Problems in Configuration of my L6482 board
Posted on March 23, 2014 at 11:37I have designed a board using a L6482 chip. My L6482 has started, and I can send and receive messages a través de SPI bus, but now I have a problem: My STATUS register says: 1110 0000 0000 0011 (Get Status Command =...
Motor Controller for BLDC Motor
Posted on June 26, 2014 at 12:43Hi, For our Medical Respirator equipment, We need Micro controller, Which is capable of controlling BLDC motor up to 60,000 RPM with minimum CPU utilization. Please suggest suitable microcontroller from ST. Thanks ...

L6470
Posted on June 03, 2012 at 21:47hi , i am currently evaluate l6470 and have a few questions : 1. does the driver suitable for stepper motor with max 3A current per phase ? 2. how to obtain maximum holding torque ? ( setting K_HOLD to FFh ?) #go_u...
L6470 Power ON and RESET
Posted on June 20, 2014 at 07:29HiI'm using L6470.It works to move step motor a bit,when the Powered on.The motor's coil Voltage was high between the RESET turn high and First SPI communication is started.(Almost 10ms?CPU's order)I don't want to m...
Step-Clock Mode
Posted on June 17, 2014 at 11:15Dear all,I actually using two l6470 boards (to control two stepper motors), connected in daisy chain configuration also with STM32F4DIS-EXT.I don't understand very well how to control these drivers in STEP-CLOCK mode....
Control 2 motors (X and Y) with l6470 in daisy chain configuration
Posted on June 11, 2014 at 10:51Dear all,my question is about how to realize a syncronous movement of 2 stepper motor (one move in X direction and one move in Y direction), controlling by 2 l6470 connected in a daisy chain configuration also with ST...
in-rush current control
Posted on June 03, 2014 at 01:40I am working on a large system that is comprised of several different subsystems supplied with AC mains. In order to control inrush current to the system I want to build a controller that switches on AC duplex outlets...
Winding noise during hold
Posted on October 25, 2013 at 00:06Hello, With L6472 I hear audible (high pitch) noise from motor when holding. volume of noise increase with increase hold current. It does not matter if the motor is loaded or not.When I look at winding with scope o...
Noise in a stepper motor with L6472
Posted on May 29, 2014 at 18:05Dear Enrico, I have the same problem of the other customer; I find this problem with two different family of sanyo denki's stepper motor (you can find the datasheet in the attachment): Type 103H7126-0140 and Type 103H7...
