meindert.norg Posted January 22, 2011 Share Posted January 22, 2011 LS, I have a Turbo PMAC2 system with an ACC 24E2A (2 axes expansion board). I have 2 motors connected to this ACC 24E2A. When I want to know the actual motor 2 position, I check M626 which is linked to [b]Servo IC 0[/b] channel 2: see the suggested M-variables: [quote]; Servo IC 0] Registers for PMAC2 Channel 2 (usually for Motor #2) ; Motor #2 Status Bits M262->D:$00010B ; #2 Actual position (1/[Ixx08*32] cts)[/quote] However, when I connect a user-bit to the front-panel flag connectors on the 24E2A (USER2), I need to read M1015, which is the USER2 flag input of [b]servo IC 2[/b], channel 2 (the suggested M-variables list indeed suggests that this is the First Acc-24 channel 2). [quote]; Servo IC 2 Registers for First Acc-24 Channel 2 (usually for Motor #10) M1015->X:$078208,19 ; USER2 flag input status [/quote] Why is the #2 Actual position information available on [b]IC-0[/b], ch2, and the flag information on [b]IC-2[/b], ch2?

Richard Naddaf Posted January 24, 2011 Share Posted January 24, 2011 with UMAC systems, Servo IC numbering starts at #2. The Turbo SRM states three sets of suggested M-Variables: - Turbo PMAC1 - Turbo PMAC2 - UMAC If you download the suggested M-variables from the Pewin32Pro2 under Configure>M-Variables, it will automatically download the correct set of variables.

meindert.norg Posted January 24, 2011 Author Share Posted January 24, 2011 Richard, Thank you! I knew about the Servo-IC #2, but totally missed the UMAC suggested list in the Turbo SRM. I was working with the Turbo PMAC2 list. Regards, Meindert Link to comment Share on other sites More sharing options...
