Compensation (K3)
11.3 Interpolatory compensation
Turning, Milling, Nibbling
222 Function Manual, 11/2012, 6FC5397-1CP10-5BA0
$AN_CEC_MAX[0] = 360.0
$AN_CEC_IS_MODULO[0] = 1
Note
Table parameters containing position data are automatically converted when the scaling
system is changed (when the setting in the following machine data is altered):
MD10240 SCALING_SYSTEM_IS_METRIC (basic system metric)
The position information is always interpreted in the current measuring system.
Conversion must be implemented externally.
Where the following setting applies:
MD10260 CONVERT_SCALING_SYSTEM = 1 (basic system switchover active),
the scaling system can be configured using the following machine data:
MD32711 CEC_SCALING_SYSTEM (scaling system for sag compensation)
Table example
The following example shows the compensation table for sag compensation of axis Y1.
Depending on the position of the Y1 axis, a compensation value is applied to the X1/Z1 axis.
