Function Manual, 11/2012, 6FC5397-1CP10-5BA0
Compensation table 1 (table index = 0) describes the reaction of axis X1 on axis X1 (sine of
the position-dependent tilting angle β(X1)).
Compensation table 2 (table index = 1) describes the reaction of axis Z1 on axis X1 (linear).
In table 1, the multiplication of table 1 (index = 0) with table 2 is to be selected:
$AN_CEC_MULT_BY_TABLE[0] = 2

Special features of interpolatory compensation
Measurement
The "Measurement" function supplies the compensated actual position values required by
the machine operator or programmer.
TEACH IN
The "TEACH IN" function also uses compensated actual position values to determine the
positions to be stored.
Software limit switches
The compensated actual position values are also monitored at the software limit switches.
Position display
The position actual-value indicator in the machine coordinate system shows the actual
position value programmed for the axis.
On the "Service Axes" screen in the "System" → "Service Display" operating area, the actual
position value determined by the measuring system plus the sum of the backlash
compensation and leadscrew error compensation is displayed (= actual position value for
measuring system 1).
