trinmaic (GAP)

[Joachim_Kranzen]

Hello,

I try to control a stepper motor via a trinamic board.

Now I have to get the actual position (trinamic-short: GAP) for positioning the stepper.

Does anybody know how to implement the GAP command in LabVIEW?

VIs?

Hi Joachim,

unfortunately there are no drivers for the Trinamic´s boards available in our Instrument Driver Network.

Depending on the interface you are using (I2C, CAN, ...) you will have to create your own VIs

sending the commands to the motor driver board.

Alternatively contact the Trinamic's support for a LabVIEW driver - many companies have drivers

or even create some if enough requests are sent in.

If you're using serial communication, the Trinamic control set is fairly easy to implement. I recently did so in C#; the code in LabVIEW wouldn't be difficult.

I solved the problem another way, using time differences. Therefore I don't need to know the position of the motor via GAP.

Thanks to all.
