Output Frequency Lower Limit
Default: 0.00
Settings 0.00–599.00 Hz
Use the upper and lower limit output frequency setting to limit the actual output frequency. If the
frequency setting is higher than the upper limit (Pr.01-10), the drive uses the upper limit frequency.
If output frequency is lower than lower limit (Pr.01-11) and frequency setting is higher than
minimum frequency (Pr.01-07), the drive uses the lower limit frequency. Set the upper limit
frequency > lower limit frequency (Pr.01-10 setting value must be > Pr.01-11 setting value).
The upper output frequency limits the maximum output frequency of the drive. If frequency setting
is higher than Pr.01-10, the Pr.01-10 setting limits the output frequency.
When the drive starts the slip compensation function (Pr.07-27) or PID feedback control, the drive
output frequency may exceed frequency command but is still limited by this setting.
Related parameters: Pr.01-00 Maximum Operation Frequency
.
The lower output frequency limits the minimum output frequency of the drive. When the drive
frequency command or feedback control frequency is lower than this setting, the lower limit of the
frequency limits the drive output frequency.
When the drive starts, it operates from the minimum output frequency (Pr.01-07) and accelerates
to the setting frequency. It is not limited by the lower output frequency settings.
Use the output frequency upper and lower limit settings to prevent operator misuse, overheating
caused by operating at a too low frequency, or damage caused by excessive speed.
If the output frequency upper limit setting is 50 Hz and frequency setting is 60 Hz, the maximum
output frequency is 50 Hz.
If the output frequency lower limit setting is 10 Hz and the minimum operation frequency setting
(Pr.01-07) is 1.5 Hz, the drive operates at 10 Hz when the frequency command is higher than
Pr.01-07 and less than 10 Hz. If the frequency command is less than Pr.01-07, the drive stays in
ready status with no output.
