11. Wiring Limit, Estop and Fault Inputs
1. Limit switch, Estop, Spindle Fault & Lube Fault PLC input wiring
All inputs used
for Limit switches, Estop, Spindle Fault & Lube Fault must be wired in Normally closed
configuration. The switch should be closed when the machine is in it's operational state.
Wiring any of these inputs in a Normally Open configuration is dangerous as there is no
way to stop the machine in the event that a wire breaking. It also prevents noise from
causing spurious faults because the signal is being electrically held at the operational
level.
The I/O configuration on every machine is different. While the examples below assume
dry contact type switches and utilize 12VDC, your machine may utilize different voltage
levels and different type devices devices such npn, or pnp proximity sensors. If your
devices are proximity sensors, they MUST be 3-wire sensors, 2-wire sensors will not
work reliably. Make sure the SIPS you installed in section 8 match the voltage levels for
your devices as voltage levels.
Failure to install the proper SIPS to match the voltage levels being used will damage the
GPIO4D
Connect your limit switches, lube fault spindle fault & Estop as shown:
Spindle Fault -NC Relay in VFD or OL Spin contacter
Lube Fault -NC Switch on Lube Pump
