Synchronous start/stop
For MOVIDRIVE
®
synchronous operation, the following mixed mode is possible:
•
Master is less dynamic or as dynamic as the slave
•
Master is an incremental encoder
•
Brake function OFF:
No controller inhibit (DI00 "/CONTROLLER INHIBIT" = "1") and no ENABLE (DI03 =
"0")
→
slave is at a standstill at speed 0 subject to speed control
No controller inhibit (DI00 "/CONTROLLER INHIBIT" = "1") and ENABLE (DI03 = "1")
→
slave synchronizes itself with the master position.
•
Brake function ON:
When both master and slave are at a standstill at speed 0, the slave brake is applied.
The following table lists the settings or cable connections for the above master/slave
combinations with regard to synchronous starting / stopping and activated cable-break
monitoring.
The master and slave(s) must be able to start / stop synchronously in both options. This
is the prerequisite for correct operation. As a result, combinations in which the master is
more dynamic than the slave are not permitted.

Comment
Cable-break monitoring:
DO01 = "MOTOR STANDSTILL"
Synchronous start/stop:
DO02 = "OUTPUT STAGE ON"
Cable-break monitoring:
DI terminal = "DRS MAST. STOPPED"
Synchronous start/stop:
DI terminal = "DRS SLAVE START"
Enable slave permanently.
Binary outputs DO01 and
DO02 are no longer available
on the master.
When the brake function is activated, the slave terminal "DRS SLAVE START" must
always be programmed and wired up. This also applies when the master is only an
incremental encoder; in this case, an external controller must give the signal "DRS
SLAVE START."
When the brake function is deactivated, the position is held subject to position control
when the signal "DRS SLAVE START" is revoked or if the drive reaches the stop area
(P510).
