Need Help!- Choosing a FANUC Servo

[gbowne1]

As many of you know I have several FANUC control builds to complete % complete with the exception of the 15MA.

But, I still have to pick out at least 30 servos servos from the masses of the many different FANUC servos for my builds, with the exception of the servos for my 15MA machine which is a 3 axes milling machine.

This is probably the weakest point in all my knowledge.

Anyone have any suggestions to start with as how to choose a servo?

I'm personally leaning more towards one of the following types

A06B-0128 type 6/3000
A06B-0315 type 10S
A06B-0501 type 10
A06B-0314 type 5S
A06B-0502 type 20S

although I'm looking at others too, I will follow up with that list soon.

I do have many of the different A06B-6058 and 6059 amplifiers and their top boards. I also have the amplifiers A06B-6079-H101, H103 and H106. Do these need their own power supply like one of the 6077's?

The 16MB and 18iMA need servo amps too. The 6MB2 and 10TF I have VCU's for them, but haven't picked the servo.

Here's the configuration on my 16MB. In most cases I have both boards.

the 20S was the only motor that will run on both 185 and 220 volt amps- watch the bxxx number though- they could be had with taper shaft mounted black encoders or the red 4 bolt/oldham coupled encoders. red ones can be incremental/absolute/serial, in the black ones, most will be incremental. if the last part of the number is a B2xx, it has a brake, B0xx no brake.
xx=01,02,03 black style 2000/2500/3000 ppr incrementals
xx=04,05,06 red style 2000/2500/3000 ppr incrementals

(above is from memory- might be wrong... theres a lot of other numbers for serials, dont have any info handy)

if you run a 20S you could use analog 6050s for your 6/maybe for the 10 if its analog axis, and use same motor with 6057/6058/6066 maybe even other drives on the newer PWM output controls- but you will likely need Alpha encoders


on the digitals, personally Id opt for 6057 amps(metal chassis) but the 58s were ok too. 6066 and early alphas(6069?) with built in supplies were not as reliable from what Ive seen and the honda PCR connectors totally suck to solder.

note the 6050 and 6057 will require a transformer for the oddball 185 volt input, but if youve got that many motors, imagine youre sitting on a few servo transformers too...

thinking about servos a bit deeper...noticed yesterday on a few big 420F/420A robots they pulled out of storage, the upper 3 axes all use 10 servos(0501) and A controllers had metal framed 6057 (185v)amps, F controls run 6058 plastic(220) amps- I need to check out the servo parameters and see how they got the 185 motor to run on high voltage drive- weve still got hundreds of 501 size 10 motors stored away, but are running low on the 20S for red encoders...the bulk of the 10 motors use red encoders.
probably wont find a 'motor type' to set default parameters, but if GMF did it, there has to be a way to hand type their parameters into a cnc- this might give us a lot more useable servos for our low voltage 6057 machines

Yeah I really have to find the right servos. I was told servos that are equal to the FANUC 0M servo are good enough for most milling applications. I know that any of the servos with numbers A06B-06xx-Bxxx are DC servos. I have incoming 220v-240v 3ph power.

My Builds:
6MB2 (control is finished! I/O is about 1/2 complete)
10TF (control is finished! I/O is not finished)
16MB (control is finished! I/O is not finished)
0TC (still in storage)
0MC (still in storage)
18iMA (work in progress)
15MA (control and i/o are finished!!)
11M (haven't worked out which particular model this one is did a build log on this one a while back on here)

Here are the servo amplfiers I am looking at:
A06B-6079 Alpha w/6077 Alpha PS
A06B-6047
A06B-6050
A06B-6058 S Series w/6059 spindle amp.
A06B-6066 C Series
A06B-6089 b Series

I would prefer a compact installation but the NEMA floor cabinets I order usually have quite a bit of room and are very much similar to the cabinets FANUC supply especially with the tape reader door.

I do have a crate of FANUC transformers that have to be gone trough. Most of them are the FANUC A81L-0001 and A80L-0001 types. The biggest being about 8.5-9kVA. They are the mostly the A80L-0001-017x and A80L-0001-034x types. Also have some of the A81L-0001-xxxx line reactors. Any ideas on what to choose here?

The 18i is a Work-In-Progress.

The shop is getting full.. 6 CNC milling machines and 2 CNC lathes. The first of the two lathes just got here in August. Yay!!

I may even look at adding a FANUC bot for a workpiece loader so that I have a tireless employee lol. Wouldn't know what to go with on this. I did manage to locate one of the I/O A03B-0801-C462 Robot control modules

I believe you are rapidly becoming some kind of Fanuc Masochist .

Well, yeah, I don't think I will ever have the chance to have every FANUC control ever made. I just don't have the room.

I'm looking forwards to the 18iMA build getting up and running, as I am with the others.

Oh yeah, my 10TF is just like the one on this lathe. And the lathe is actually very similar although the tool changer is a bit different. I like the color CRT.

I just hope to find the right servo and amplifier combinations.

the screen layout on that control looks virtually identical to the Fanuc 15TF Mori SL35 I used to run. 14" color is very nice especially with FAPT compared to the old 9" green screens of the past
if you're building it yourself you would probably only need to change the graphics PCB and screen to get the same functionality.

[gbowne1]

Yeah.. My 10TF control is actually a lot like blakemachine's 10TF/TEF on his hitachi seiki HT20 lathe post here. Mine has essentially all the same identical parts, even the transformer I picked looks the same (at the bottom of photo #5). I do like the color with FAPT. I do have the A20B-1000-0850/-0852 MDI graphics board.

My 15MA has the 14" color CRT.. not the monochrome 14".

I had problems with the FUJI magnetic contactor type SC (also type SRC or SRCA) when I first started the 15MA. Gonna have to find one for the 16MB. I misplaced my wiring diagram for the contactor. Anyone got one?

Back to servos..
