The other end of the potentiometer goes to GND.

L – Stepper Motor Controller – STMicroelectronics

Support Home Video Center. U were right ; the first one’s pin 4 burned so i changed it with a new one. Sync and home also to nothing. The draws typically 50mA could be as much as 80mA from the supply. Please read the fine datasheet RTFD and learn what the outputs are used for. At last Today i bought 10 leds to understand how L works. The L can be used with monolithic bridge drives such as the LN or L, or with discrete transistors and darlingtons.

Who We Are Management. Changing the control mode will often eliminate this. Quick Links Categories Recent Datashet.

Don’t Have an Account? First i put them between every pin and ground ; but only 2 of them workedalso i changed the CW to high but the same and when i send pulses to clock they went off.

Selectors Simulators and Models.

L297 Stepper Motor Driver IC

As my schematic shows: No availability reported, please contact our Sales office. It’s a ready-to-use touch sensor switch compatible with the Grove system.

My problem is that I don’t really know what the Vref, control, sync and home pins do in this cirucit and what they connect to Menu Products Explore our product portfolio. Sign up using Email and Password. First i want to check L all alone.

The answer is “yes” to your question regarding the other pins. If you’re using a 5V supply datasheett will get warm.

L297 & L298n

L datasheet My problem is that I don’t really know what the Vref, control, sync and home pins do in this cirucit and what they connect to Dattasheet puts a little flag by your title so people know you are asking for help. Also, I think it’s best to make your title say something like “I need help with Pulse Now the thing is ; when we say pulse i thought it was “0 to “5 but is it opposite?

What do u say? Also from the L datasheet: You can use the schematic I provided for an adjustable output. If an external clock source is used it is injected at this terminal.

Did i wire it ok? The fixed resistor limits the maximum current that can be set to avoid burning out the driver transistors:. 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.

Anything smaller allows more current and risks burning dagasheet the L Do you have a link to the type of motor and motor specs? This item was manufactured prior to August 31, Control input that defines action of chopper.

Product is under characterization. A little 8 pin DIP that can be hacked into a light or line following robot known as the “Herbie”.

Simple, logic-controlled variable speed fan for fire-fighterbots and other wind-inducing experimentation beans not required. Personally, I have no idea how to control parallel ports on computers, but I’m sure somebody here knows how to do that.

So I am having trouble with a circuit I am building for a stepper motor controller, I am currently following this schematic My problem is that I don’t really know what the Vref, control, sync and home pins do in this cirucit and what they connect to, and because of this I haven’t connected anything to them when testing my circuit. dataheet

Page 8 of the datasheet shows how this is used.
