Close coupling via the PLC

This application allows you to close or separate a master-slave coupling between the
machine axes AX1=Master axis and AX2=Slave axis during operation.
Preconditions
● One configured master axis
● Activation of a master-slave coupling via
● The coupling is open.

Speed/torque coupling, master-slave (TE3)
Effect/comment
Each axis moves to the coupling position.
Both axes are mechanically coupled to one
another.
PLC interface signal "Master/slave on"
V380x 5000.7 is set.
When the axis is at a standstill, the coupled slave
axis sets PLC interface signal "Master/slave
active" V390x 5000.7 and clears "Position
controller active" V390x 0001.5.
Wait for checkback signal.
The master axis is moved.
