DrvScaling function block is used to scale the speed or torque reference to the drive based on the maximum values defined.

Function block “DrvScaling” can be used to scale the variables from fieldbus equivalent values to values used in the program. Fieldbus variables are given in fieldbus equivalent values as INT values. With the scaling a conversion from INT (fieldbus) to REAL (program) and vice versa is performed. Reference1 and Actual Value1 (speed) are mostly given in the range of -20000 ... +20000. Reference2 and Actual Value2 (torque) are mostly given in the range of 0 ... +10000.
