I have GSM1 (OS/2) machine and it does not zero. The Y axis comes to all the way front to hard stop. I replaced the limit switch before the hard stop and can not find any way to test the signal from limit switch in diagnostic. I like to replace the c

On the HP Servo panel there are LED's that indicate state of limit switches - so you can see if the problem is in the switch or somewhere else. Did you check it?

Hi Marco, most likely your axis has two limit switches and possibly a home sensor. Limit switches are NC and in case of bad connection or wire break the axis will not move, no matter how many cards you swap.

Tom, Its not the scale but the switch itself because while zeroing, if you activate front limit switch for Y axis, Beam should travel back to look for home pulse. It looks like switch signal does not reach to the system.It is really hard to trace the

Check out all of the 941 sensors in the loop. Sounds like you have a limit switch problem. Rick

Are the arms pulling the cart all the way in? Possible part blocking the limit switch. does the cord have power? If I remember correctly, we once had to adjust the mechanical stops on one of ours so it would make the switch.

Try cleaning the linear encoder reader. I've had dust build up on two of my machines resulting in failure to calibrate. Blowing out the reader heads with gentle compressed air resolved it.
