Skip frequency 7.7.3
Group Code Parameter Name Setting Range Default Unit
Function group 2
H10 [Skip frequency select] 1 0 - 1 0
H11 [Skip frequency low limit 1] - 0.1 - 400 10.00 Hz
- -
H16 [Skip frequency low limit 3] - 0.1 - 400 35.00 Hz
Set H10 to 1.

Run frequency setting is not available within the skip frequency range of H11-H16.

Skip frequency is settable within the range of F21
– [Max frequency] and F23 – [Start 
frequency].
►
When it is desired to avoid resonance attributable to the natural frequency of a
mechanical system, these parameters allow resonant frequencies to be skipped. Three
different areas of [Skip frequency High/Low limit] can be set with the skip frequencies
set to either the top or bottom point of each area. However, during acceleration or
deceleration, the run frequency within the set area is valid.
►
In the case of increasing frequency setting as shown above, if frequency set value
(Analog setting via voltage, current, or digital setting via keypad) is within the range of
Skip frequency, it maintains Skip freq RS485 communication, frequency low limit value.
If the set value is outside the range, it increases the frequency.
►
In the case of decreasing frequency setting, if frequency set value (Analog setting via
voltage, current, RS485 communication, or Digital setting via keypad) is within the
range of Skip frequency, it maintains Skip frequency high limit value. If the set value is
outside the range, it decreases the frequency.
