Compensation value display
The "Service Axes" screen also shows the following compensated actual position values:
Service display axes
Absolute compensation value for
measuring system 1
Sag compensation value
Reference point loss
If the reference point of the basic axis is lost (IS "Referenced/synchronized 1" V390x 0000.4
= 0), the LEC and sag compensation functions are deactivated in the affected axes. When
the reference point is reached, these compensations are automatically reactivated.
Setting servo enables
As a result of the compensation relationship, a traversing motion by the basic axis may also
cause the compensation axis to move, making it necessary for servo enables to be set for
these axes too (PLC user program). Otherwise, the compensation function will be restricted.
Traversing signal output
The traversing signals in the compensation axis are output when compensation is
activated/deactivated, as well as each time the number of active compensation tables
changes.
Any change in the compensation value caused by the basic axis motion does not result in
traversing signals being output in the compensation axis.

Meaning
Value displayed is the total compensation value calculated from
"Leadscrew error compensation" and "Backlash compensation"
for the current actual position of the axis (measuring system 1).
Value displayed is the total compensation value calculated from
"Sag compensation" for the current actual position of the axis.
