Inputs

MC_CamIn

This FB serves to execute a provided cam.

For clutching to the master axis, the slave axis carries out a compensating movement.

Various modes are available for the clutch-in process.

For master and slave axis, an extension/compression and offset can be activated.

Only the slave axis is moved with this FB, not the master axis.

Outputs

Name Data type	Value/meaning
InSync BOOL	TRUE	Slave and master axis are synchronised, the work curve is executed.
