Fanuc coder pin outs.

Re- Howa NC7 Lathe, Centroid Retrofit, Serial #A900365
I will need to fit 9 pin plugs to the wires coming from my axis pulse coders. The X & Z axis Pulse coders are Fanuc type 0300 - T001. We also have spares off a machine we wrecked, a younger machine, that are Type A860-0 300 - T001.

The Z coder has a junction box where the wires are connected, marked from the top down S4, S3, S2, S1, then R2, R1, then the over temp switch on, OTL2 and OTL1, then G3, G2, G1. This is wired to a Honda plug, which was connected to the old Fanuc T5 controller. The R1 & R2 have 3 pin connections each on the Honda plug, the others 1, except R2, which is not connected.

The X coder has a Canon plug outlet, going to a Honda plug which was connected to the old Fanuc T5 controller. The Canon plug is a 17 pin, marked A to H, J to N, P, R, S, T. Of these, A, B, C, D, E, F, G, & H are connected to the Honda plug. Also R & S which are the over temp switch.

This gives us an uneven number of wires, even more so, with R1 & R2 having 3 wires each on the Z motor coder.
Any suggestions as how to move forward from here, with the identification of the wires will be appreciated.

Also doing my bench testing of the MPU 11, GP104D and computer, I can't get the outputs 17 to 20 on, even though I seem to have the correct jumpers in place. There are messages saying door open and emergency stop detected. I have my input lights on for where I have put the jumpers, but my outputs are 6, 11, and 18. When I press F3, I get screen flashing, and no change to the output lights.

All help will be much appreciated and I will publish my finished details on here, with as much help for others as I can, once we have it going.

Cheers, Colin

Colin,

Please send us photos of the nameplates encoders in question.

Regarding your enable outputs (out17-20), If you don't even have your encoders connected yet you are getting ahead of yourself. Those outputs won't come on if you have ANY faults -this includes encoder faults of any type. Try to go into MDI, if it kicks you right back out it's because you have a fault of some type.

Colin ,
Following step need to be done before out17 and out18 to become high

1) Connect Encoder to Mpu11
2) connect Drive fault in17 and inp18 (for testing normally we make it high but on running Driveok signal will connect on inp17)
3) you need to set the right plc program for it which plc prgram you hav now .

4) you need also ip1 ,inp2 ,inp3 and inp4 limit inputs to become high .
5) you also need your lube input to high.

I hope this will helpful to you
