I am using RSLogix 5000 with a Kinetix 6000 servo system and I sometime see the value of the Master Encoder change after a very simple program offline edit and download. (Like changing a NO contact to NC contact)
Hardware
Master encoder - Sick SRM25-7-H10S-GA or SRM50-BC02-M02-S
(HIPERFACE MULTI-TURN ABSOLUTE) Connected in the AUX FEEDBACK connection.
Servo Drive - Kinetic 6000 IAM 2094-BC02-M02 (there are 2-12 servo drive is the systems)
I stop the machine on Master Position 0.000.
I edit the NC contact to NO offline, download and the Master Position sometimes changes to something else.
I made sure that my offline program and online program are the same before the edit. The machine is ESTOPed and does not move between the edit and download.
If I do this 10 times as a test, I see the master position change 2 out of 10 times but not with any consistency.
All motors and the master have been homed properly.
No other issues seem to appear after the edit and download.
I have seen this occur on RSL5000 ver 16, 17, 19 and 20
If you have seen this problem and know how to prevent or fix the problem I would appreciate and assistance you can provide.
As of now I just write down the master position before the edit, edit and download, then I go back and Home the master at the position I wrote down.
