5.2 MOT Group (MOT)
5.2.1 MOT-01 Set the motor related parameters.
30.00–180.00 (Hz) PM S/L2
0, 170-480 (V), 525-600 (V)
Motor Data Setting Details
Set the capacity of the motor connected to the inverter.
Set the name plate frequency of the motor connected to the inverter.
Enter the number of poles from the motor name plate.
Enter the slip RPM’s from the motor name plate. This may be shown in
Hz. If so, convert to RPM’s. Slip frequency may also be calculated.
=Rated slip frequency
=Rated frequency
=Number of the rated motor rotations
=Number of motor poles
Enter the rated current from the motor name plate.
Enter the measured no-load current at the rated frequency. If no-load
current is difficult to measure, enter a current equivalent to 30–50% of
the rated motor current.
Enter the motor rated voltage. See Output Voltage Setting below.
Enter the efficiency from the motor name plate.
5.2.2 MOT-07 Output Voltage Setting
Output voltage settings are required when a motor’s rated voltage differs from the input voltage to
the inverter. Set MOT-07 to configure the motor’s rated operating voltage. The set voltage
becomes the output voltage of the inverter at the base frequency (MOT-02). When the inverter
operates above the base frequency and when the motor’s voltage rating is lower than the input
voltage, the inverter adjusts the voltage and supplies the motor to the voltage set at MOT-07
(motor rated voltage). If the motor’s rated voltage is set higher than the input voltage at the inverter,
the inverter will output a voltage based on the input voltage.
