PS.00 can only be written if the modulation is switched off, Sy.50 can always be written. The synchronous mo-
dule must be activated by an input. Which input is to be used is determined via parameter PS.02 "posi / sync
input selection".
7.12.3.5 Synchronous mode / activation and synchronization
7.12.3.5.1 Principle
With the activation of the synchronous module, the relation between master position and slave position is es-
tablished.
Activation means: - the synchronous mode is selected in parameter PS.00,
- modulation is enabled,
- the digital input for activation of the synchronous operation is set.
The starting synchronisation begins at the time of activation.
Attenti-
on:
Gear factor changes, angle correction or similar may not be exe-
cuted during the synchronisation.
The synchronous module is not deactivated by switching of the modulation. The angle difference is continuous-
ly calculated, and, after again switching on the modulation, a synchronisation with ramps is always carried out
(independent of the type of initial synchronisation).
The synchronisation type at activation of the synchronous running is determined by the adjustment of "syn-
chronous running / starting ramp (oP.28)" in parameter PS.00 "pos/syn mode" and by parameter PS.05 "start
offset" .
7.12.3.5.2 Synchronization at limit
The starting ramp must be deactivated for the synchronization at torque limit.

Synchronous running /
starting ramp (oP.28)
0: off
No starting ramp for synchronisation at the start of the synchro-
nous running.
Furthermore value 0 must be entered in parameter PS.05 "start offset".
This parameterization is only reasonable if master and slave rotate with the same speed at the start of the
synchronous operation, thus a synchronisation is unnecessary. If the speeds are different, the synchronisation
occurs in the following manner:
