Hi,
I am seeking some help on a rather old axis motion controller. The controller type is an AB IMC 400-232-R, Series J, 2 axis motion controller with a firmware revision 303003.5B. It has 2 RIO output cards attached using the outputs as directly wired inputs to a SLC 500 controller input card.
My problem is that the machine tries to reset the axes by homing both axes to their individual home sensors. It completes the movement as normal and then just sits at this point with a message on the HMI saying the axes reset is in progress. It seems as if the servo's and drives are all functional. There are no faults on drives or motion controller.
Looking in the PLC code this message is held on by an input which is fed from the RIO output card. I don't have the original GML file but I got online today and managed to upload the script file which makes little sense to me and I am struggling to get the information from the controller to see why it is not acknowledging that the axes have completed their reference. I can see data for each axis which indicates that neither axis is in fault and I see when the axis homing signal is on. When it reaches its home limit switch the homing then says locked so all seems to be registering. I can jog the axis from the GML software also. However I can't get the information I need which is the reference acknowledge which seems to be the command to turn off the output on the RIO. Is there anyway of figuring out what turns on and off the outputs on the RIO from monitoring the controller or the script file? I am suspect that the 400 controller is defective in some way but I don't have a spare at hand. Any help would be appreciated. Thanks.
