Re: Control Pendant/Panel layout for your comments

I'm with you. Currently my E-Stop button is a NC in series with the
latching contact on my enable relay. When pressed, the relay drops
out and cuts the power to the stepper drives, the mill's spindle
motor and invokes the spindle clamp and brake. In order to re-
start, the "Start" button must be pressed. Using the "Start" button
to kick in the enable relay means that transients and other stuff
will not affect anything when the PC starts up. It works as well as
other schemes (like the charge pump circuit), but only requires a
switch latched relay contact.

Regards,
Jeff
