5.12.1 Slip Compensation V/F
 This parameter can set the compensation frequency so that the motor running speed at the rated current can be
closer to the set speed, thereby improving the accuracy of speed control.

Execute slip compensation with target frequency as
standard. The quantity of compensation set to 10 is 3% of
target frequency.
Note: 1. This function is only valid under V/F control 00-21(P.300)=0.
2. At the process of slip compensation, the output frequency may be larger than the set frequency.
5.12.2 Vibration inhibition
 It is used to suppress the large fluctuation of inverter output current, large fluctuation of motor speed and motor
vibration.

If the motor vibrates at a higher frequency, adjust the set
value of 13-03(P.286). It is recommended to gradually
increase the set value based on the increment of 1.

Vibration inhibition factor
 In practical applications, the frequency range where the vibration occurs is usually lower than or higher than half of
the rated frequency of the motor to distinguish as "low frequency vibration " or "high frequency vibration ",
that is:
If the rated frequency of the motor nameplate is 50Hz,
If the frequency of oscillation is lower than 25Hz, it is considered as "low frequency vibration:".
If the frequency of oscillation is higher than 25Hz, it is considered to be "high frequency vibration ".
Note: The motor current will fluctuate in a certain operating frequency band under Normal duty conditions, which may
cause slight vibration of the motor. If it does not cause application impact, it can be ignored.
