Relay 17 backwards?
Fault output relay 17 has continuity between COM and NC terminal with no power applied to MPU11 and GPIO4D boards. My GPIO4D board is labeled different than what your 2010-08-17 install manual shows. My E-stop circuit works fine between Mach 3 and GPIO4D board, output 1 engages and disengages as described. Relay 17 as etched on my GPIO4D is NC-NO-COM. Is this a problem? With my relay wired as per manual, I have continuity between NO and COM terminals. The E-Stop circuit operation does not affect relay 17 outputs. Any answers? Thank you, Metalstech . MPU11, 9/25/09 101509 0082. GPIO4D, 7/16/09 version 0003. Mach3 version 3.043.022 Ajax Plugin version 1.16 Copley Junus drives.

Re: Relay 17 backwards?
That sounds like expected behavior for a normally closed circuit.Metalstech wrote:Fault output relay 17 has continuity between COM and NC terminal with no power applied to MPU11 and GPIO4D boards.
Do you mean a software estop in Mach is not affecting relay 17? or your physical estop switch is not affecting relay 17?Metalstech wrote:The E-Stop circuit operation does not affect relay 17 outputs.
I do not believe the physical estop should affect relay 17. From what I recall that relay only tripped when I would hit reset from inside Mach.
Output 1 only should trip on a PLC event like loss of communication with the MPU11.
I had what sounded like similar problems upon first reading your post. In my case it was ultimately resolved with the inclusion of a Mach Brain in a later plugin release. A brain needed to operate "Fault Out" Output 1 which was not occurring before with Mach when wired according to the instructions. http://www.ajaxcnc.com/ajaxbb/viewtopic ... +out#p1827
