- NC Start disable in this channel.
- Alarm display.
STOP F is enabled, that means a message is generated and NC start interlock is set (if
only data cross-comparison is activated), or, with active monitoring, the immediate
switchover to STOP B. Display on the NC/PLC interface occurs.
Find the difference between the monitoring channels. The error code indicates the cause.
A possible cause is that the safety-related machine data are no longer identical or that the
SGEs do not have the same level (recalibrate). If no error of this type is apparent, an error
may have occurred in the CPU, e.g. a "flipped" memory cell. This error can be temporary
(in this case it can be eliminated by a Power On) or permanent (if it occurs again after
Power On replace the hardware).
If safe monitoring was active, STOP B was also enabled automatically. It is necessary to
switch the control off/on (POWER ON).
Error codes for STOP F for 840D/611D:
0: No error. Definition: There is no error in this channel. An error may have occurred in the
other channel. Cause, remedy: Search the cause in the other channel and interprete the
error code.
1: Results list. Unequal control of the functions via the SGEs. Evaluate precise error cod-
ing in the 611D-MD 1391 and 1392.
2: Results list. Check cam tolerance, evaluate precise error coding in the 611D-MD 1393
and 1394.
3: Actual position. Incorrect encoder evaluation (check MDs). Differently stored standstill
position.
4: No cross-comparison.
5: Function enables. Enter equal MDs.
6: Limit value for SG1. Enter equal MDs.
7: Limit value for SG2. Enter equal MDs.
8: Limit value for SG3. Enter equal MDs.
9: Limit value for SG4. Enter equal MDs.
10: Standstill tolerance. Enter equal MDs.
11: Upper limit value SE1. Enter equal MDs.
12: Lower limit value SE1. Enter equal MDs.
13: Upper limit value SE2. Enter equal MDs.
14: Lower limit value SE2. Enter equal MDs.
15: Safe cam 1+ (+tolerance). Enter equal MDs.
16: Safe cam 1+. Enter equal MDs.
17: Safe cam 1- (+tolerance). Enter equal MDs.
18: Safe cam 1-. Enter equal MDs.
19: Safe cam 2+ (+tolerance). Enter equal MDs.
20: Safe cam 2+. Enter equal MDs.
21: Safe cam 2- (+tolerance). Enter equal MDs.
22: Safe cam 2-. Enter equal MDs.
23: Safe cam 3+ (+tolerance). Enter equal MDs.
24: Safe cam 3+. Enter equal MDs.
25: Safe cam 3- (+tolerance). Enter equal MDs.
26: Safe cam 3-. Enter equal MDs.
27: Safe cam 4+ (+tolerance). Enter equal MDs.
28: Safe cam 4+. Enter equal MDs.
29: Safe cam 4- (+tolerance). Enter equal MDs.
30: Safe cam 4-. Enter equal MDs.
31: Position tolerance. Enter equal MDs.
32: Reference position tolerance. Enter equal MDs.
