Setting Motor Constant Parameters
In vector control method, the motor constant parameter are set automatically using autotuning. If autotuning
does not complete normally, set them manually.

Note All factory-set parameters are for a standard 4-pole motor.
* 1. The factory settings depend on Inverter capacity (the values shown are for a 200 V Class Inverter for 0.4 kW).
* 2. The setting range is 10% to 200% of the Inverter rated output current (the values shown are for a 200 V Class Inverter for 0.4 kW).
* 3. The setting range depends on Inverter capacity (the values shown are for a 200 V Class Inverter for 0.4 kW).
Description
Sets the motor rated current in 1 A units.
These set values will become the reference values
for motor protection and torque limits.
This parameter is automatically set during auto-
tuning.
Sets the motor rated slip in Hz units.
These set values will become the reference values
for slip compensation.
This parameter is automatically set during auto-
tuning.
Sets the motor no-load current in 1 A units.
This parameter is automatically set during auto-
tuning.
Sets the number of motor poles.
This parameter is automatically set during auto-
tuning.
Sets the motor phase-to-phase resistance in Ω
units.
This parameter is automatically set during auto-
tuning.
Sets the voltage drop due to motor leakage induc-
tance as a percentage of the motor rated voltage.
This parameter is automatically set during auto-
tuning.
Sets the motor iron saturation coefficient at 50%
of magnetic flux.
This parameter is automatically set during auto-
tuning.
Sets the motor iron saturation coefficient at 75%
of magnetic flux.
This parameter is automatically set during auto-
tuning.
Sets motor iron loss in W units.
