Heavy Load Id Current
|
        
Sets the d-axis current to that the drive will supply to the motor to run it at a constant speed with a heavy load. Considers E5-03 [PM Motor Rated Current (FLA)] to be 100%. Usually it is not necessary to change this setting.

(-200.0 - 0.0%)

When you use an IPM motor, you can use the reluctance torque of the motor to make the motor more efficient and help conserve energy.
When you operate an SPN motor, set this parameter to 0.
Adjust this parameter in these conditions:
-
If the load is large and motor rotation is not stable, decrease the setting value.
-
If you change the E5 parameters [PM Motor Settings], set n8-49 = 0, then adjust this parameter.
