FM 452 Electronic Cam Controller
C79000-G7076-C452-04
Operation:
The CPU is in the STOP mode. Open the VAT1 variable table and transfer the
control values.
Start the CPU (STOP > RUN-P). You can see how the actual position
(CAM.ACT_POS), the cam data (CAM.CAM_00_31) and the track signals
(CAM.TRACK_OUT) change. You should also observe the step number of the step
sequence (PROGDB.STEPNO).
When cam 4 is set (130 degrees), cams 1 and 2 are assigned new parameter
values that were specified in VAT1. You can see the modification in the VAT.
The program then waits for an external event. Transfer the prepared control values
from the VAT again (this time PROGDB.SWITCH is evaluated). The cam data
return to the previous values again.
After this run through, the step sequence has been processed, the step number is
-2, and simulation is stopped.
If you want to repeat the entire sequence again, restart the CPU (STOP > RUN-P).
(This procedure is, of course, only acceptable in a sample.)
If you have not activated the PROGDB.SWITCH switch before a CPU STOP, the
parameters of the cam in the parameter DB are not set back to the original values.
You must then download the parameter DB to the CPU again.
Error Evaluation:
If an error occurs in execution, the step sequence is stopped and simulation
deactivated. The value -1 is entered as the step number.
Try to create cam errors that are entered in the PROGDB.CAM_ERR bit as group
errors by the central error evaluation.
•
Set cam positions in VAT1 that are higher than the end of the rotary axis.
•
Enter negative cam positions in VAT1.
