Millaisella askelluksella tuo ohjain toimii ? Eipä tuota tekstiä oikeen ymmärrä...

Vaikea sanoa askel jakoa, mutta jos oikein muistan niin CNCzonella oli jossakin jotakin juttua tuosta ohjaimesta...
Se on viellä jonkinlaisena proto/koe versiona myynnissä unkarissa ja siksi sitä ei kai vielä löydy Englannin kieliseltä myynti sivulta...

Helpoimmalla varmaan selviää kun pistää meiliä tuonne valmistajalle ja kysyy niiltä, ellei jaksa ruveta zonelta etsii artikkeleja...

Hi,

No, our servo controller is only able to run brush servomotors, not steppers.
We have a 3 axis steppermotor controller, but I don't have the manual in English(translation in progress), we only sold the steppermotor controller in Hungary, yet. It's a well tested controller, we sold out more then 100 pieces in our country. It supports full and half stepping mode and can be configured from the PC.

If you're interested, take a look at: http://hun.cncdrive.com/hun/step1.htm
The site is in hungarian language, only the picture can be interesting for non Hungarian speaking people.

Eli näyttää toimivan koko ja puoli askelluksella... Laite on kai PC:llä konffattavissa jotenkin???

Yes, we have a steppermotor controller.
This controller is an old design, I personally designed it around 6 years ago and sold out many pieces, it's popular at Hungary. :)

When I designed this controller there where no high capability microcontrollers and we have used an open loop current control technic in the controller.
At that time as I remember there where no other concurency than Gecko. :)
The drive is not as easy to setup as in most of new stepper drives.

Under open loop I mean, you cannot set the current to a value, the controller has 3 parameters:

-step-in time
-holding duty
-full/half stepping mode

You know, in steppers when you apply constant Voltage to the coil, current will flow in it, caused by the RL property of the coil current will increase in time.
We used a technic, that the user can set the maximum time allowed to feed the coil with maximum Voltage.
When this time expires after the motor step into a new position(this time is in the milliseconds interval) the controller turns off current and go into an idle state.

In the idle state, it applies a PWM to the coil with a user defined "holding duty" cycle PWM.
This PWM should be set to feed the coil with around 50% of the rated current to keep the shaft is place but do not overheat the motor or the drive.

To make these settings a minimum requirement is a multimeter which can measure current.

The drive is compact and can control 3-axis and has a relay control.
It knows full and half stepping modes.

There are some problems:

1.) There's no english version of the configuration software nor english manual written, but there are only 3 parameters, which you hopefully understood from the above explanation.
2.) I cannot garantee that it will work with this high power motor.

The maximum motor size which I have tested it was a 6Amp motor at 30VDC.
One of our customer is using these controllers is his workshop with 28Nm steppers, but I personally cannot give you any warranty for correct operation with your high power motors.

Pitäisikö kokeilla, vai tilata ne Geckot? Ainakin ohjaimet ovat valovuosia edellä BP:n alkuperäisiä...

Sanoisin että jos ei ole rahasta kiinni niin ota Gecko:t... Ovat nopeampia ja monipuolisempia kuin tuo unkarin ihme... Mutta budjetti luokan harrastelijoille ja ns kakkos konen tms tekijöille tuo unkarilainen ohjain on hintansa ja tehonsa puolesta varmaan ihan Ok...
