User scaling

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

 

YS = GS * ( XS – OS )

YS : Measured value after the user scaling

XS : Measured 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 "Enable user scale" to TRUE:

Channel

"Enable user scale"

1

0x8010:01

2

0x8020:01

Setting the scaling coefficients

Set the scaling coefficients via the CoE parameters "User scale offset" and "User scale gain":

Channel

"User scale offset"

"User scale gain"

1

0x8010:11

0x8010:12

2

0x8020:11

0x8020:12
