Supplementary conditions

Compensated actual position
The following functions are based on the compensated actual position:
● Measurement
● Teach In
● Software limit switch
Displaying the actual position
The actual position of the axis without compensation (ideal machine) is displayed in the actual
position display in the machine coordinate system.
The actual position of the axis with compensation (MSEC and backlash compensation) is
displayed in the service display "Axis/spindle" ("Diagnostics" operating area).
Displaying the compensation values
The following compensation values are also output in the "Axis/spindle" service display
(operating area "Diagnosis"):
● "Absolute compensation value measuring system 1" or 2
The value displayed is the sum of the compensation values of MSEC, obtained from the
actual position of the basic and compensation axis, and backlash compensation.
● Compensation, sag + temperature
The value displayed is the sum of the compensation values of sag and temperature
compensation, obtained from the actual position of the basic and compensation axis.
