Setting Motor Constants
In vector control method, the motor constants are set automatically using autotuning. If autotuning does not
complete normally, set them manually.
Related Constants
* 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).
