I have been testing a XMD with a XM21 on sercos. looked like there is communication issue between XM21 and XMD on sercos. Indraworks used was V15 and CtrlX drive engineering was V118.1. no matter I powered up the drive first or XM first. the XM always stayed at P2. the power control of the drive was setup as below and wired BB to XG31.3 and use XG31.8 to turn on the power for second axis.
the only way to turn on drive to AB was to manually switch the sercos to BB without a program. there was no error showed.
is that normal or did I miss any setting caused this issue?
your help is appreciated.
If you switch manualy your XM in P4 does the Drive follows ? It might be your target start-up phase in your XM.
Thank you YUL725 for point it out. I could get the drive into AB after manually switched the XM to BB and run some plc open commands. normally C450 is set as 4(BB) and I didn't check it and it was set 2(P2). however after I set it to BB. the sercos is getting into BB and shows no error, but the drives are still in CM mode and don't automatically get into BB. now I need to manually switch the phase from drive side. I cycle the power few time times and nothing changed. the drives are configure to run into run mode automatically after sercos in BB. see some screen shots below. there is another issue I want to mention here. if the parameters are changed in drive from CtrlX drive engineering it won't automatically update the same parameters in the controller or vice versa. have to make sure the parameters the same at both sides. I don't know if there is a plan to make the parameters updated at same time on both sides automatically.
It looks that your firwmare is not up to date it migth be the issue, 03V14 is the current version. Just to make sure , you are running this on an MLC15 system ?
Thanks, I will update it and try it again.
Hello YUL725, I did get the firmware of drive updated to 03V14 and Indraworks has been 15V16. XM got BB however the drives in CM. it is the same as before. the XM showed drive in PM, but actually the drive was in AB. was there other things I missed?
Did you leave the Drive in PM on the motion node ? (rigth mouse button Menu item "Parametrization Mode Active"
I could manually active the drives into parameter mode or even operating mode. however after having the power cycled the XM was in operation mode, but the drive s was back to CM mode and the XM showed the drives in PM mode. there was no checking for mode changes in communication on sercos between the two. I found out that Matser communication-sub-device coupling active was not lighted up, which meaned the drive was coupled with the control. actually they was decoupled.
