Yes it is a f1. If you had a shielded wire coming from the second 502 D/A board your speed was probable handled completely in the CNC.

Do your tools have a retension knob or threaded for a draw bar?

Retention knob.

That PDF that I posted for the PLC is a programming manual, no wiring details.  ........Rats.

The OUT. SVO-ON supplies ground directly to the relay of which the other side is connected to +24v (no PLC invovled.).

Where does the 24v come from.  The only 24v I see is from the power supply I took from the card cage.  24v on that isn't connected to anything yet.

There is a 24V power supply right above your PCB 801 board ( The one with 3 icecube relays.)

My tools are threaded for a draw bar with a Kurt actuator ( 3/8" CP air hammer.).

That's what I get for posting info from what we laughingly call my memory.  The machine is only 50 ft. from the office.  Too lazy to go look.

So now I'm ready to whack a ribbon cable and connect an enable (1) from a pixie.  From the drawing, the odd numbers on the connector are on one row and the even on the other?

Here is the diagram for mine. I would imagine the CNC to PLC interface would be the same for both machines.

The rest of the diagram will be like using a map of Alabama get around in Georgia!

How disturbing it is to me to have to display the level of my ignorance.   That sheet IS in my wiring diagrams.

Sending you a PM

Ashby

Actually that is a good thing!

As far as ignorance, I would not be much help if you had a machining question.

Now I'm trying to figure out my limit switches.  I have 3 per axis, all Normally Closed . On the X........ X+ & X-(24V), overtravel (servo disconnect)  My Accu-Step BO board has one lug for each axis,  Labeled "LS".  I have read the section in the Mach 3 users guide on limit switches and the documentation that comes with the BO board.  Can't see that I can use 3 per axis with what I have.  Still have to turn on coolant after I (we) get this down.

I have another printer port.  If I need another BO board I'd appreciate a recomedaton or two.  Doesn't seem that I would need anything as fancy as what I have.

Ashby

EDIT:  Could I use the XYZ minus switches as Home?
         Not disconnect, run a jumper from NC contact on switch to LS lug on BO board?
         Don't forget >>> I'm easily confused.

P.S.  Merry Christmas
       Happy New Year
       Have a nice Easter.!!

I tried NC contact to BO board as above.  No joy.
The BO board wants to see a connection to ground broken by the limit sw.  The 24v negative from the power supply isn't connected to chassis ground.

So if I connect limit sw NC to BO board AND power supply 24v negative will that work ??

Or will that mess up PC board 803 ?

Ashby

This is how mine are setup. If yours are the same, I would leave the middle switches as is ( This is the loop that kills the servos.).

The RED (X+), GRAY (X-), ORN (Y+) and YEL (Y-) will be the inputs to the board. The BRN wire that supplies +24v to the switches will have to be switched to ground now.
