R2020 Rutex connected to Siemens motors.

[Darc]

Hi,
Firstly I'm moderately confident with stepper motors, I just haven't had much to do with servo's, so what better time to learn.
Could I get some advise at to where/how I should connect the terminals onto the Rutex R2020 servo drive I've got, I understand the basics, it's just that the terminals on the motors have wires that I don't understand.
For example in the encoder connection there is 2 red, 2 black, 2 yellow and 2 blue wires they just have 0.5 written next to them, not sure what this means.
I understand the A,A+(I assume that's what the asterix means) B,B+ is.
But I don't understand what the R, R+ and the W, W+ is. Any ideas?
Also is an image of the motor connectors, thae last 2 wires are not attached (Actual Speed, Direction wires).
I was going to ask about the motor connection but I just noticed on the R20x0 sheet it says R2010only. Well that's helpful considering it's the R2020.pdf help sheet.
So any advise anyone could give would be muchly appreciated.
Thanks

R looks like reference or marker pulse (1/rev?) and the W says contamination signal, this is often a error signal fed back from the encoder, heidenhain encoders often have this.
My guess anyway.

Hi Al,
Thanks for the response, I'm just confused with what terminals I need on the RJ45 connection on the rutex.
It has the following:

Ch -A (non inv.)
Ch -A (inv.)
Ch -B (non inv.)
Ch -B (inv.)
Ch -I (non inv.)
Ch -I (inv.)
+5v
0v/Signal Ground

So in theory either the Reference pulse or the contamination signal terminals go to the Ch -I (non inv.) and Ch -I (inv.) connection???
Also is the (inv.) the positive terminal and the (non inv.) the negative terminal?
Am I even close?

Does anyone have a connection diagram for the Rutex R2020 motor connections?

[Al_The_Man]

The Ch-I's are the Index pulse or reference pulse, you can probabally leave the contamination signal unconnected, is the encoder a heidenhain by any chance?
I just noticed that the diagram describes a linear scale pin-out?

[Darc]

Thanks Al, that makes sense to me now, I didn't realise that the Index Pulse and Reference pulse was the same thing.
I'm not sure if it's a heidenhain encoder, even though it's a Siemens motor do they all use different brand parts?
I can't find the linear scale out you mentioned, does this need to be connected as well?

[Al_The_Man]

Its just that the diagram you posted refers to EXE60 linear measuring unit which is a Heidenhein scale and interface.
It maybe a general connection diagram that covers many applications.

Well it turns out that the diagram for the motor is the same for the R2010 & the R2020.
So on the rutex it has the following:

Pin #1 +Vm DC Motor supply positive
Pin #2 0V DC Motor supply return
Pin #3 Mot.1 Motor terminal 1
Pin #4 Mot.2 Motor Terminal 2

On the servo motor it has the following terminals:

Control voltage +24v
Speed Controller enable
Set speed, non-drive end
Set speed
Actual Speed, non-drive end
Actual speed

So I've got 4 terminals on the rutex, and 6 on the motor.
So I need to work out which one's I don't need.
Thanks again (still)

According to the diagram that is not motor connections but Siemens servo drive connections, I don't see any motor details on the connection sheets.

Sorry I should of explained myself, I can't find any diagrams for the motors (not even siemens could help me) but I found some for the drive that they are attached to.
So I was trying to work backwards to figure out what wires are what.
Did that make any sense at all?

[Al_The_Man]

I am assuming it is a DC motor, so apart from the encoder, there should be two large conductor armature wires, and if it is fitted with a tach, two smaller wires, that you do not need if Rutex drives operate in the torque mode.
If You also find two other small wires, and if they show very low resistance (dead short) these could be a thermal detector.
Confirm first it is in fact a DC motor.

I will ask our electrical man to have a look, but this is what's written on the motor.

Can't really tell if it is DC, but It looks like it has a tach and a Heidenhain ROD320 encoder 2000p/rev. Does it have a set of large brush holders on the rear end, apart from the tach which are smaller?
