And this is probably the reason why I can’t seems to get the thing working? LM is still giving a response, just not the one I expect.

At any time during the. It is really fustrating to be working on something for a few weeks and then find that it does not work out. Figure 10 illustrates two typical trapezoidal ve- locity profiles.

Quick Links Categories Recent Discussions. I managed to find a pc with a faster internet access not through the phone line and looked at the datasheet for L Thanks for the reply.


Still, I was wondering what is preventing the stamp from communicating effectively with the motor controller. If the motor is unable to maintain the. I’ve always had good luck with motor controllers like the L, but you’ve not been all that specific about your exact needs. If the motor is unable to maintain the specified velocity which could be caused by a locked rotor, 9 datashheet.

Initially seems a little ok,but after a couple of runs the nightmare seems to reappear. So you get more speed and simpler code. When operating in the velocity mode, the motor accelerates.

It can be done, but twice as slow at the same clock speed. What is wrong here? Internet is down due to Taiwan Earthquake!!!

I suspect I actually cooked the LM, but no smell dwtasheet sign of being cooked. You can either build a 16bit wide output with two bytes or go with a 16bit or 32bit processor.

As shown by the status, it is staying at hex If I were to connect a 8Mhz clock and power up, then the return status byte would be FF. But, it is not as precise a controller as the LM That is where you might find a steep learning curve. The whole uP can only withstand ma at one time. This one supplies to the LMD Sometimes, it jump to maybe hex00 or hex The deceleration rate is equal to the acceleration rate.


I am in Taiwan too. It is the same problem as the BasicStamp2px. Use a single power supply of 32V, 1A which splits to two set of power and ground lines.

Precision Motion Controller

It is crazy to depend only on oscilloscope and try to imagine what is actually happening. The LM uses this infor. Will consider this as one of the option if the learning curve is not that steep and development time is short.
