Output Frequency Lower Limit Unit: 1
Settings 0 to 100% Factory Setting: 0
The Upper/Lower Limits are to prevent operation errors and machine damage.
If the Output Frequency Upper Limit is 50Hz and the Maximum Output Frequency is 60Hz, the Output
Frequency will be limited to 50Hz.
If the Output Frequency Lower Limit is 10Hz, and the Minimum Output Frequency (Pr.01-05) is set to 1.0Hz,
then any Command Frequency between 1.0-10Hz will generate a 10Hz output from the drive.
This parameter must be equal to or less than the Output Frequency Upper Limit (Pr.01-07).
The Output Frequency Lower Limit value = (Pr.01-00 * Pr.01-08) /100.
