You really need to use the datasheet: Ruby, you might also get more attention if you go 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.
The fixed resistor I chose will limit the max adjustable phase current to 2A.
Vref is set by a voltage divider to a voltage equal to the peak current multiplied by the value of the current sense resistor s. Then i put pair for each output ; one pair between 4 and 6 numbered pin but opposite directions ; datasyeet same Quick Links Categories Recent Discussions.
Can someone please tell me what did i do wrong?

L – Stepper Motor Controller – STMicroelectronics
I have problem with wiring L – Ln. Sign up using Facebook.
If it came from your PCs parallel port, that’s a major uh-oh. If you can’t find 40k Ohm, use the next larger value or a combination of 2 resistors. Also consider accepting an answer to any of your questions that solves your problem. So I am having trouble with a circuit I am building for a stepper motor controller, I am currently following this schematic. Page 8 of the datasheet shows how this is used.
The wiper of the potentiometer goes to the Vref pin. A feature of this device is that it requires only clock, direction and mode input signals.
Product is in volume production. If you are building a single motor driver on your board, you can leave this pin disconnected. Since the phase are generated internally the burden on the microprocessor, and the programmer, is greatly reduced.
I am gonna give vatasheet try again but what do u think about the post that i wrote ; the one with the pictures? The other end of the potentiometer goes to GND. Sign In or Register to comment.
arduino – Trouble with L pins – Electrical Engineering Stack Exchange
Spehro Pefhany k 4 Changing the control mode will often eliminate this. Also, I think it’s best to make datashset title say something like “I need help with I did everything as in datasheet but i didn’t get anything but a burning smell. Thank u so much The fixed resistor limits the maximum current that can be set to avoid burning out the driver datashert.
Grove-compatible circular 24 LED array, ideally used with a rotary encoder input. I have 4 wired stepper motor and how can i connect them to Ln? At last Today i bought 10 leds to understand how L works.
L297 Stepper Motor Driver IC
Sync and home also to nothing. I check the the motor and it needs 6. Sign up or log in Sign up using Google. I mean is it has to be connected to 5 volts than suddenly cutting it off? As you can see on the k297 on page 2 of the L datasheet, this is the reference voltage which goes to internal comparators and is compared daasheet the voltages coming from the current-sense resistors.
ST Code of Conduct Blog. No availability reported, please contact our Sales office.
One end of the potentiometer goes to the 40k Ohm resistor I recommend the CW pin of the potentiometer.
But first, perhaps if you could provide a photo of your wiring set-up, then that might help datazheet things started. A failure of the L often results in a failure of the L and could be why it is getting hot. Output of the on-chip chopper oscillator. You can leave this pin disconnected. I will need to change my software but at least now the first part l2977 working and more important i understood how it works Reference voltage for chopper circuit.
