7.6.74.6 Fault indications
Fault indications for the synchronization via system bus
Fault Cause Remedy
P16
Controller was enabled in an unsynchronized
state (SYNC1-STAT = LOW)
Enable controller only after SYNC1-STAT = HIGH
The time between two sync telegrams is
faulty
C0362 displays the period between two sync telegrams.
l
Set the time in C1121/1 to the time in C0362.
l
Adapt the time of the sync telegram from the master
Fault indications for the synchronization via terminal
Fault Cause Remedy
P16
Controller was enabled in an unsynchronized
state (SYNC1-STAT = LOW)
Enable controller only after SYNC1-STAT = HIGH
No sync signal Connect sync signal to terminal X5/E5
The period of the sync signal is not a multiple
of 1 ms
Adapt period
Sync window too small Adapt C1123/2 to the ratios
7.6.74.7 Configuration examples
Configuration example CAN-SYNC
Maintain the following sequence during the commissioning:
Step Where Operation
1. - Commission controller and system bus without FB SYNC1
2. - Inhibit controller
3. CAN master Define telegram sequence
1. Send new setpoint to all slaves
2. Send SYNC telegram
3. All slaves must respond
4.
CAN slaves
Enter FB SYNC1 in the first position of the processing table
5.
Parameterize the signal assignment of the inputs at FB SYNC1
6. Select C1120 = 1 (sync mode for FB SYNC1)
7. CAN master Start communication, send sync telegrams
8.
CAN slaves
FB SYNC1 (CAN SYNC-CYCLE)
l
Request cycle time of the SYNC telegram from the master under C0362
9. FB SYNC1 (SYNC CYCLE)
l
Set C1121 according to the time of the sync telegrams from the control
l
Set C1121

C0362
10. Parameterize the monitoring function P16 under C1290
11. Connect output signals of SYNC1 to the desired inputs of the corresponding FB
12. Via FB DIGOUT
l
detect signal from SYNC1-STAT
13. When SYNC1-STAT = HIGH, enable controller
