8.6.3 Axis synchronisation via terminal X6/DI1
The transmission paths for the sync signal and the process data are separated.
ƒ The process data are transmitted via the CAN interface X4.
ƒ The sync signal is injected via the digital input X6/DI1.
)
Note!
If synchronisation takes place via X6/DI1 terminal, the control configuration of
the "Drive PLC Developer Studio" (DDS) must not only comprise the
SB CAN_Synchronization (
¶ 281) but also the SB DIGITAL_IO. (¶ 343)
Please observe the following sequence during commissioning:
Device Step Description
All devices 1. Commission the controller and the CAN bus.
2. Inhibit the drive controllers.
l Press the <F9> key in GDC.
^ 131
Slaves 3. Connect "CANSync−InsideWindow" with
digital output.
4. Connect the sync signal of the master to
terminal X6/DI1.
Slaves 5. C1120 = 2 Synchronisation through sync signal via
terminal X6/DI1 (DigIn_bIn1_b) is active.
Slaves 6. C0366 = 1 (Lenze setting) CAN sync reaction:
l Slaves respond to sync telegram.
Master 7. Start communication/send sync signals.
Slaves 8. Read C0362 from the master. Retrieve cycle time of the sync signal from
the master.
9. Set C1121 according to C0362 of the master. Adjust the time distance of the sync signal to
be received to the cycle time of the master.
10. Set C1123. Set optimum size for the "time slot".
l If the sync signal "jitters" heavily ( ^ 167),
increase "time slot".
11. Enable the controller via the signal
"CANSync−InsideWindow" applied to the
digital output.
Synchronisation monitoring:
l If "CANSync−InsideWindow" = TRUE,
enable the controller.
