Spindle orientation through initiator with Marker M2501
The spindle can also be oriented through an initiator. This requires that Marker M2501 be set by the
PLC. This marker activates a spindle rotation at the speed defined in machine parameter MP3520.0
and in the direction of rotation defined in Marker M2656. If Marker M2501 is reset by the PLC (e.g.
through initiator), the spindle stops. The position value is shown in the status window. This method
can also be used to a enable a jog-mode spindle orientation.
