Denford Triac VMC with ATC Conversion / Fix

[Chaz]

Either way can be used, 4 and 5 or 5 and 7 depends on the application. When the tacho option is used 6 and 7 are used for this and 4 and 5 are used for the spindle run, if yours is wired that way use 4 and 5. The guard relay will be in the circuit to limit the operation of the spindle if the cover is up, but the sgr would still be the relay that connects 4 and 5 on the sprint board.

PS. sfr may have replaced sgr.....edit...... Looking at the other photos sfr has replaced sgr, and common practice with denford machines is to control the relay on the ground side. To the left of the sfr is the srr, this reverses the spindle by changing the polarity to the motor.

Thanks.

A bit stuck at the moment. Have wired in the Y encoder but a bit of confusion about whats needed next. I know I need 0V and 10V Ref but a bit confusing as I also have an enable option. Going to power up now and see if I can get something moving, still need to config the CS Labs and install Mach, so still a bit to go yet I think before I can get anything moving.

I managed to get 110V, need to see whats holding out the main contactor now, must be an E stop or similar.
