Sets the slip compensation upper limit. Set as
a percentage of motor rated slip (E2-02).
Disabled when Simple V/f Control with PG
(H6-01 = 3) is used.
Selects slip compensation during
regenerative operation.
0: Disabled
1: EnabledUsing the Slip Compensation
function during regeneration may require a
braking option to handle momentary
increasing regenerative energy.
Selects if the motor magnetic flux is reduced
during output voltage saturation.
0: Disabled
1: Enabled
C4: Torque Compensation
Use C4 parameters to configure Torque Compensation function.
V/f control: Sets the gain for the automatic
torque (voltage) boost function and helps to
produce better starting torque.
Increase this setting when using a long motor
cable or when the motor is significantly
smaller than the drive capacity.
Decrease this setting when motor oscillation
occurs. Set the value so that the current at
low speed does not exceeds the drives rated
current.
Open Loop Vector: Sets the torque
compensation function gain. Normally no
change is required.
Sets the torque compensation filter time.
Increase this setting when motor oscillation
occurs.
Reduce the setting if there is not enough
response from the motor.
Sets torque compensation at forward start as
a percentage of motor torque.
Sets torque compensation at reverse start as a
percentage of motor torque.
