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.
