Decreasing Motor Speed Fluctuation; Slip Compensation (N002 = 0) - Omron V7-IP65 User Manual

Decreasing Motor Speed Fluctuation

Slip Compensation (n002 = 0)

As the load becomes larger, the motor speed is reduced and the motor
slip value is increased. The slip compensating function controls the
motor speed at a constant value even if the load varies.
When the Inverter output current is equal to the Motor Rated Current
(n036), the compensation frequency is added to the output frequency.

* Depends on Inverter capacity. (Refer to pages 235 and 235.)
Note: 1. Slip compensation is not performed under the following condition:
Output frequency Minimum Output Frequency (n016)
2. Slip compensation is not performed during regeneration.
3. Slip compensation is not performed when the Motor Rated Current
(n036) is set to 0.0 A.
