Vexta 5 phase drives wiring colors

[MonoNeuron]

Hi guys,
Just been wiring up some 5 phase Vexta steppers to a couple of drives that aren't matched to the motors.
I have a wave drive geared head stepper and a couple of size 23's and a 32 stepper all 5 phase.
I bought a couple of UDX5128 and a couple of CSD5807 5 phase drives from various places and then noticed that the wire color code was different with the older setups.
I ended up working out the coding and just wanted to post it up here for others to save them an evening of stuffing about. The color code is printed on the circuit board or on the case so just transpose the colors with the one listed next to it.

For the CSD5807 compatible motor to the UDX5128 drive ......

Green - Blue
Red - Red
Black - White
Orange - Brown
Blue - Black

You can swap the wires back for the other type of drive so it then looks like...

For the CSD5807 Drive to the UDX5128 compatible motor you get

Blue - Black
Red - Red
Orange - Brown
Green - Blue
Black - White

Now.
Using the size 32 stepper on the CSD5807 I was only able to get about 450 revs of usable power/torque but when the same motor was connected to the UDX5128 I could get about 1300 revs of usable power.
The UDX5128 is a high speed drive and really shows what it can do for the larger motor which isn't a high speed one.
The CSD5807 drive was able to spin the size 23 steppers to about 2160 revs but power fell off rapidly at the upper scale. If you were to use the extra speed for rapids then the usable revs would probably be around 1500 provided you have a low friction table etc
Just goes to show the extra size and larger rotor inertia isn't alway an advantage if you want to go fast. It was less than half the revs.
I hope this helps somewhat as there isn't a lot of info here on 5 phase stepper drives but there is more and more 5 phase drives starting to dribble onto the market now and some are very nice units.

can you conect tellme how to conet the udx5128 to the computer?

your right wiring is very simple, but in match 3 need to activate speed low under motor port and pins, wihtout activate the motor dosen't move


i have this one to do you have any information about?

sorry I misread the post.
The drives, as you already know, are Yaskawa stepper drives but I haven't been able to source any info on them either.
Maybe you could email the company for a manual, but in my dealings with large corporations, you won't exist to them.
It's listed on one web site as a speed control box but that's it from me.
Sorry.
Rich.
