[FUN 25] selects the limits for the inverter operating
frequency. If [FUN 24] is set to ‘Yes’, the inverter
operates within the upper and lower limit setting.
The inverter operates at the upper or the lower limit
when the frequency reference is outside the
frequency limit range.
[Freq. limit: ‘Yes’]
n
Note: When setting the frequency below the low limit or
above the high limit, the drive will automatically ramp inside
the limited setting.
n
Note: When accelerating or decelerating, the output
frequency follows the normal acceleration and deceleration
rates.

To prevent undesirable resonance and vibration on
the structure of the machine, this function locks out
the resonance frequency from occurring.
Each jump frequency also has a bandwidth. This is a
span of the particular jump frequency selected. Three
different jump frequencies can be set. However,
there is only one bandwidth frequency available.
