Servo Amp CX5X CX5Y jumper blocks

[Bruce Griffing]

On my Kitamura Mycenter 1 0MC system, I have a A06B-6079-H106 servo amp on the Z axis. I recently bought a take out servo amp on ebay of the same number. I was getting ready to put it in my machine to test it and I noticed that the two amp are different a subtle way. My amp has two jumper blocks on the front marked CX5X and CX5Y. In my machine, the CX5Y block has a jumper mounted on it. On the take out amp, there is a CX5X jumper block, but only a space on the PCB for the CX5Y jumper block - no jumper block. It was clearly this way from the factory - not a case of the item being removed. If I had an extra block I could install it - OR I could remove the CX5X block and put it in the CX5Y position. This leads to my question. What are these jumper blocks and what do they do? Second - What should I do with my new (used) amp?

The two connectors are to do with the battery for a Absolute position encoder

the CX5X is the 6V battery connector the CX5Y is a link to connect another servo amp to that battery.

I expect you previously had an early model.

normally the jumper is found across the CX5X on non ABS pulse coder (battery) machines

None of my servo amps contain batteries, but the system has 3 1.5V D cells. I understand that they are for the parameter memory. I don't think I have any absolute coders, but I am not sure what Kitamura used in this machine. It is a Mycenter 1 built in '97.

I did notice another difference between the two amplifiers. The amp that came with my machine has a capital letter G in the upper right hand corner of the paper label that contains the part number, etc. My new (used) amp has the letter D in the same place. I assume this means that my "new" amplifier is actually older than the one in the machine.

I soldered a 90 degree two pin header into the empty CX5Y spot and added a jumper on the "new" amplifier. I assume it won't hurt anything. Tomorrow, I plan to try the new amplifier in that configuration, unless someone suggests otherwise.

Well, my new (old) amp works fine. Thanks to MM, I had little hesitation in trying it. My mods to add the jumper were unnecessary, I'm sure, but they were done before I knew what the jumpers did. There have been some pretty cheap Fanuc servo amp take outs on ebay lately - so keep you eyes open. Mine turned out well.

Yeah, Bruce I've gotten lost of cheap FANUC stuff off eBay. (see my FANUC build posts)

My particular servo amps are the A06B-6058/A06B-6059 type which are for the "S" servos and spindle servo. However only one of them came with a top board. They were on ebay for less than $100.00 US.

I am still wondering if I could use them with the 15M, 0M or 11M.

A side note: These GE FANUC Application pages helped me a lot finding the right part numbers.

http://application.gefanuc.com/servi...rts/0c0001.htm FANUC 0C
http://application.gefanuc.com/servi...ts/11a0001.htm FANUC 11 A
http://application.gefanuc.com/servi...ts/15a0001.htm FANUC 15 A

They also have the 15 B, 16/18 A, 21 B, and maybe a few others (I didn't look). I also did not play with the rest of the application.gefanuc.com site to see what other pages it may hold.

Just replace the "xxx" in the "/xxx0001.htm" of the URL with your model.
