C3 Motor Slip Compensation
As the load becomes larger, the motor speed is reduced and motor slip increases. The slip compensa-
tion function keeps the motor speed constant even under varying load conditions.
Setting Range: 0.0 to 2.50
Factory Default: 1.0
This function controls the output frequency in response to the load’s torque demand. Increase the set
value in one tenth (0.1) increments when operating at low speeds; decrease the set value as the motor
speed increases.
During flux vector control, this gain compensates for motor slip causes by changes in temperature.
Normally, this setting does not have to be modified.
Note:
Default factory setting will be 0.0 when parameter A1-02=0 [V/F mode]. When parameter A1-
02=2 [Open Loop Vector] or 3 [Flux Vector] the default factory setting will be 1.0.
Setting Range: 0 to 10000ms
Factory Default: 200ms
Adjust the slip compensation delay time when motor speed is unstable or speed response is slow.
Increase the set value in 10ms increments when operating at low speeds; decrease the set value as the
motor speed increases.
Sets the slip compensation limit as a percentage of motor rated slip (E2-02).
