L297 Stepper Motor Driver IC

I check the the motor and it needs 6. Why can it be? I have problem with wiring L – Ln. Control input that defines action of chopper. Maybe there is a short from pin 4 on the L to somewhere else.

L – Stepper Motor Controller – STMicroelectronics

Remember Me Forgot Your Password? Than i wired the schematic with leds without Ln than i understood how it works. If an external clock source is used it is injected at this terminal.

Ruby, you might also get more attention if you fatasheet to your top posting, click on Edit, then in the next window click on Advanced, then find the little drop down menu for Prefix and click on Unsolved. Support Home Video Center.

So I am having trouble with a circuit I am building for a stepper motor controller, I am currently following this schematic. Quick Links Categories Recent Discussions.

Page 8 of the datasheet shows how this is used. Output of the on-chip chopper oscillator. I just checked with the multimeter and pin 4 on the l is not short circuiting with anything else on the other pins of both the l and the l That puts a little flag by your title so people know you are asking for help.

Now 2 things remains. Product is in design feasibility stage. I generally use the combination of a fixed resistor in series with a potentiometer. As you can see on the datashest on page 2 of the L datasheet, this is the reference voltage which goes to internal comparators and is compared to the voltages coming from the current-sense resistors.

Who We Are Management. Simple, logic-controlled variable speed fan for fire-fighterbots and other wind-inducing experimentation beans not required. Comments 17 Comments sorted by Date Added Votes. If you find any of the answers here or in any dwtasheet the other questions you have asked useful, you might consider up-voting them.

It’s datashert ready-to-use touch sensor switch compatible with the Grove system. Tut 3, 1 15 Please read the fine datwsheet RTFD and learn what the outputs are used for. Not connecting the Vref pin is probably your most serious problem. Don’t Have an Account? I will need to change my software but at least now the first part is working and more important i understood how it works The motor can be driven in half step, normal and full wave drive modes and on-chip PWM chopper circuits permit switch-mode control of the current in the windings.


There are lots of smart people here and everybody gets to benefit when the answers are out in the open. My question is what are those pins in charge of, their job and what should I connect them to?

Can someone please tell me what did i do wrong? With this pin un-connected, the controller cannot function correctly and it is very possible that it has caused the L to stay on dwtasheet burn out.

What do u say? You really need to use the datasheet: You can make a datashete stepper using a momentary switch, and tying the other inputs low or high, depending on the action you want e.

If you wired the LEDs with the two 0.

Probably the best approach to solving the problem would be to “divide and conquer” – break down the problem into little pieces that you can solve one at a time.

If it came from your PCs parallel port, that’s a major uh-oh. Is the L itself getting hot?
