# ID 20476

A slave axis is not allowed to be programmed as slave axis repeatedly.
Description | When defining a coupling group, it is detected that a slave axis is already programmed as slave axis in another coupling pair. This inter coupling pair relation is not permissible, because a slave axis may only be assigned to one master axis.

Example:

Wrong:

N10 G00 X0 Y0 Z0

N20 #SET AX LINK[1,C=X, C=Y, B=Y]

:

N1000 M30

Correct:

N10 G00 X0 Y0 Z0

N20 #SET AX LINK[1,C=X, B=Y]

:

N1000 M30

Response | Class | 2 | Abort NC program processing.
Solution | Class | 3 | Check and modify NC program. A slave axis may only be assigned to one master axis. All additional coupling pairs with that slave axis have to be removed from coupling group. For further information see [PROG// Section: Synchronous mode].
Parameter | %1: | Logical axis number [-]
Logical number of slave axis
Error type | 1, Error message from NC program.
