Test Drive Quanser QNET modules with NI ELVIS II - and more

Traditionally, NIWeek gives us a great opportunity to highlight seamless integration of Quanser experiments with National Instruments hardware and software. This year, you can test drive some of the latest innovations Quanser is presenting at NIWeek 2009 in Austin:

Quanser Engineering Trainers for NI ELVIS (QNETs) extend the functionality of NI ELVIS and LabVIEW software and increase the value of your investment in NI platforms. Six different experiments for one platform give your students hands-on experience in the important aspects of engineering practice: control, design and simulation. Try all six boards and imagine how easy teaching control fundamentals can be. Find out which experiments are the best suited for your discipline - whether it is electrical, mechanical, mechatronics, aerospace or biomedical engineering.

Active Suspension with CompactRIO: integration with National Instruments hardware provides many options for prototyping, hardware-in-the-loop tests, or final implementation. Portable, configurable and simple to set up, while achieving high performance and reliability - Active Suspension with CompactRio brings real-world engineering into your lab.

Visit NIWeek 2009 Academic Forum to learn more about classroom innovations! And visit Quanser in the booth 807 - our engineers are ready to answer all your questions!

please, we bought QNET DC Motor and I would want to know how the encoder wires(on the DC Motor) are connected to the Digital Input of the DAQ channel 0 of the ELVIS. This is to allow me to modify the accompanied VIs so that the experiments can fit into our curriculum

QNET DCMCT Encoder connections:
Enc Dir to DI #6
Enc Clk to CTR0.

Thus Digital Input #6 is used for the direction and the CTR0 counter is used to count the number of edges.

I want to measure the DCMCT motors stall current. Can I do this by holding the rotor static and giving the motor voltage? Is this safe, can the motor control circuitry sustain the high current that will flow through it?

Mitch said...

It is safe to stall the motor and measure the current as long as you don't supply an input motor voltage over +/- 5 V.

Note that the amplifier has a gain of 2.3 V/V. In the supplied QNET VIs, the voltage is divided by 2.3 so the voltage commanded from the VI is the voltage applied to the motor leads. Be careful with this if you are designing your own VI.
