Configuring a coupling
Static assignment
For a speed setpoint coupling and torque equalization control, the static assignment of master
and slave axis is defined separately in the following machine data:
•
Speed setpoint coupling
MD37250 $MA_MS_ASSIGN_MASTER_SPEED_CMD[<slave axis>] =
<machine axis number of the master axis for the speed setpoint coupling>
•
Torque equalization control
MD37252 $MA_MS_ASSIGN_MASTER_TORQUE_CTR[<slave axis>] =
<machine axis number of the master or slave axis for torque equalization control>
See Chapter "Tension torque [Page 515]"
Dynamic assignment
The assignment of master and slave axes can be dynamically changed using the following
program commands.
Defining the assignment
Assignment of one or several slave axes to a master axis:
MASLDEF (<slave axis_1>, <slave axis_2>, ..., <master axis>)
The assignment is kept even after an operating mode change, reset and end of part program:
Deleting an assignment
Deleting an assignment of one or several slave axes to their particular master axis:
MASLDEL (<slave axis_1>, <slave axis_2>, ...)
An active coupling is first implicitly opened before deleting the assignment.
Axis assignment for speed setpoint coupling and torque equalization control
For the speed setpoint coupling, the slave axis refers to the master axis specified when
defining the assignment (MASLDEF).
The axis to which the slave axis refers for torque equalization control is defined in the
following machine data:
MD37253 $MA_MS_FUNCTION_MASK[<slave axis>], bit 1 = <value>
<value>
For information on this, see Chapter "Tension torque [Page 515]"

Description
0
In the case of dynamic assignment (MASLDEF), the slave axis for the torque equalization
control – as well as for speed setpoint coupling – refers to the master axis of the master-
slave group.
1
In the case of dynamic assignment (MASLDEF), the slave axis for the torque equalization
control refers to the axis, master or slave axis of the master-slave group specified in
machine data:
MD37252 $MA_MS_ASSIGN_MASTER_TORQUE_CTR<slave axis> = <axis>
