PM E-Save Coefficient Kt
|
    
Sets torque linearity. This parameter uses the Kt value from the motor nameplate. Usually it is not necessary to change this setting.
|
1.00
(0.00 - 3.00)

When E5-01 = 1xxx [PM Motor Code Selection = Yaskawa SSR1 series IPM motor], the drive automatically calculates the energy-saving coefficient Kt and uses that value to control operation.
Do this procedure to prevent oscillation when you set b8-01 = 1 [Energy Saving Control Selection = Enabled].
-
Check U5-22 [Energy Save Coeff Kt] and make sure that it aligns with the Kt value on the motor nameplate.
-
If the numbers are different, set b8-17 to the Kt value on the motor nameplate.
