Teknic SST-3000 Drives

[jeoffrey]

Hello,

Is it possible to use a 48V dc servo motor on a Teknic SST-3000 drive?
If it's possible, how do i have to hook the motor, encoder, the parallel port from the PC to make it work with Mach3.
I don't have a manual of this drive and I'm an absolute beginner with servo motors.

Thanks,

Jeoffrey

Try this and see if it might help some

Oh and to get Mach3 signal to the drivers you need something of this sort http://www.pmdx.com/PMDX-120/index.html
I'm really new to this... but I think it should work

Thanks Wolfmetalfab.

I allready downloaded that manual but it's not exactly the same drive, so I'm not sure about the wiring. IS it possible to use a normal DC servomotor with 2 wires on this drive? On their schematics you always see 3 wires + shield.

About your mach3 signals, can't I use the normal step - dir signals from the printerport directly on the step - dir inputs of the drive?

[wolfmetalfab]

no idea if you can use a brushed motor on a OEM driver system, as for the Mach3 signals, I'm not sure off hand if you can, but if it would work I would still atleast put a opti-isolator between the computer and driver (esp seeing its a OEM)

(I could be wrong tho, only been deeply looking in to the CNC stuff for a week now)

Does the drive take step/dir signals? You need to make sure it will do that.

otherwize a lot of times, its just better to get yourself a geckodrive for bushed servos.

looking at the manual says

The SSt-6000/3100 servo drive can be commanded from standard digital step and direction positioning signals or a standard +/-10V analog command signal from a servo controller

so it seems that you could step/dir it or pixie it to make it work

[jeoffrey]

Yes, you can send step/dir signals directly to the drive.
What I can't do is to enable the drive. Do I have to use the enable pin and the shutdown pin on the drive?

[cncpro]

Yes, you will have to send an enable signal to the enable pin. You will also need to configure the drive using Quickset. Download it here. In the manual you downloaded, it describes how to make the serial cable that links your pc to the diagnostics port of the drive. Once hooked up and powered on, assuming everything is working, Quickset will show an "online" status and "enabled" status. You access the motor setup page by pressing <ctrl><shift>m. You can specify that it is a brush motor there and define the line count of your encoder. Then just follow the tuning procedures in the manual.

I think for a brush motor you hook the power leads to the "R" and "S" pins at the drive.

Thank you very much Joe.
I will try this as soon as possible, and let you know if it works on this forum.
Just give me a couple of days to test.

I have three sst3000's on my Bridgeport with Camsoft system. I have so far managed to cut some paths in wood, but I'm having trouble getting the motors tuned properly. The motors are DC brushed from an alilam control. I am using the original linear scales on the ways rather than encoders on the motors, and I don't think I have enough resolution to get the motors tuned properly. I have to run it very sluggish.

Still working it out. I've taken a break from it while working on other projects but will be back on it soon.

I plan on running the spindle motor with an encoder and an SST 6000. We'll see how well that works. Maybe I'll end up using a high powered servo for the spindle rather than the original 3ph motor.

The SST3000 only takes step-direction and will not run on +-10v if you have the OEM units off of e-bay.

Hello Z28YOUUP,

Happy to know somebody else is using these drives.
Do you have a manual for the SST-3000 because at TEKNIC they don't support them anymore, so they will not help me to make them work.

Also, do you have some schematics of how you wired them on your Bridgeport, and how you have to make the cable to configure the drive?

Thank you,

Jeoffrey
