Posted on April 11, 2014 at 20:13I am quite novice when it comes to stepper motors and am having some difficulties. I am evaluating the L6470 to replace an old step/dir motor drive. The motor used is an Applied Motion HT17-075 nema17. Form the specs...
Posted on March 19, 2014 at 17:24We are working with the STEVAL-IHM023V2 to drive a brushless DC motor of 24V. The set up is to be used in an academic environment and will be used as set up for students. As it is their task to make the control algor...
Posted on March 28, 2014 at 11:35Hi I am running the Motor Control library 3.4.1 on the STM32F107xC. It keeps crashing into the 'Hardware Fault' exception. I have made the necessary adjustments to the IAR project build, and had to adjust some define...
Posted on March 11, 2014 at 06:45Hi We are using uC/OS II RTOS. How do I modify the MC Application project to call the relevant BSP_IntVectSet() (handler setup)? Where is the best place to do this? (I am taking care not to double-up any application...
Posted on March 24, 2014 at 02:53Hi The MC Toolbox wizard (and presumeably the MC library itself) seems to support only the use of p-n junction temperature feedback devices (25mV/degC), with support to alter coefficients. In our application we are u...
Posted on March 18, 2014 at 13:47Hi, I am trying to use the PCC009V2 and an EVAL6470H board through the spinFamily Evaluation Software. but i get the following error: I have connected the SPI_IN cable to J1 on the PCC009V2 board. A motor is connecte...
Posted on February 27, 2014 at 13:12I mad some tests with L6470H in microstepping mode and it seems that microstep positioning is not possible with this device. In my test a microcontroller will send a hard stop command to the motorcontroller when a...
Posted on March 18, 2014 at 13:33Hi,I am making SMPS as in title based on VIPER17HN. My concern is if the voltage on both sides of optocoupler should be equal. On diode side i have nice stable 3V, while on second side (the one by FBpin) there is 0,5...
Posted on March 05, 2014 at 11:21Hi, Description of this Register is confusing me all the way. It is written: ''When the LSPD_OPT bit is set high, the low speed optimization feature is enabled and the MIN_SPEED value indicates the speed threshold b...
Posted on February 21, 2014 at 11:38Our Setup:L6470 with a small stepper (75mA Phase Current) and a linear stage. We need to extend the movement Interface of the IC of +-2^21, to do long movements but have smoother movement in microstep mode.Therefo...
