EDSVS9332S−EXT EN 2.0
3.2.63.7 Configuration examples
Configuration example CAN−SYNC
Observe the following order for commissioning:
Step Where Operation
1. − Commission controller and system bus without FB SYNC1
2. − Inhibit controller
3. CAN master Define the sequence of the telegrams
1. Send new setpoint to all slaves
2. Send sync telegram
3. All slaves must respond
4. CAN slave drives Enter FB SYNC1 into the first position of the processing table
5. Parameterise 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 slave drives FB SYNC1 (CAN SYNC−CYCLE)
·
Retrieve cycle time of the SYNC telegram from the master via C0362
9. FB SYNC1 (SYNC CYCLE)
·
Set C1121 according to the time interval of the sync telegrams from the control
·
Set C1121 w C0362
10. Parameterise the monitoring function P16 via C1290
11. Connect the output signals of SYNC1 with the required inputs of the corresponding FB
12. Via FB DIGOUT
·
Detect signal of SYNC1−STAT
13. Only enable the controller when SYNC1−STAT = HIGH
Configuration example TERMINAL−SYNC
Observe the following order for commissioning:
Step Where Operation
1. − Commission controller without FB SYNC1
2. − Inhibit controller
3. Slave drives Enter FB SYNC1 into the first position of the processing table
4. Apply sync signal to terminal X5/E5
5. Parameterise the signal assignment of the inputs at FB SYNC1
6. Select C1120 = 2 (sync mode for FB SYNC1)
7. Sync master Start communication, send sync signals
8. Slave drives FB SYNC1 (SYNC CYCLE)
·
Parameterise the sync cycle time of the sending source via C1121
9. Parameterise the monitoring function P16 via C1290
10. Connect the output signals of SYNC1 with the required inputs of the corresponding FB
11. Via FB DIGOUT
·
Output signal of SYNC1−STAT
12. FB SYNC1 (SYNC WINDOW)
·
Enter the optimal size of the "time slot" via C1123/2
·
If the sync signal jitters strongly, increase the "time slot"
13. Only enable the controller when SYNC1−STAT = HIGH
3.2.63.8 Scaling
The signal at input is transmitted in a scaled form to SYNC1−OUT1.
Scaling formula:
SYNC1−OUT1 [rpm] + SYNC1−IN1 [inc] @
1875 rpm
2048 inc
The inputs SYNC1−IN2 and SYNC1−IN3 are not scaled. The FB transmits the data to SYNC1−OUT2
or SYNC1−OUT3 without any evaluation.
