Output Frequency Lower Limit

Settings
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.
