Modulo rotary axes
●
For the slave axis, the actual value in the "System" menu, "Service Display" softkey,
exceeds 360 degrees even if modulo operation has been set for the axis using the
following machine data: MD30310 ROT_IS_MODULO
●
The automatic basic display and the service display do not show the actual value "Modulo
360°" until the coupling is deactivated.
Spindles
●
If a master-slave coupling is activated with spindles, the slave axis is in speed control
mode. In this case too, the actual value of the slave axis exceeds 360 degrees in the
service display. No modulo calculation is active. However, the value shown in the
automatic basic display is "Modulo 360°".
●
If the spindles are accelerated at the current limit, this may mean that no adjusting
reserves are left over in the coupled state for the torque compensation controller to use in
order to distribute the torque between the master and the slave as required.
●
The maximum master spindle chuck speed is to be configured as less than or equal to
that of the slave spindles: MD35100 SPIND_VELO_LIMIT
●
The axial velocity monitoring function should be adapted to the chuck speed:
MD36200 AX_VELO_LIMIT

Configuration
1.
Machine axis number of master axis for speed setpoint coupling
MD37250 MS_ASSIGN_MASTER_SPEED_CMD[AX2] = 1
2.
Master axis with torque distribution identical to master axis with speed setpoint coupling
MD37252 MS_ASSIGN_MASTER_TORQUE_CTR[AX2] = 0
3.
Parameter assignment for the master-slave coupling
MD37253 MS_FUNCTION_MASK = 1
4.
Permanent coupling
MD37262 MS_COUPLING_ALWAYS_ACTIVE[AX2] = 1
5.
Torque is injected in both the master and slave axes
MD37254 MS_TORQUE_CTRL_MODE[AX2] = 0
