Figure 2-2 Release axis clamp if MD36052 $MA_STOP_ON_CLAMPING = 'H01'
The part-program blocks N310 and N410 refer to the following programming example:
Optimized releasing of the axis clamp via travel command
If a clamped axis is to be traversed in continuous-path mode, a travel command is issued for the clamped axis in
the rapid traverse blocks (G0) immediately before the traversing block of the clamped axis. This way, the PLC
user program can release the axis clamp again in time. (The travel command is set a maximum of two rapid
travers blocks prior (including intermediate blocks) to retain the reference to the initiating part program block).
