Chapter 7 Basic Functions
Skip frequency operation
Group
Function group 2
Set H10 to 1 (using skip frequency function).
The operating frequency can‟t be set at H11~H16. The frequency value of low-number parameter can
not be higher that of high-number parameter.
Skip frequency is settable within max frequency (F21) and start frequency (F23).

The skip-frequency function is to prevent that motor operates in the range of resonance frequency in the
mechanical system. However, during acceleration or deceleration the motor can run through the skip-
frequency range but can‟t run at a certain speed.
When Accel is made, if the frequency setting value (setting via voltage, current, RS-485 communication or
keypad) is within the skip-frequency range, the frequency setting shall maintain at the skip-frequency low
limit, it starts to be increased beyond the range.
When Decel is made, if the frequency setting value (setting via voltage, current, RS-485 communication or
keypad) is within the skip-frequency range, the frequency setting shall maintain at the skip-frequency low
limit, it starts to be decreased beyond the range.
