I'm converting a Clausing 5900 series manual lathe to CNC:
https://picasaweb.google.com/marty.escarcega/ClausingCNCLatheConversionMaking good progress, servo motor mounts/ball screw supports almost done.
Been working on the control and I have some questions:
I am using a Galil 1740, computer and plug in ready to go. I have uploaded my ICM1900 pin chart. I'd like someone to review it and see if it looks ok. X/Z axis typical. Want to use Y to command the VFD +/- 10VDC, W is for a future lathe turret.
My questions:
1. Kenny mentioned something about changing a chip on my ICM1900. Which one and when would I need to do that?
2. I would like an output for a mist system. It will simply turn on and off a relay. Which pin(s) can I use for such outputs and are they typically +5VDC to control small control relays?
3. I need an ESTOP input. Which inputs are typically used and do I use a ground input or a +5VDC input? or +12VDC input
4. I need an output (Like a charge pump). Once the computer is on line, I planned on turning on a +5VDC control relay which would in turn give me control voltage through one of the contacts, I press a system reset button and it will pull in a contactor to energize the Servo power supply and enable the VFD (Should I use a contactor for line voltage or just use low voltage enable circuits)
5. I planned on using limit switches on both ends of travel, one of which I had hoped to double as my home switch. I assume this is possible?
6. There are Auxillary Encoder inputs on the ICM1900. I wanted to use the X/Z auxillary inputs for an 100ppr encoder on each axis. From what I gather, I need to put an IDC 25 pin connector on the Galil motion control board and use a DB25 straight through cable to the ICM1900?
Anything else I should consider?
Thanks in advance,
Marty
