Special features of interpolatory compensation

Measurement
The "Measurement" function supplies the compensated actual positions (ideal machine)
required by the machine operator or programmer.
TEACH IN
The "TEACH IN" function also uses compensated position values to determine the actual
positions to be stored.
Software limit switch
The ideal position values (i.e. the position actual values corrected by the MSEC and
backlash compensation functions) are also monitored by the software limit switches.
Position display
The position actual-value display in the machine coordinate system shows the ideal
(programmed) actual position value of the axis (ideal machine).
The position actual value determined by the measuring system plus the sum of MSEC and
backlash compensation (= position actual value, measuring system 1/2) is displayed the
"axis/spindle" service display (operating area "Diagnosis")
Compensation value display
The following compensation values are also output in the "Axis/spindle" service display
(operating area "Diagnosis"):
● Absolute compensation value measuring system 1 or 2
● Compensation, sag + temperature
Reference point loss
If the reference point of the basic axis is lost (DB31, ... DBX60.4 or 60.5 = 0), then MSEC
and sag compensation functions are deactivated in the axes involved. These are
automatically reactivated when the reference point is reached.
Access protection
Currently there is no protection against access to the compensation tables.
Extended Functions
Function Manual, 03/2013, 6FC5397-1BP40-3BA1
Displayed value corresponds to the total compensation value calculated from MSEC and
backlash compensation associated with the actual position of the axis (measuring system
1 or 2).
Display value is the sum of the compensation values from sag compensation and
temperature compensation for the actual position of the axis.
