Which products are affected?
Position controller 9300EP <= V8.0
What happens?
In case of manual jog with intermediate stop (C1260 = 1), the drive shortly stops at the parameterised intermediate stop positions C1261/x and immediately afterwards starts traversing again.
When does the problem occur?
If the acceptance of new travel profile parameters during the running positioning process is activated (POS-PARAM-RD = 1) simultaneously with manual jog with intermediate stop (C1260 = 1).
New travel profile parameters are accepted when a LOW-HIGH edge occurs at POS-PARAM-RD. At constant HIGH level, new travel profile parameters are accepted every 10 ms.
Possible diagnostics?
Check whether POS-PARAM-RD = 1 is set during manual jog with intermediate stop (C1260 = 1).
Short-term measures/recommendations?
Switch input POS-PARAM-RD = 0 during manual jog (POS-MANUAL = 1).
Evaluation:
By resetting the positive and negative control signals for manual jog, the drive can any time be stopped by the operator (POS-MANU-POS = 0 and POS-MANU-NEG = 0).
The set position limits (C1223, C1224) and the travel range limit switches are always operative in parallel so that the permissible travel range will always be monitored.
