And this is probably the reason why I can’t seems to get the thing working?

The deceleration rate is equal to the acceleration rate. The trapezoidal velocity profile generator computes the de. I am l629 Taiwan too. Design Requirement for my part.

LM from Texas Instruments

That’s the reason why I insist on sticking with LM How could I better troubleshoot the problem? If there are disturbances to the motion.

While the SXes will tolerate 30ma, less is better.

So the reason you are trying to recommend 32bit Propeller over 8-bit Stamp is because with 8-bit Stamp, it is not fast enough to be compatible with the faster LM that work better with bit micro-P. Internet is down due to Taiwan Earthquake!!! So you get more speed and simpler code.


Precision Motion Controller

Still, I was wondering what is preventing the stamp from communicating effectively with the motor controller. That is where you might find a steep learning curve.

I am sure it will be a rewarding addition. What is wrong here? The velocity is maintained by advancing the desired position.

It will tolerate 5. Or during the micro-P selection, I have to go with one based on a 16bit core. The user guide was not very clear with the interfacing.

The LM uses this infor- mation to affect the move by accelerating as specified until the maximum velocity is reached or until deceleration must begin to stop at the specified final position. I have attached a copy of the LD chip for your inspection. Datasueet I killed LM because I connected a motor and power up? Sometimes, it jump to lm269 hex00 or hex The velocity is maintained by advancing the desired position at a constant rate.


Use a single power supply of 32V, 1A which splits to two set of power and ground lines. As shown by the status, it is staying at hex Home – IC Supply – Link.

On one set, drop the voltage to 5V through 2 stages of voltage regulators 24V, then 5V. Please bear with me and help me solve the problem. I know there is too many questions here.

When operating in the velocity mode, the motor accelerates. I managed to find a pc with a faster internet access not through the phone line and looked at the datasheet for L It is really fustrating to be working on something for datawheet few weeks and then find that it does not work out.

It is only providing a brige ciruit like a LMD, but no motion control in place.
