Adjust the slip compensation primary delay time if the motor slip compensation responsiveness is low,
or if the speeds are unstable. (This does not normally need to be set.) If responsiveness is low, lower the
set value. If speeds are unstable, raise the set value.

Parameter C3-03 sets the slip compensation limit as a percentage of motor rated slip (E2-02), with the
motor rated slip taken as 100%.
If the speed is lower than the target value and does not change even when the slip compensation gain is
adjusted, it is possible that the slip compensation limit has been reached. Raise the limit and then check
again. Make sure, however, that the value of the sum of the command frequency and the slip com-
pensation limit does not exceed the speed capacity of the machinery.

Slip compensation disabled during regeneration
1
Slip compensation enabled during regeneration
Parameter C3-04 enables or disables slip compensation during regeneration. The amount of regenera-
tion is momentarily increased when this function is used, so some control option (e.g., control resistor,
Control Resistor Unit, Braking Unit) may be required.
H
Setting the Torque Compensation Function (C4)
The torque compensation function detects increases in the motor load, and increases the output torque
to compensate.
