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
Base Frequency (F04)/2nd Base Frequency (A02),
1st Motor Armature Resistance (P06)/2nd Mo-
tor Armature Resistance (A20)
: Set the no-load current of the motor, or set the current
value measured when the motor is in isolated no-load
operation in 1st Base Frequency (F04)/2nd Base Fre-
quency (A02).
