controlling one axis stepper motor via 7344/7334 motion controler

[ptiteuf]

Hello,

Basically, our setup consists of an one axis Zeta stepper motor, a Zeta Drive, an AT6400 4-axis Indexer, and a computer.

However we do not have the AT6400 PC Card which is obsolete (Parker Company does not provide this type of Card anymore).

We would like to know if  we can control the whole system with one of 7344/7334 family motion controllers.

What do you recommend us ?

Are there any other important things need to be considered?

If you need more information, please let me know.

Thank you in advance for your help and support.

Sincerely,

From the little information I could find on Zeta drives, it seems as if will accept step and direction signals, as they are supplied by the NI motor controllers. If these inputs accept TTL level signals the drives can be connected directly to the NI motion controllers without any hardware interface, however for bench tests a device like the UMI box is recommended. It seems as if the indexer you have translates commands from the pc interface board to signals for the driver. I think if you are going to use NI motion controllers you can skip the indexer and control everything with the NI boards. They are quite versatile and probably will offer features similar to the interface board/indexer combo. However, for controlling just one axis with a pc there might be cheaper solutions. There are some devices controlled by commands through the RS232 port and also supplying the step/direction signals required by your driver. Usually these devices are less versatile than the NI motion controllers.

A PCI-7356 motion controller board would be able to controll all your axes (it is a 6 axis contoller - an 8 axis controller is available also).

You would need two UMI's and cables since each UMI (Universal Motion Interface) connects only 4 axes. The two options are the 7774 and 7764

7774 - D sub connections with opto-issolation

7764 - screw termial connector

And, here is a document about connecting 3rd party drives to a UMI:

How do I get the 73xx Controller and UMI 7764 to Drive a Third Party Stepper Motor?

Hopefully this gives you a better idea of how everything would connect - the 735x motion controller would definatley meet your needs from what you have described.

Thank you for this information

Now our setup consists of one axis Zeta stepper motor, a Zeta Drive, and
a computer with NI 7344 controller.
The UMI 7764 would be able to control the whole of our system. We need to buy
the “SH68-C68-S, 68 pin VHDCI & 68 pin.05 series D-type, 2m” plug to connect
the controller to the UMI box.

But we don’t know if we need the “5B Series Power Supply +5 VDC @ 5 A, 220 VAC”?
In which case this accessory is recommended?
We can supply 5 VDC with our own device.
And about “Power cord, U.S. style plug” - What do you recommend us?
Are there any other important things need to be considered?

If you need more information, please let me know.

Thank you in advance for your help.

If you have a well regulated 5VDC power supply which supplies sufficient current for the UMI box and eventual auxiliary devices you can use it.

Since in US they use mains plugs different from the european ones an US style connector probably will be useless for you - if you need the NI power supply. US style connectors have two flat pins. In most european countries you can use power cords with a plug with two round pins.

Alors, bonne chance avec votre moteur pas a pas.

Thank you very much for your reply

 

However, what i mean is - is it necessary to supply current with 5VDC power supply for the UMI (aside from Drive Unit, motor and control board) if we already supply current for Zeta Drive Unit? AC power specifications are 95/132VAC - 50/60Hz for the Driver Unit.

If the answer is yes, what kind of connector do we need to plug in our own power supply to UMI-7764 box?

Thanks so much for your precious help.

Kindly,

Sebastien

Please excuse for bumping in, but is not the Zeta series a motion controller AND drive packaged all in one unit???

Thus no need for the now defunct AT6400 nor the NI 73x4. Just hook it up to the serial port of the PC (up to 99 Zetas can be daisy chained together).

$$ savings and better utilization of equipment. Plus no need to learn a new command set (it uses the native 6000 language)

Hi,

Thank you for replying

I am sorry but it isn't possible in my case.

[Buechsenschuetz]

Yes, the UMI7764 needs its own power supply since there is some active circuitry inside. The 5VDC and GND lines are available on screw terminal blocks so you can hook up any kind of cable you want, you do not need a special connector.

Hi,

I am in Vietnam, I select a P70360 Stepper Drive, but I have a few problems with Power cord, U.S. style plug (777036-01). Have not used in Vietnam?
Please give me some pictures of Power cord, U.S. style plug (777036-01),

Thank.
