Note
For the slave axis, the actual value can be synchronized to the same value of the master
axis using
order to set the actual value of the non-referenced slave axis to the value of the master/axis
with power on. Then the coupling is permanently re-established.
The permanent master/slave coupling is activated using the MD setting
MD37262 $MA_MS_COUPLING_ALWAYS_ACTIVE = 1 – and this has no effect on the
language commands of the temporary coupling.
Coupling behavior for spindles!
For spindles in the open-loop speed controlled mode, the coupling behavior of

MD37263 $MA_MS_SPIND_COUPLING_MODE.
For the default setting with MD37263 = 0, the slave axes are coupled-in and coupled-out
only when the axes involved are at standstill.
For MD37263 = 1, the coupling instruction is immediately executed and therefore also the
motion. For

This instruction is executed directly for spindles in speed control mode.
The slave spindles rotating at this instant keep their speeds until a new
speed is programmed.
Definition of a master/slave group from the part program. Beforehand, the
definition was made exclusively using machine data.
The instruction cancels assignment of the slave axes to the master axis
and simultaneously opens the coupling, like MASLOF.
The master/slave definitions specified in the machine data are kept.
MASLOFS can be used to automatically brake slave spindles when the
coupling is opened.
For axes and spindles in the positioning mode, the coupling is only closed
and opened at standstill (zero speed).
. To do this, the permanent/slave coupling must be briefly switched-out in
