts must be operating properly in order to make full use of the Drive functions. Among the electronic components, there are some that require maintenance depending on their usage condi- tions.

Application Function Precautions Observe the following precautions when using the application functions. Perform rotational autotuning during trial operation whenever it is possible to separate the motor and • machine. To achieve the characteristics of vector control described in Table 10.1, the control must be adjusted within a range that the machine will not vibrate after rotational autotuning has been performed.
Page 394
M-Force GP1000 Control Modes Load torque (%) Driving torque Speed (Hz) -100 Regenerative torque -200 With torque control, operate within a speed control range of 1:10 on the regenerative side. Precautions on Setting Parameters If the parameters are not set properly, performance may be adversely affected.
Control Modes and Applications V/f Control without PG (A1-02 = 0) V/f control without a PG is suitable for applications where multiple motors are operated with a single Drive, such as with multi-motor drives. (Thermal relay) Inverter Fig 10.1 V/f Control with PG (A1-02 = 1) V/f control with a PG enables precise control of machine line speed.
Although the Drive's protective functions will stop operation when a fault occurs, the motor will not stop immediately. Always provide mechanical stop and protection mechanisms on equipment requiring an emer- gency stop. Options Terminals B1, B2, 3 are for connecting only the options specifically provided by Magnetek. Never connect any other devices to these terminals.
Installation Observe the following precautions when installing Drive. Installation in Enclosures Either install the Drive in a clean location not subject to oil mist, airborne matter, dust, and other contaminants, or install the Drive in a completely enclosed panel. Provide cooling measures and sufficient panel space so that the temperature surrounding the Drive does not go beyond the allowable temperature.
Drive Application Precautions Handling Observe the following precautions when wiring or performing maintenance for Drive. Wiring Check The Drive will be internally damaged if the power supply voltage is applied to output terminal U/T1, V/T2, or . Check wring for any mistakes before supplying power. Check all wiring and sequences carefully. W/T3 Magnetic Contactor Installation Do not start and stop operation frequently with a magnetic contactor installed on the power supply line.
Cooling effects diminish in the low-speed range, resulting in an increase in the motor temperature. Therefore, the motor torque should be reduced in the low-speed range whenever using a motor not made by Magnetek. If 100% torque is required continuously at low speed, consider using a special drive or vector motor.
Motor Application Precautions Using the Drive for Special Motors Observe the following precautions when using a special motor. Pole-changing Motor The rated input current of pole-changing motors differs from that of standard motors. Select, therefore, an appropriate Drive according to the maximum input current of the motor to be used. Before changing the num- ber of poles, always make sure that the motor has stopped.
