Hello,
For wiring motors, it is written as the following:
AA AA# AB AB# ZA ZA# ZB ZB# etc
is this mark # that means + ?
thanks a lot

Robhi,
What type of driver are you using? Also are the motors bipolar or unipolar? There is no real +/- with steppers, if they go the wrong way either switch one pair of leads or invert the direction in the software.

That all what I can say, I am a taxi driver , so I let you imagine the rest..
Thank in advance for your help

Robhi,
Do you have a link to the website with the motor wiring so I may advise on the wire combinations?

Hi, sorry to answer you so late , I was some place where had no connection..
the link for the motors is http://www.arceurotrade.co.uk/Catalogue/Stepper-Motors
and mines are :-
Code 160-010-00400
Type Hybrid Stepper
Holding Torque 220Ncm
Step Angle 1.8°
Rated Voltage 7.5V
Rated Current 2.5A/Phase
No. of Wires 8
Size 57x57x115mm
Shaft Dia. 10mm
Shaft Length (Front) 30mm
Shaft Length (Rear) 30mm
Net Weight 1.74kg
I would like to wire them in bipolar series with my drive :-
Four axis bipolar drive
±2.5 Amp/Phase PWM controlled drives
up to 35 Volt (w/BEMF)
FULL, HALF, QUARTER, & EIGHTH step/Full Step
Built-in DC-DC Converter for 5 Volt Logic
Filtered and Buffered STEP & DIR Signals
Built-in Break-out:Screw Terminals for Unused Parallel Port I/O
Synchronous Rectification
Internal UVLO and Thermal Shutdown circuitry
Easy connect for most popular Step/Direction control software
Small Size: 5.65" X 2.85"
I hope this will be the right answer
thanks a lot

Robhi,
The data sheet for that motor shows the connections for series bipolar on page two, For BIPOLAR SERIES:
Join YELLOW A to BLUE C and insulate connection
Join PURPLE B to BROWN D and insulate connection
Winding One then equals RED and BLACK
Winding Two then equals WHITE and GREEN
You should be OK with that setup.

Hi,
Thank you for your answer,
jouster one more thing please, on the drive it is written as this :
ZA ZA# ZB ZB#
the place where I have to wire the motors. I don not how to wire them and which wire goes to this place or another...
thank you again for your answer.

Connect either red and black to ZA and ZA# and the white and green to ZB and ZB#, if the motors turn in the wrong direction just reverse one pair (red/black for example)

I use exactly the same motors.
The stepper motors have 8 wires - this means that they have 4 coils - two North/South and two East/West.
Your stepper motor driver boards only have four wires, so you must wire the coils together, the North/South together and the East/West tpgether.
You can do this by wiring them in series or in parrallel.
In series the motors will use less current - but not be as powerful. (Wire up as Kirsten says)
In parrallel they will be more powerful, but use more current. (see below)
These motors are rated at 2.5 amps at 7.5 volts - but that is for one coil. I use(d) 24 volts to drive them, and wired them in series. The drives I used were rated at 2.5 amps. This got me going - but I later found that the motors would not give me enough speed.
I connected them in parrallel AC - A#C# and BD - B#D#. The only trouble was that this method required about 4 amps to drive it and the drives were only 2.5amps. I changed to Gheko drives. The difference is fantastic - my speed before was about 4 ins per minute (steel cutting lathe), now I could get up to 40" per minute - a 10 times increase. I have settled in the high 20's for accuracy. I have now increased the drive voltage to 36 volts.
Just a quick word of warning - reading your post - the drives you have chosen seem to say they are PWM drive. Mach 3 does not use PWM control - it uses step and direction pulses to control the axis motors.
Before you buy them just check that they have a step/direction input to them - not a direction/PWM

Hello,
thank you so much, you have helped me à lot.. I appreciate You as well your replies.
Sorry for replying to late..

Hello again,
Sorry to bother You, I have already bought the motors, and the drive as well..
To Jimpinder, Could you tell me which drive you use Gecko drive.. ? they are a lot of drives that have this name..
i guess that am going to do the same this as you, that will help me a lot.. also if I can use my motors with this drive.
thank you
Robhi

G201,G202, G203, G210 and G212 are the stepper drives from Gecko.
The 201,202,203 are fixed at 10 microsteps the 210,212 have full, half 5 and 10.
Best bet for you I would think would be to stick to the 201,202,203. Probably actually 201 or 202 would be ones I would go for.

Thank You Hood,
So all what I need is to buy the G203V. that Will be enough to drive my 3 motors? or I have to buy other things beside the G203V?
Robhi
-
You will need 1 drive for each motor you have.
Hood
-
So I need 3 drives for my 3 motors.. is OK..
these 3 drives will be connected to gother ? is there any site which illustrate , explain how I can do that?
Sorry I may make you laughing.. but never mind
Robhi
-
No laughing here, only time I laugh is when people dont ask questions :)
Heres how things work
Your parallel port cable comes from the computer, it connects to a breakout board (can just solder direct to cable but breakout is better) Then the drives connect via Step and Direction pins to the breakout. The motors connect to the drives and also a power supply connects to the drives. Limit switches and other I/O you may have connect to the breakout board.
For the Geckos a power supply of between 24 and 80V DC is needed, they are easy enough to make, I will post a link in a few mins to a pdf that tells you how. The more voltage you supply (80v max) the faster you will manage to get your motors turning :)

OK heres the link to the power supply building pdf.

Oh meant to ask, where are you from Robhi?
Hood

Thank you ,
I am from palestine, but I live in Switzerland since long time.
thank you again Hood
Robhi

No problems :)
Hood

Robhi
just looked back at your earlier posts and the drives you have will probably do, they accept step/direction input and that is what Mach puts out.
Geckos would get you moving faster probably but on a small machne it may not be needed :)
Hood
-
OK ... I am going to do so, hoping it will work.. if not never mind..
thank you again , have a nice night

Sorry I missed this post the last time I was on the net. Hood has given you good advice - is he says the drives you have bought also do step and direction pulses, then use the drives you have bought to get started, You can wire them in parrallel if you wish, the drive is linited to 2.5amp so will not give you full speed/torque but will be better than wired in series.
The drives I use are the Gecko 201 - the simplest one you can buy. If one of your drives fails, then buy a Gecko to replace it.
Best of luck
