Breakout board design published

Hi Folks,

I just uploaded an example design of breakout board for VSD-A drive. Check it out at http://granitedevices.fi/index.php?id=16

Breakout design got just upgraded to Rev2. Get it from:
http://granitedevices.fi/index.php?q=servo-drive-vsda

Also firmware version upgraded to 1.14 for optimum breakout operation.

What do you folks think, should we get a bunch of PCB's to be sold or distributed with drives?

That looks really good. Where can I get one?

Hi.

I am just a hobbyist, maybe this is not a practical idea.

Hobbyist like me have sometimes no idea when the servo motor is overloaded.
I was thinking of putting temperature sensors on the servo motors.
When the temperature gets to high a emergency stop is triggered.
The temperature sensor like LM35 needs some extra electronics.
Would it be sensible idea to put the electronics for the temperature sensors on the breakout board ?
Or would this be over designing, would a separate board for this be better ? :-)

[Xerxes]

Many motors have integrated temperature sensors in windings and some drives may support them directly.

However, you could just install bimetallic thermostat on motor surface and connect it to estop or some other breakout board input like any other switch. No added electronics needed.

Neat board, I like how it has logic for the fault output from the drives, allows to be used for servo as well as a stepper system, I may print one out and give it a go, nice work and thanks for sharing.

How much would you sell the finished board for? I am sure it will work out cheaper than me spending a couple of hours at home on the weekend...

Russell, we sell PCB for 7 eur. It can be hand-assembled in 15 minutes if you have parts available.
No assembled boards are available since they would be expensive to manufacture industrially in small volumes.

Hello folks, my first post here.

I wonder if anyone has used succesfully other BO boards with GD drives?

I've started to build a four axis system with VSD-A and I would need some extra Ins and Outs for relays. Since there's so much to do for one person I'd rather pay a few bucks to get a ready board. Would appreciate all recommendations.

Thanks,
Risto

PS. I think I may have seen a post from Tero telling that there will be a finished breakout board by GD. Can't find that post now, did I read right?

Yes, many have used CNC4PC boards with them. Any step/dir board should do. However most of them don't utilize the fault signal from drive I think.

The assembled BOB's will be for VSD-E drive. 50 pcs of them have been already ordered from factory.

Thanks Xerxes,

Have you considered spindle speed control with the new BOB?

What also comes to mind is that if the VSD-E can handle sinusoidal AC motors, is it so that one VSD-E could be used instead of a vsd unit to control the spindle speed (1-phase 220V AC motor)?

There is one digital output that can drive relay or for example PWM or pulse frequency to spindle.

VSD-E will drive all kinds of permanent manget motors (1,2 or 3 phase). Induction motors are not supported.

OK, thanks mucho. I'll contact you about the twin motor drive later as agreed.
