3-18 Relative Scaling Reference Resource
Default value: [0] No function Parameter type: Option
Setup: All setups Conversion index: –
Data type: Uint8 Change during operation: True
Select a variable value to be added to the fixed value (defined in parameter 3-14 Preset Relative Reference). The sum of the fixed and
variable values (labeled Y in Figure 23) is multiplied by the actual reference (labeled X in the following illustration). This product is then
added to the actual reference (X+X*Y/100) to give the resulting actual reference.
 NOTICE
This parameter cannot be adjusted while the motor is running.
