User scaling

The transfer function of the user scaling for the analog outputs is as follows:

 

YS = GS * XS + OS

YS : Output value after the user scaling

XS : Output value before the user scaling

GS : Gain

OS : Offset

Enabling user scaling

The user scaling is disabled in the factory. It can be enabled individually for each channel. To do this, set the corresponding CoE parameter to TRUE:
