Can you post a picture of your wiring?
Hi freind,
The servo motor been short circuit.
That puzzle me.
I think i follow the wiring diagram exactly.
I need an advice.

I don't see any obvious wiring errors. With the power on, are you getting 230V across R and S, and across L1 and L2? Do you have 230V to your breaker?
You have not Main Power supply Ground or Motor Ground connected you also don't have the Logic power filter or protection in placeQuote:

What is your max Voltage supply ???
Hi mactec54,
Thank you for your prompt reply.
My maximun voltage is 240v.
I will try your advice.
I really apreciate your help.
Thank you

The Power filter and protection for the logic wiring won't change anything, it's just a requirement once you do the installQuote:

As usually i need you advice on my cnc retrofit.
The problem is the z axis.
I mounted the dmm servo motor with brake on the the z axis.
I use 24v power supply only for the brake itself.
The problem is when i turn on the computer and mach 3 software
THEN i turn on the servo motor it drop down.
Im using the 30mm ballscrew,1 kw with brake dmn AC servo motor.
Is it the software setting in mach3 or tuning servo motor in dmm tuning software that i miss.
Thank you mactec54.https://uploads.tapatalk-cdn.com/202...6d6027d5ef.jpghttps://uploads.tapatalk-cdn.com/202...520b9a3794.jpghttps://uploads.tapatalk-cdn.com/202...e23e80bf67.jpghttps://uploads.tapatalk-cdn.com/202...4412371703.jpghttps://uploads.tapatalk-cdn.com/202...da29c875a5.jpg

When the servo is energized the brake should release if the servo can not hold the load, it may be tuning try and add some more Gain but this must be a balance of the 3 settingsQuote:

maybe output of servo (U,V,W) damge.

One engineering mistake in my book is aluminum spiral motor couplings, I reserve these for encoders.
For motor drive, you are better off with stainless versions for durability.IMO.

Any particular type of coupler that you would recommend?

The same version, but in stainless, if you are going to use the existing ones i suggest you get a couple of spares, you may need them. .;)

Noted .1 bought 4 of it.1 got one spare.Quote:

... multivariate of how to do the job for sure. Engineers have many choices

Do you have any wiring diagrams of your setup? may help Color code?

So the the problem which i had is solve.
I used to work with stepper motor never with servo motor.
Now the problem is when i switch off the computer , mach 3 and the servo power everything stand still until i turn the computer, i turn on mach 3 , i push the reset button on mach 3.the z axis drop.
Luckily it have the stopper if not the ball bearing going to spread on the floor.
I already power the servo brake with 24v 3a.
Just that i need a advice on the servo motor diagram , how to wire it properly, or as long that the z axis wont fall.
Thank you.

When you hit the Estop the Power should then be turned off for the Brake, Power should be off the Brake all the time until the servo main Power is turned onQuote:

That is a heavy head I'm surprised it does not have a counter weight to balance the load
