I am retrofitting a 2003, Haas TM-1. The original motors are Yaskawa X & Y are 450w, medium inertia, Z is an 850w, brake, medium inertia, all motors are 130mm mount. So, going with the DMM, I plan on using the 1kw, 130mm motors. I plan on using the Oak board. I looked at using Yaskawa drives, bu...

I getting ready to order DMM Drives and Motors. But what encoder options do you recommend?

Marty, what did you use on your Fadal?

Hi Marty. I am glad that you are not having issues with the DMM drives. I have a Haas TM-1 and have not selected the drives yet. But I was staying away from these drives because of the amount of problems that I been seeing here and on other posts. But, seeing that you are not having problems, I may ...

Did you check to see if you are getting a momentary voltage drop when things happen? Also, DC power supplies when power is applied, draw a huge amount of amperage. This can cause problems, so the power should be applied only when the circuit breaker is turned on.

The one that you got should be fine. The 27 ohm resistor is the one that I was going to recommend, but there is about a 30% duty cycle on that one. For higher duty cycle you would need more stuff for the drive. Since Automation Direct is a distributor for WEG, they could have gotten the resistor for...

"Ihave a WEG CFW-08 10AMP VFD that"

What is the exact part number of the drive? It makes a difference what resistor you use.

As an update; Z axis motor has a bad encoder. Works fine CCW but CW quits after 100rpms.

Your text (2a) Yes, that is correct. I missed a step in my explaination. (3) & (3A) Yes, X only. (4a) Yes, both Y and Z came on (5a) Yes, it fights. (5b) I cannot turn it and there is no errors or red bar "Do you mean that the problem stays with the Z servo motor; the Z cable; or the Z driv...

I am setting up a new board and X and Y axis work fine. However, I can't get the Z axis to work. Upon Estop release, power comes on to all 3 motors and they are holding position. Using ether the MPG or the VCP, jog works for both the X and Y but not for Z. If I run a job, the program will run, but Z...

Hi Rmillerauto I am an industrial controls systems engineer for the last 30 years. I am presently doing about the same thing with a 2004 HAAS TM-1. First of all, the spindle can be run with a single phase VFD, (Check out Polyspeed drives) vector drive is not needed. There is an encoder that will fee...
