L6470 & Maximum currect limiting
Posted on February 28, 2013 at 11:20Hi, I'm evaluating the L6470 for a project. Going over the datasheet I noticed that the minimum value for 'maximum current limiting' is 375mA. I need to drive a very small stepper (6mm) with 12V power source. Acco...
Frequency pwm with stm3210b
Posted on December 05, 2012 at 10:23Hello, I'm working with stm3210b-eval, I'm doing the following procedures : 1 : I generate with st Workench files in systems drives and params 2 : I compile with IAR But, in ST workench, the frequency params is 16...
PID controller
Posted on January 30, 2013 at 19:06I want to use the pid function in the library arm math. if I project the PID controller in the domain S as I can find the constants KI, KP, and KD in the discrete-time to give the PID controller?thanks for your he...
STM32F4
Posted on January 08, 2013 at 15:24Hi, I am using the STM3240G card with STM32F4 microcontrolleur. I would generate PWM for motor control. However, I need to handle data coming from a primary card ( beagle board) by ethernet (RJ45) with udp protocol...
IFN003V1, MC Library v3.0, 3.2, IFN003V1 Patch
Posted on January 11, 2013 at 18:38I'm attempting to get started with an IFN003V1 board.I am new to STMicro software tools and eval boards.I could not find V3.0 of the MC Library, so I installed V3.2. I didn't find an IFN003V1 project, so I attempt...
L6470 problem: continuously read out status register
Posted on December 21, 2012 at 16:16Hi, I�m playing around with the L6470 which finally worked quite well. But now I�m experiencing the following issue: I want to continuously monitor the status register of the L6470. But when I send a �run� command...
L6470 vibration
Posted on November 16, 2012 at 22:38Hello! My question is in follows:I got L6470 working, but not in a desirable way. Stepper motor vibrates in all speed range. It seems that phase current form distorted as shown in Fig. 15 (Section 7.3, p. 35 of da...
Encoder interface
Posted on November 21, 2012 at 17:51Hi everybody!I have a problem when i reading data from ENCODER to stm32f103rc. My code is in the following:/* */#include ''stm32f10x.h''#include <stdio.h>#include ''main.h''#include ''stm32f10x_it.h''#include...
L6470 step loss
Posted on October 03, 2012 at 17:36In a L6470 the microcontroller sends a Move command in 128-microstepping type; then, after a zero is read in the busy flag (so the movement has finished), the absolute position is read but the value read is smalles...
L6470: Several problems evaluating a Stepper-Motor Application
Posted on November 09, 2012 at 03:39Hello,We are currently evaluating the L6470 to drive analytic high-pressure pumps for Mass spectrometry.The final goal is to drive a stepper-motor in high precision micro-stepping mode at around 1.7 Nm at a maximu...
