Freq. Up setting
Freq. Down setting
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 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 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.
