Behavior during POWER ON, ...

Power on
No coupling is active at power ON. Coupling modules are not available.
RESET
The behavior on RESET can be set separately for each coupling module (see CPMRESET).
The coupling can be activated, deactivated or the current state can be retained.
Mode change
The coupling remains active during a mode change. The coupling is suppressed (not
deselected!) only in JOG-REF mode when referencing a following axis.
Reference point approach
G74 of the following axis is not possible with an active coupling. An alarm is output.
If the JOG-REF mode is selected and the following axis is traversed, the coupling is
suppressed. The coupling is only performed after JOG-REF mode is cancelled.
SERUPRO
The SERUPRO procedure will simulate the generic coupling and provide values for a restart.
With axial couplings, the simulation always assumes a setpoint coupling, which means, when
there is an actual value coupling, this is switched to setpoint coupling during the SERUPRO
procedure. This can mean that the simulation is not performed correctly.
Further deviations from the real procedure can occur due to increased simulation speed and
canceled axis dynamics limitations.

Disturbance characteristic

5.5.11.1

Rapid stop

Function
The rapid stop stops the axis / spindle without ramp, i.e. the velocity setpoint value is
specified as zero. This default applies the brakes at the current limit. The servo enable is
retained.
