●
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.

●
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.

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 frequency = 45Hz.
If 50Hz < target frequency, the steady output frequency = the target frequency.
