    If it's moving on it's own without being commanded then Reverse the Encoder direction in the CSlabs plug-in.

    with the cover, unscrew the tab that locks into the guard solenoid from the cover and leave it in the guard solenoid.

    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, so solved the 140 feed to the DER. It comes from the X axis wiring and is not part of the Y or Z. To enable, this pin needs to be taken to 0V..

    Can I double check something, for the 0-10V Analog input, this shows using 1 and 14 for the first axis. On the pic below, the left hand side is the wiring of the drivers.

    Is VRef- 0Volt or something else?
    I assume VRef+ is the 'up to 10V'?

    Are my red lines below correct to show how they should join?

    Ok well kind of right but your needing ANALOG +/-10V OUTPUTS for the Channel(axis) your using.! . . . It's not 0-10V ANALOG INPUTS they are very different things.!!

    I realise you probably know this but it's these little details and wrong INFO back to us here that can get confusing and you in BIG trouble if we do and your letting out Magic smoke.!

    Vref - = Negative Voltage ie: -5v = right direction at half Motor rpm
    Vref + = Positive Voltage ie: +5v = Left direction at half Motor Rpm

    Manual will show you which pins are for Negatve and Positive for Each Channel(axis). Careful you don't Mixup the GND because the Channel GND's are different to Analog input GND's on same connector.!

    OK, have some success. Long story ...... dont trust things till you have opened the connector and verified each pin.

    Argh the old pin shuffle gotcha trick.!! . . . Got me too many times. My prefered way of converting is to rip the guts out and start again. It's often quicker than chasing dodgy wiring and connectors.!
