LM629 DATASHEET PDF

LM is still giving a response, just not the one I expect. Sign In or Register to comment. You certainly will have more speed. 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.

Mibei It is only providing a brige ciruit like a LMD, but no motion control in place. Initially seems a little ok,but after a couple of runs the nightmare seems to reappear. The velocity is maintained by advancing the desired position. Or during the micro-P selection, I have to go with one based on a 16bit core.

Internet is down due to Taiwan Earthquake!!! What is wrong here? The deceleration rate is equal to the acceleration rate. Heard that 6 of the 8 fiber optic underwater channels were damaged. The trapezoidal velocity profile generator computes the de. I have attached a copy of the LD chip for your inspection. I had spent months on it by now.

I managed to find a pc with a faster internet access not through the phone line and looked at the datasheet for L If I were to connect a 8Mhz clock and power up, then the return status byte would be FF. I agree with Bruce that this is not the best device to use with a Stamp because of the number of pins required.

Yes, it appears that not all of the 16bits are used. 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. Can anyone advise how to do it? When operating in the velocity mode, the datasehet accelerates to the specified velocity at the specified acceleration rate and maintains the specified velocity until commanded to stop.

As shown by the status, it is staying at dayasheet I suspect I actually cooked the LM, but no smell and sign of being cooked. The signals are straightforward, should be Stamp compatible. Still, I was wondering what is preventing the stamp from communicating effectively with the motor controller. The Propeller is a 3.

Nature is really messing things up this time. You can either build a 16bit wide output with two bytes or go with a 16bit or 32bit processor. The propeller sure look powerful but is the coding difficult? And in some cases, you might need a 16bit latch to get the timing right. When operating in the velocity mode, the motor accelerates. If the motor is unable to maintain the specified velocity which could be caused by a locked rotor, 9 www.

Should I use two separate power supply for powering ICs and motor? Since the Propeller chip is competatively priced with the BasicStamps, it may be a better fit. How could I better troubleshoot the problem? The velocity is maintained by advancing the desired position at a constant rate.

On one set, drop the voltage to 5V through 2 stages of voltage regulators 24V, then 5V. The whole uP can only withstand ma at one time. That is where you might find a steep learning curve. In the position mode.

As shown by the status, it is staying at hex So you get more speed datasyeet simpler code. The previous LM seems dead. LINUX is just fine. I agree with Bruce that this is not the best device to use with a Stamp because of the number of pins required. Figure 10 illustrates two typical trapezoidal ve- locity profiles.

Use a single power supply of 32V, 1A which splits to two set of dxtasheet and ground lines. I agree with Bruce that this is not the best device datasneet use with a Stamp because of the number of pins required. In the position mode of operation, the host processor specifies acceleration, maxi- mum velocity, and final position. Many successful projects have used the L and similar motor control chips.
