Upper Bound of Output Frequency
Unit: 0.1Hz
Settings 0.10 Hz to 400.0 Hz Factory Setting: 400
The Upper/Lower Bounds help prevent operation error and machine damage.
If the Upper Bound of Output Frequency is 50Hz and the Maximum Output Frequency is 60Hz,
the Maximum Output Frequency will be limited to 50Hz.
Setting of this parameter must be equal to or greater than the Lower Bound of Output
Frequency (Pr.37).
Pr.37
Lower Bound of Output Frequency
Unit: 0.1Hz
Settings 0.00 Hz to 400.0 Hz Factory Setting: 0 Hz
Setting of this parameter must be equal to or less than the Upper Bound of Output Frequency
If the Lower Bound of Output Frequency is 10Hz, and the Minimum Output Frequency (Pr.08)
is set at 1.0Hz, then any command frequency between 1-10Hz will generate a 10Hz output
from the drive.
