Response on activation/deactivation

Activating/deactivating during axis standstill
Activation/deactivation is not active until the axis next comes to a standstill. If the
specification is changed, the sequence is the same as for axis replacement. The coupling is
closed when the axis comes to a standstill. The coupled axes must be in feedback control
mode.

Block stepping is halted for
time, the associated channel operating message "Master-slave switchover active" is
displayed on the user interface.
Activation/deactivation during motion
Activation/deactivation of the coupling in motion has been implemented only for spindles in
speed control mode. For axes and spindles in positioning mode, switchover is still carried out
when the axis is at a standstill.
Activation during motion
The coupling procedure at different speeds is divided into two phases.
Phase 1
Closure of the coupling is requested with interface signal "Master/slave on" (V380x 5000.7).
The slave spindle accelerates or decelerates along the ramp with the dynamic response
available to it until it reaches the setpoint speed of the master spindle.
When the setpoint speed is reached, the coupling is closed and IS "Coupling active"
(V390x 5000.7) is set.
If the master spindle is accelerated during the coupling process, the first phase is extended
according to the existing difference in dynamics between the master and slave spindles.
