MC_CamOut

Commanding of a MC_CamOut FB releases coupling of the slave axis to the master axis that has been specified via a cam. The current speed of the slave is retained (endless motion).

Parameters of the FB

VAR_IN_OUT
	Slave	AXIS_REF	Axis reference to the slave axis.
VAR_INPUT
	Execute	BOOL	Start to disengage the slave from the master.
VAR_OUTPUT
	Done	BOOL	Disengaging completed.
	Error	BOOL	Indicates if an error has occurred.
	ErrorID	WORD	Error identification.

Behavior of the FB

Release of coupling of the slave axis to the master axis can only be commanded if the slave axis is in the ‘Synchronized Motion’ state. If this is not the case, the ‘Error’ output is set to FALSE and ‘ErrorID’ indicates an error value that designates the state the axis is currently in.
Mention is made here once again of the (idiosyncratic) definition of the PLCopen standard to the effect that the commanded slave axis remains at its momentary speed after cancellation of coupling. Therefore, it does not necessarily stop.
The function block is retriggerable. Therefore, it can send a command again in the active state.
