DO you know which Fanuc AC motors can run with the VSDE.
I tried some Control Techniques which did not work even after I replaced the encoders.

Im running some 750W DC servo motors right now but they arnt very gutsy at 2Nm.

So I was hoping to goto the following as I have 2 available locally at a good price.
FANUC A06B-0522-B351 AC SERVO MOTOR +

3 PHASE
8 POLES
STALL TORQUE 22 Nm
STALL AMP 2.9 AMP
90 V
AMB TEMP 40 DEG C
EXCIT PERM MAG
INSULATION CLASS F
APPROX SHAFT DIA 1/2"

PULSE CODER :
A290-0521-V581 PULSE CODER ABS2000P

[evo4wrx]

These are the other two motor options....

FANUC A06B-0315-B08-7008 AC SERVO MOTOR
TORQUE (STALL) 12NM
AMP (STALL) 7.6 A
RPM 3000
PHASE 3
150 VOLTS


OR

FANUC A06B-0128-B675#7008 AC SERVO MOTOR, USED
OUTPUT 1.4 kW
114 V
7.5 AMP
200 HZ
3000 RPM
3 PHASE
200 V INVERTER
STALL TORQUE 6 Nm
STALL AMP 10

Looks like you have the absolute encoder there, most likely off of a robot.
Does the Granite use the encoder for commutation? As the Fanuc AC servo's use a proprietary 4 bit code for commutation.

If you can get the encoder pulses off the encoder the granite devices will run it I have one that had an absolute encoder an absolute encoder but I was not able to get the encoder wired so it would work. the vsde's sense the commutation requirements and will then run from the encoder count, I just replaced the encoder with a differential encoder, I made an adapter plate to fit the motor and a nylon adapter to fit the coupling on the motor. it seems to work just fine now.

[evo4wrx]

I had 2 control techniques that were resolver AC motors that I replaced with Renco encoders but the things just wouldnt run. So im a little gun shy now leaving the world of DC. The other option is i go to Faunc 10M yellow caps but all the motors around are just so old.

[evo4wrx]

Can anyone confirm if this motor will work?

Fanuc Model 10S
Type A06B-0315-B032
12 NM
3 Phase
7.6AMP
Excit Perm Mag
2000 RPM
150V
8 Poles
Pulse coder

Not so fussed about the encoder I can pull them off and replace them with my Renco encoders I have a heap spare.

[Montabelli]

I am running model 5s with some with pulse coder some with trd shaft encoders coupled to the back of a cap screw in the end of the tapered shaft that the pulse coder was bolted to. I milled a stand off that use the original mounting screws.

the specs on the model5's are 110v and 6.8 amp 5.9nm. essentially
the same motor except voltage and power so it should run the model you cited

the alpha series will work fine to but I had to change the encoder. it has a different mount system than the pulsecoders, ti has a single slot swash plate on the back of the motor . I just made a nylon part that mated with it and was able to use more of the original mounting hardware to set it up.

[Al_The_Man]

The B032 shows up as a 2500p Absolute encoder.
I have used a shoulder bolt with 5mm(?) thread and shoulder to suit the Renco encoder.

Thanks 10 S it is then.....that will bring the lathe upto some decent speeds and get rid of the gears finally.

[Al_The_Man]

They make nice spindle motors also.

[evo4wrx]

I think I overlooked one slight issue.

Whats the dimensions of the motor 5s and the 10 s...could anyone help me or point me int he direction for that one. Ive googled about every combination of words that might relate to it but it comes up with nadda.

thanks.

5S motor and flange 5" sq, length 12" (w/o brake) flange to encoder end.
Straight Shaft - 2".
Motor 14" OA.

The motor part will always work with VSD-E as long as it's permanent magnet motor (DC/BLDC or AC). All servo motors that I have came across have been permanent magnet type. Only totally incompatible type is induction motors (typically not used as servo due to poor dynamic performance).

So pay attention to encoder. It must output incremental quadrature encoder signals to work with VSD-E.

All Fanuc (any any other brand, too) servos will work with VSD drives if they have compatible encoder attached. Commutation tracks are not needed as VSD-E can commutate based on encoder only.

[Al_The_Man]

The motor part will always work with VSD-E as long as it's permanent magnet motor (DC/BLDC or AC).

The majority of Fanuc red cap AC motors are 8 pole P.M. motors, the 6 pole P.M. appear to be fitted to Fanuc Robots for some reason and all robot motors are fitted with absolute enc. as a rule.

I ended up with 4 x 5S 3000 RPM motors. Should do the trick...will get my lathe rapids upto about 25m / min which I will be standing in the car park to watch

Will post some pictures tomorrow of the lathe build...its been a monstor effort and Ive been through 2 chasis builds to end up back on an old 2.5m engine lathe. Typical. Dont re-event the wheel. Fail.

[jsheerin]

Might be too late to help, but from what I've seen generally the older Fanuc red cap series with part numbers A06B-0xxx-Bxxx series motors that end with 01,02,03,04,05,06,10 have incremental encoders. So for example, A06B-0315-B004 is a 10S motor with a 2000 pulse incremental encoder. I have some of these and have tested them with a scope and the output looks like an incremental encoder anyway. I eventually plan to use these with some VSD drives. The higher numbers are absolute or serial encoders.

Hi there Al
We spoke some time back regarding our large 5 Axis mill still having issues with the Granite devices Drives .Seems to take for ever to get granite devices to respond to issues

Are you avalible to help us with the last lot of Questions

We are almost at a point were we are going to throw out the Granite stuff and deal with more reputable companies

[Al_The_Man]

Are you avalible to help us with the last lot of Questions

If I can, I will.
You can either post here, PM me, or email direct.

Thanks Al
These are the issues as follows,
We still cant get the drive to enable correctly from the VSDEPI interface (attached is a typical .DRC config file )

Drive will not enable with this configuration ,Even though enable 1 is lit in Mach 3
With 1 only cmd connector plugged into VSDEPI but not connected from VSDEX, I would expect to get voltage bettween pins 13 and 16 (analog in 2).However there is no voltage present when enabled or disbled

No # 2 Home limits signals do not work with cmd plug connected at VSDEX but unplugged from VSDEPI pins 2,7 = 5 VDC
pins 7,11=5 VDC when faulted OVDC when not faulted
pins 7, 12 = OVDC when home switch ( encoder pins 4 &8 bridged )configuration to opto 1 =home limit " Then i red change of state on pins 7 ,11

So opto 1 works fine and opto 2 does not work on at least 3 drives I tried

On a positive not we have step and direction working from Mach 3 and GDtool

Hope this makes sence to you

Regards

Tim P.S cant see where you attach files on this !!!!!!!!!!

[Al_The_Man]

I will look it over and see if I see anything.
If you Go Advanced when you post, you can make attachments.
