AXBB charge pump fault

[northbynate]

Thanks!! This is fairly similar to my original plan (minus the relay). I just got hung up on the wireless mpg part and the two types of estop (hard and soft). From what I understand the charge pump can be set to stop when UCCNC is on 'Reset' mode. In Jazz's case this would then be passed on to the safety relay which would in turn cut the contactor. In that case an estop from a wireless mpg could act like a hard wired estop - albiet passing through a layer of software first. Getting the contactor back on would then require both clearing 'Reset' mode in UCCNC and using the physical button to latch the coil of the contactor. I guess my question would be is it possible to have that same behavior from a wireless estop as it is from a hard wired one?

Don't think it works as you think, there is no setting in the software other than to keep the charge pump loaded at all times.

This is from the manual

"If the 'charge pump always on" checkbox is not set then the PWM signal is only active if the software is not in reset and inactive if in reset.

The charge pump signal can be used to enable an external electronics only if the UCCNC software is loaded or if it is not in reset making the operation of the electronics safe."
