Limit switch
--------------------------------------------------------------------------------
I have a limit switch that persistently trips during a program and requires me to stop the program, re-reference etc. I need some help in trouble shooting this thing. Following info might help:
Mach for the controller
Micro switches for the limits and home combined. A total of three dual purpose switches.
Mach does not indicate which switch is tripping.
Switch wires are shielded and grounded with the only bare area just before the screw terminals.
X and Y switchs are mounted upside down with the plunger hanging down.
Z switch is mounted with the plunger horziontal.
Wired for nc.
Due to Mach allowing it, Z and Y are using the same pins but when referencing the axis reference at different times.
Limit are set so any switch will Estop the machine.
Any help would be appreciated. I am at a loss and this is costing me precious time.
Mike
Switch is a Omron with a .016 pre-travel
General Purpose Snap Action Switch, Actuator Roller Plunger, Panel Mount, Maximum Operating Force 8.8 to 12.3 Ounces, Maximum Pre Travel 0.016 Inch
