Rockwell Kinetix 350: AxisHomedStatus signal is reset on powerup

[kelad]

Hello Everyone
hardware: 1769-L36ERMS Compact GuardLogic 5370 Safety Controller, revision 30.014
drive: 2097-V32PRO-LM Kinetix 350, 2A, 240V, Integral Filter Ethernet Drive
motor: TLY-A130P-Bxx4
Our motor has an absolute encoder. We have written a special program which will run and set the MAH command. This works fine. I want to capture the scenario where the ".AxisHomedStatus" bit goes false because of a hardware problem etc. I will then bring alarm and the engineer must then re-run the special program. The problem is that on bootup, this bit goes false for short period. I know I can put a on-boot timer to delay the looking at this bit, however I was wondering if there is a drive bit which I could use instead, like "driveBooted" or something else.
Thanks alot

I think you have the question and solution in your own post. Keep it simple.

Maybe as you say...it might be worth monitoring the "entrystatus" so you know the drive is back online- then give a slight delay before reading in the tags.

Otherwise have a look through your CIP_DRIVE UDT and see if there is any other tags of use.
