Lower output frequency will limit the min. output frequency of drive. When drive frequency command
or feedback control frequency is lower than this setting, drive output frequency will limit by the lower
limit of frequency.
When the drive starts, it will operate from min. output frequency (Pr.01-07) and accelerate to the
setting frequency. It won't limit by lower output frequency setting.
The setting of output frequency upper/lower limit is used to prevent personal misoperation, overheat
due to too low operation frequency or damage due to too high speed.
If the output frequency upper limit setting is 50Hz and frequency setting is 60Hz, max. output
frequency will be 50Hz.
If the output frequency lower limit setting is 10Hz and min. operation frequency setting (Pr.01-07) is
1.5Hz, it will operate by 10Hz when the frequency command is greater than Pr.01-07 and less than
10Hz. If the frequency command is less than Pr.01-07, the drive will be in ready status and no
output.
If the frequency output upper limit is 60Hz and frequency setting is also 60Hz, only frequency
command will be limit in 60Hz. Actual frequency output may exceed 60Hz after slip compensation.
