This property stores an offset to the actual axis position. It is used to change the way the values of POSITIONCOMMAND and POSITIONFEEDBACK appear. If PCMD/actual refers to the actual position command being sent to the drive, and PCMD/user refers to the value of POSITIONCOMMAND being presented to you, DISPLACEMENT relates them as follows:
PCMD/user = PCMD/actual - DISPLACEMENT
and similarly for POSITIONFEEDBACK:
PFB/user = PFB/actual - DISPLACEMENT
Before the value of DISPLACEMENT is changed, it must first be set to zero.
Short form
<axis>.Disp
Syntax
<axis>.Displacement = <expression>
?<axis>.Displacement
Availability
All versions
Type
Double
Range
±MaxDouble
Units
User position units, as given by <axis>.POSITIONFACTOR.
Default
0
Scope
Configuration, Task or Terminal
Limitations
The axis must be disabled before DISPLACEMENT is changed.
To set the value within a task, the axis must be attached to that task (using the ATTACH command).
Examples
Axis1.Displacement = Axis.Pcmd
