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...
Posted on March 12, 2014 at 17:43A new application is producing problems with very high spike currents. We are driving 4 STGP20H60DF using two L6390 in two half bridge setups, for a specialty single phase motor (not a standard motor, I can't t...
Posted on February 05, 2014 at 09:13hi, do st offer some software application example for this EVAL-VNH5019-P2 pololu arduino shield? i have two high current application where would fit. one to drive a high current stepper motor. the second for a du...
