Need Help!- Electro Craft Servo Wiring

[Loren1]

Need a wiring diagram for a Electro Craft Servo. The name Reliant Electric is on the other side of the lable.

P/N 0242-02-013; Model No. E242
It has eight wires. The Large Red and Black wires I know. The others are smaller with the colors; Yellow, Blue, White, Red, Green, Black

Thanks

Depends on if it is a factory or after market encoder.
If Factory colours:
Red +5
Blk common
White A
Yellow /A
Green B
Blue /B
With no marker pulse.
If Renco it could be different but a meter or a 'scope would tell you the whole story.

Thanks for the help

I don't know what the "/" means before each letter in the color code examples you gave.

[Loren1]

I know some electroic tecks at work they have equipment to help me. I would need to be able to tell them what I need for readings?

Would a multi-meter work? I stil need to know the reading for the different wires?

[Al_The_Man]

The "/" means the complement of the other, you can do it with a meter but it is tricky, you have to turn the shaft as slow as you possibly can.
Use a voltmeter with respect to the black -ve, you should see a alternating high and low on each line when turning slowly, the A & /A B & /B will be exactly opposite to each other, the A`s and b`s will be offset from each other.
The pdf shows the marker pulse which you may not have if I am right.

The drawing of the motor in the diagram looks different than what I have. Would a picture of my motor help? Also the wiring color code on table 3, lists ORN (Orange) BRN (Brown). I have smaller gage wires Black and Red, there are no ORN or BRN colored wires.

[Al_The_Man]

There is no motor in the PDF, just the encoder, It is a Renco, Ignore the wiring details, I just used it as an example of what you will see as encoder pulses.

Any ideas what wires I would use if the servo motor has an aftermarket encoder?

[Al_The_Man]

It depends what make, but if you look at the chart 2 in the PDF, the Renco happens to be the same wire colour as the previous one I posted for the stock encoder, if you ignore the marker or Z pulse outputs..
You can pretty much bank on red for + and Blk for -v.
The rest you would have to confirm.

OK. I probably should have said my electrical wiring back ground is limited to a 1965 VW Bug schematic. Without the radio option.

I don't anything in the PDF marked CHART. There is a table 2 but it looks like measurements for shaft dimensions. Table 3 has wiring information but I don't see anything with MARKER or Z PULSE outputs

I was looking for information to match "The CNC Cookbook" page 215, that has the Motor Drive controller diagram. It uses INC+, ENC-, Phase A, Phase B for the wires from the motor. If I understand the book?

Is CH the same as Phase? ENC is a complete unknown to me.

[Al_The_Man]

OK I erred. the colours are shown in Table 3. 1st page of the PDF.
The signal pattern is in the lower left side of the page, the Z is shown as Index.
ENC + is possibly +5v supply?
CH is usually the same as phase.
The main thing is to use red and black as supply and the other four are probably the A & B Pulses.

[Loren1]

Will I need a ENC+ or - wire to go with the A or B pulse. IE: A pulse and a ENC+ to go with it? Is this where I use the complement method you discribed earlier?
