That wiring diagram will make it a lot easier. I have no wiring diagrams for the machine at all and some of the (written in) labels are faded as well. Thanks.

Thanks, I will attempt making one of these and test the system the way it is. I'll measure the slots to get the spacing right. I thought it would be something like this or switches, but could never see one. Could you say where this was mounted over the slotted disk? If facing the machine is 12:00, was it at 3:00 or 6:00? Also, do you remember the m command in the dynapath for the toolchange in case it is different than the manual (I have the dynapath manual)? Since this toolchanger wasnt used by the last owner, he didnt have other information. Thanks

I was going to leave the encoders. What are the advantages of changing the encoders? Is it index homing? Which encoders did you settle on?

The omron plc uses parallel bus to communicate with the controller (i can see that would be complicated). What does the siemans use that is easier? is it serial modbus? or is it directly from the galil board? I dont know this stuff very well. Maybe you could share this if you get it working. Need any granite countertops?

I found some pictures of similar machines last night without toolchangers. One has a picture of the original Kasahara logo which probably is difficult to find. The oter is a Vulcan. These come up so rarely so  I attached pictures.

Wow, glad to see there is another one of these. I do have another cabinet with the extra io too. Could you send me a picture of the photo diode part and where it is supposed to be located. Did you download your ladder logic and do you have a copy of it? I guess the only way to get it off the omron plc is with a pro16 programmer. Is that what you have? How far along are you in the retrofit? Did you continue using the servodynamic drives? The servos? Anyways thanks for the response. Hope to hear more.

Galil / Re: galil combination for tool changer, mpg
« on: March 16, 2011, 05:14:12 PM »
whats the difference between pulse width modulation (PWM) inverters and AC inverter that I have with the ARNI board and VFD (variable frequency drive). PWM uses an axis in the galil but VFD does not? Would i have to replace my drive with vfd drive? or am i really confused?

Galil / galil combination for tool changer, mpg
« on: March 16, 2011, 02:37:55 PM »
The information on my machine is in Show nTell in this thread: http://www.machsupport.com/forum/index.php/topic,17828.0.html

1. I wanted to know what my options are if I want to use a galil 1740 for 4 axis and spindle control and toolchanger. Do I necessarily have to use the galil for spindle control or is there an addon or modbus for that?
2. I suppose I could use a modio for tool changer to talk to omron plc and do i need an addon modio for pendant/mpg?
3. Can you use any Modbus with the galil or do you have to use the galil Rio?

Thanks

Here is more information from about the same year using the same board.
I guess it is 0-10v inverter with forward/reverse and on/off.

I guess its an inverter control board. I will research that.

Cat40 tooling on 5hp AC spindle using  ARNI-889 Toshiba spindle drive 50-4000 rpm (info on board:http://www.redrive.net/product/ARNI-889/ARNI-889-Toshiba-PCB-board.html). The PLC is a SYSMAC S6 (MODEL# 3G2A3-MP523). I dont know if it is modbus (how can you tell? Did they have it in 1985?). Also, x axis is 28" y axis is 13" and z axis is 17". It has limit switches on the z but none on x or y axis (soft limits are used on the dynapath 10).
