Posted on April 10, 2012 at 02:44The new eDesignstudio does not support the VIPER53E. Original design was done by software supported by ST, but can not find it on the web. Can you send me or point me to where I can get a copy?
Posted on March 19, 2012 at 10:50Hi everybody On my simple Cw, Ccw control, for low power brushed d.c. motors, realized around L6207, i need to adjust the motor's speed. Is it a good idea to Pulse Width modulate the enable input (EA) instead using ...
Posted on March 20, 2012 at 18:09Hi! I have some questions about L6470 decoupling and voltage tolerance.1. If I use an external 3.3v to drive both Vreg and Vdd (internal reg disabled), do I still need a 40uf Vreg cap or I can use just one 10uf?2. Ca...
Posted on January 06, 2012 at 10:09Hello,I want to execute my project with HVLED805 where input voltage is 176…264 V.Output voltage for LED equal 18 V, output current 0.45 A.Edesign proposed the transformer with widings: Primary – 145 turns, Aux...
Posted on March 05, 2012 at 16:38STM3210E eval board has a stm32103ZG MCU on it and this MCU resides in XL-density group. The problem is related with ST motor control workbench. It has no option to generate header files for XL density devices unde...
Posted on February 08, 2012 at 15:30Hallo, is it possible to drive two motors with this eval board? I don't want to drive them simultaneously and independently but ''mutual exclusive'', i.e. I have one enable signal for every motor, while only one ...
Posted on February 15, 2012 at 01:24Hi, I'm working with the PMSM firmware library V3.0 to make a motor control using the STM32F103C8T6 processor operating on my own board. I am working with the provided non-RTOS project which was originally configu...

Posted on January 24, 2012 at 08:01Hi We want to overclock the L6470 (10MHz instead of 8MHz at OSCIN) to increase maximum RPM. The resolution will be reduced, this is clear, but is there any other risk to do so? Regards Michael
Posted on December 22, 2011 at 15:03HiWe have measured the output signals of the bridges in 1/128 and 1/32 step mode and we can’t see a different voltage resolution between these 2 modes (see attachment). We have used the “GoTo�-command for th...
