What is the parameter(s) that controls a "minimum speed" without changing the velocity reference scaling on a PowerFlex 755TS?

This article provides information on how to set a minimum speed on a PowerFlex 755TS without having to change the scaling of the speed reference.

Port 10 Parameter 1900 sets the minimum speed (hz) of the PowerFlex 755TS in the forward direction.

Port 10 Parameter 1901 sets the minimum speed (hz) of the PowerFlex 755TS in the reverse direction.

 

 

Example:

If parameter 1900 ( Vel Low Lim Pos) was set to 40hz and then the drive is started, the minimum speed would be at 40hz regardless of the velocity reference being set lower. Once the velocity reference is greater than 40hz, the drive will following the velocity reference.
