Activate
If the “Flying S aw” function is set, synchronisation can be activated or deactivated by star ting c om-
mand records.
• Set synchronisation for the respective positioning record via the “Positioning record” dialog:
Synchronisation activated (Sync):
With synchronisation active, the current position of the master drive is switched onto the position set-
point value of the motor controller via the encoder at connection [X10] . The drive thus follows the
changes in position of the master drive.
Synchronisation is activated when positioning is started, if it was not already. If the master is not sta-
tionary when positioning starts, the offset that occ urs will be made up in a c ontrolled manner. The posi-
tioning speed used for this corresponds to the speed of the master plus the positioning speed entered
in the positioning record as an excessive increase in speed. The entries of the started positioning re-
cord are likewise used for the accelerations.
Synchronisation deactivated (No Sync):
Synchronisation is deactiv ated when positioning is started, if it was not already. Positioning starts with
the c urrent setpoint speed, that is, with the speed of the master. This results in controlled desynchron-
isation.
Synchronisation deactivated (Sync Out):
Synchronisation is deactiv ated when positioning is started, if it was not already. Positioning starts with
the c urrent synchronous positioning speed (rotational speed of the master). This results in controlled
desynchronisation.
Note
Observe the following:
When positioning with synchronisation is activated, the digital halt only stops the posi-
tioning record, but not necessarily the movement of the drive, since synchronisation
remains active!
Synch ronisation must be explicitly terminated by starting a new positioning record
without synchronisation or by using the digital input “Disconnect sync.”.
6.5.5 Scope of functions for cam discs (CAM)
The term “electronic cam disc” designates a pplications in which an input angle or an input position is
depicted through a func tion as an angle setpoint value or a setpoint position. These applications are
typically master-slave applications.
The CMM P-AS-...-M0 has the option of processing 16 cam discs each with 4 assigned cam tracks. The
CMM P-AS-...-M0 provides the following functionality for this purpose via FHPP:
– Slave with synchronisation operation onto external input with cam disc
– Virtual master (internal) with cam disc.
A requirement is the positioning mode operating mode (record selection or direct mode). Additional
information on parameterisation can be found in the Help for the CMMP-AS plug-in. For complete in-
formation on the c am disc func tion, see the special c am disc manual P.BE-CMMP-CAM-SW-....
