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
MD37250 MS_ASSIGN_MASTER_SPEED_CMD ≠ 0
●
Activation of a master-slave coupling via
MD37262 MS_COUPLING_ALWAYS_ACTIVE=0
●
The coupling is open.
Typical sequence of operations
Action
Effect/comment
•
Approach coupling position
Each axis moves to the coupling position.
•
Close coupling mechanically
Both axes are mechanically coupled to one
another.
•
Request to close the coupling
PLC interface signal "Master/slave on"
V380x 5000.7 is set.
•
Read back coupling state
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.
•
Move master-slave grouping
The master axis is moved.
