When the synchronisation via the terminals X5/E4 and X5/E5
(C0532 = 2) is activated, these terminals must not contain any
other signal connections.
When selecting a basic configuration via C0005, the terminals
contain a basic setting.
Selection of synchronisation
C0532 = 1 (zero pulse) The synchronisation is performed on the zero track of the
digital frequency input X9 and the zero track of the feedback
system set under C0490.
C0532 = 2 (touch probe) The synchronisation is performed using the terminals X5/E4
(actual pulse) and X5/E5 (setpoint pulse).
Touch probe initiators can have delay times which cause a speed−dependent
phase offset.
Set the correction for the phase offset under C0429.

The correction value for the phase offset can be obtained from the data
sheet of the initiator, or contact the manufacturer.
Synchronisation modes
C0534 Synchronisation mode Note
0 Inactive Function inactive
1 Continuous synchronisation with
correction in the shortest possible way
2 Continuous synchronisation with
correction in the shortest possible way
After a LOW−HIGH signal to
DFSET−0−pulse, the zero track is
synchronised once
10 One synchronisation. A phase deviation is
corrected in the shortest possible way.
11 One synchronisation. A phase deviation is
corrected in CW direction.
12 One synchronisation. A phase deviation is
corrected in CCW direction.
13 Single synchronisation. A phase difference
is determined between setpoint pulse and
actual pulse and is corrected to the
corresponding direction of rotation
according to the sign.
ƒ During synchronisation, DFSET−ACK is set to HIGH.
 Note!
Drive synchronisation is only reasonable if the controller is
operated with incremental encoder feedback and the calculated
following error is used for correcting the speed setpoint. The
following error is output to DFSET−PSET.
