Hi. The Mach3 output, which activates a fixture clamp, deactivates with E-stop. I want the workpiece to stay clamped after E-stop. I also need to activate and deactivate clamp with a Macro during operation. Thanks Edward

Can you fit a double acting valve so the fixture needs to get a clamp and unclamp signal ? Once clamped the valve spool will stay in the clamped state until the next unclamp signal, after e-stop is reset. You will need two spare M codes to operate these outputs from within a macro. The spare M codes are PLC outputs. You may need to buy the extra M codes including output driven relays and wiring from the OEM.

Do you have it wired in the Estop circuit, check how it has been wired??

On paper, it appears I can use a mechanical relays normally closed contacts and let the contact spring act as default on/clamped. The SSR could just drive the relay coil. One less output pin. You may also may be able to open rather than close a SSR with an output pin but I don't know how to do this? Thanks all, Edward
