Motor Parameter Settings
• Ordinarily, offline auto-tuning is performed to set motor parameters.
However, if offline auto-tuning ends in error, for example, when the inverter does not reach 50% of
its rated current during auto-tuning, set the motor parameters manually.
• To increase the performance of vector control, set each parameter value again according to the mo-
tor in use.
• Obtain the motor's datasheet from the motor manufacturer and set each motor parameter.
For the following set values, set the data for one phase in a Y-connection after conversion in 1st
