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.
