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.

Related Parameters
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).
