Error Evaluation:
Create a data error by setting the reference point coordinate “CHAN_1”.REFPT in
VAT_CTRL_1 outside the working range or the end of the rotary axis. Then
activate the “set reference point” job with “CHAN_1”.REFPT_EN=1. The CPU
changes to STOP. (In a sample, this is the simplest method of indicating an error.
You can, of course, program a different error evaluation.)
Open HW Config and double-click on the FM 351 or FM 451. The parameter
assignment software is started. Display the cause of the error in the dialog by
selecting Test > Error Evaluation.
The status values in VAT_CTRL_1 still indicate the status before the CPU changed
to STOP. Update the status values to view the error and done bits of the jobs.
To eliminate the error, follow the steps outlined below:
1. Enter a permitted value in the control value.
2. Switch the CPU to STOP.
3. Switch the CPU to RUN-P.
4. Activate the control values. If you activate the control values before the CPU
restarts, they are reset by the initialization in OB100 and therefore have no
effect.
