Frequency Limit Using Upper and Lower Limit Frequencies - Setting Details
Code Description
Ad.24 Freq Limit
The initial setting is 0(No). Changing the setting to 1(Yes) allows the setting of
frequencies between the lower limit frequency (Ad.25) and the upper limit
frequency (Ad.26). When the setting is 0(No), codes Ad.25 and Ad.26 are not
visible.
Ad.25 Freq Limit Lo,
Ad.26 Freq Limit Hi
Set upper and lower frequency limits. All frequency selections are restricted to
frequencies from within the upper and lower limits.
This restriction also applies when you in input a frequency reference using the
keypad.
Frequency Jump
Use frequency jump to avoid mechanical resonance frequencies during acceleration and
deceleration. Operation frequencies cannot be set within the pre-set frequency jump band.
When the frequency reference value (voltage, current, RS-485 communication, keypad setting,
etc.) is within a jump frequency band , the frequency will be maintained at the lower limit value of
the frequency band. When the frequency reference increases to a speed above the frequency jump
band, the inverter will accelerate to the corresponding speed based on the existing frequency
reference.
