Synchronization of the spindle M-functions

Synchronization between the interpolator and the relevant spindle is performed directly, i.e. the acknowledgement of M03, M04 (speed reached) and M05 (speed zero) is performed by the spindle itself. Bit PLC_INFO which can be set in addition to the existing synchronization modes [1]-3 determines whether the PLC is also to be informed for acknowledgement. Note the following in this case:

In the case of velocity-controlled spindles, the PLC is also informed for acknowledgement automatically on a general basis in the case of each spindle M-function. It is thus not required to also set the PLC_INFO bit.

It is practical to use the PLC_INFO bit in the case of position-controlled spindles. In this case, the PLC_INFO bit can be set for each spindle M-function in addition to the synchronization mode, thus causing the PLC to be informed for acknowledgement.

Spindle S1 shall be a position controlled spindle.
