Denford Triac VMC with ATC Conversion / Fix

[JAZZCNC]

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.

Connect the enable on drive to an output on IP-A and set the Enable 1-6 Output in Mach3 to port10 pin(which ever used). You can connect all drives to same pin to save outputs if you like.!
This will enable the drives when Mach is Reset and disable when Mach isn't.

If you want an extra layer of safety then run this signal thru your E-stop relay. So Enable can only happen if E-stop not pressed. This way the Axis won't be enabled even of Mach is reset( Which it shouldn't if E-stop is done correctly)

So I need to simply bridge between terminal 14 and 15 of the IRTA Drive. What function do I use on the CS Labs unit? Analog Out? Does this push out a voltage or does it simply close a circuit and work as a softswitch?

If I look at the analog out options, I have Analog output 0 (0-10V on pin 7) and Analog output 1 (0-10V on pin 8). I would have thought I needed to use the digital outputs? Sorry, a little bit confused, just want to 'make' a connection between 2 points.

Actually, from the 15 pin breakout, i dont have a wire to allow a bridge. Something else is holding out the DER relay, need to find that.

This could be changed later but needs rewiring.

OK, DER Relay working, it was the door latch holding it out.

Drives enabled, no movement yet. Not sure how to configure anything related to steps or similar, do I need to with a servo?

Chaz to many over lapping questions it's going to get confusing and dangerous if not careful.!!

Regards the Outputs it's Digital output you need not analog.
Analog is only for controling devices that need 0-10V Also don't confuse the Motor Analog outputs which +/- 10V with 0-10V.!! . .. Very easy done.

Regards motor tuning and setup then yes you still need to set this up. You'll need to know the Encoder resolution, any gearing ratio and the Pitch of the ballscrews to workout the correct steps Per unit in Motor tuning.

Thanks, as suspected.

I think I have the encoder details from the manual for the drives but not the rest, will need to try and work it out somehow. Are these values entered into Mach 3 or the CS Labs unit?

Does anyone know where terminal 140 comes from that feeds the DER? 60, which is the other side of the coil (0V) is common.

It's entered into Mach3 Motor tuning in the Steps per setup. Your encoder probably be 1024ppr and quadrature so 1024x4,
So steps per Calc will be 4096 x (Any Ratio) / (Pitch) . . . . . .Ie 4096 x 2 (2:1 ratio) / 2.5mm pitch = 3276.8 Steps per Unit

Also you'll probably need tune the Position/ Vff PID settings in the Controller for best performance. Provided the Velocity PID settings are setup correctly in the Drives them selfs then the Cslabs Auto PID tuning will most likely take care of this for you. It's in the Plug-in Config.!!

ADVISE YOU RTFM BEFORE doing this.!!!

OK, Y moves when I push in the DER manually. Not sure why - I dont know if the machine is trying to home or something else. If I restart Mach 3, does it 'forget' what it was told before?

Glad ive got movement, not sure whats impacting DER relay yet. It was the door latch, thats sorted, something else is now holding it out. Looking to try and reverse the direction, where is the 'jog wheel' in Mach 3? Ive seen a pic of one, is it a plugin?

Thanks, had seen that on a forum but it did nothing :-(

Checking again. So much easier to understand with Step / Direction ....
