Parameter
4.37
Slip compensation coefficient (P.89)
P.89 “Slip compensation coefficient”
● We can make the speed of the motor, which runs with rated current, to be much closer to the setting
speed by setting this parameter properly.
● This function is valid in V/F curve. It means P.300 must be set to 0.

4.38 Frequency jump (P.91~P.96)
P.91~P.96 “Frequency jump”
● To avoid the system mechanical resonance frequency, 3 sets of jump frequencies are presented,
namely, the first by P.91 and P.92, the second by P.93 and P.94 and the last by P.95 and P.96.

<Setting>
• For example: Suppose that P.91 = 45 and P.92 = 50
If the target frequency
≦
45Hz, the steady output frequency = the target frequency.
If 45Hz < target frequency
≦
50Hz, the steady output frequen
= 45Hz.
If 50Hz < target frequency, the steady output frequency = the target frequency.
Note: 1. During acceleration/deceleration, the output frequency of the inverter will still pass through the jump
frequency.
2. If P.91=9999 or P.92=9999, the first set of frequency jump is invalid.
If P.93=9999 or P.94=9999, the second set of frequency jump is invalid.
If P.95=9999 or P.96=9999, the third set of frequency jump is invalid.
3. If P.187=1, P.91~P.96 are in the range of 0~1000Hz.
