Breakaway head sensor?

[Jeremy Schiffer]

On occasion, on our CS41, when taking it out of e-stop, it will go right back into e-stop. The PLC screen says "check sensitivity of breakaway head sensor". This is not mentioned in the manual, or anywhere else I can find. So, what is it, where is it, and what's the procedure to check/adjust it?

Sometimes the plug on the front of the motor can get loose and cause it to do that. There is a little screw that holds it in place but doesn't necessarily keep it tight or from getting dust in it too.

Hi Jeremy, It is probably the contacts on the estop button. It is probably losing 24V when trying to enable. I would replace the normally closed contact on there. It is the Contact that has the blue wires. Our part # is LB00757. Mfg#IDEC HW-C01 CONTACT BLOCK 1NC RED (CE). Thanks!

The e-stop button was my first suspicion. If it had a wonky connection, I'd expect that engaging and disengaging it would normally (temporarily) fix it, but it never seems to.

Forrest, I'm not sure what plug you're referring to, I don't see one with a screw on it.

I think he is referring to the main wiring connector on the front of the router spindle. There is a small screw that holds the plug in there. The Estop contacts can be very intermittent
