Posted on January 29, 2014 at 13:04Hy, i must use a full bridge driver L6297 for control two normal DC motor 24V. My uP is STM32 Cortex STM32F100 with 3,3 Volt supply. Can i control direcly the L6207 with 3,3 Volt level ?? for all the signal contr...
Posted on January 26, 2014 at 17:56 Can L6206 be used as 4 half H bridges? I want to use the L6206 to drive 4 solenoids (one end of the solenoid each solenoid will be grounded) of 2.5amps each. Can this be done without damaging the IC. ? Also ...
Posted on January 23, 2014 at 13:58Hi In PMSM FOC v3.2 which register store the speed RPM value? Thanks
Posted on January 15, 2014 at 11:41Hello.I've set up the a project with the MC lib from ST, but I run into issues with the hall sensors (I suspect). When I try to start the motor via the MC workbench, the motor makes a small hitch and then stops. Th...
Posted on December 15, 2013 at 19:47Hello,I wanted to operate a solenoid of 12V 2.5A rating. I would like to know what kind of Motor Driver IC would be suitable for it (controlling through pwm). I am confused about RMS Current and Peak Current ratin...
Posted on January 08, 2014 at 09:55Hi.I ordered the steval-ihm022v1 board. As I was familiarizing myself with the board I flashed the provided fw project (with small adaptions) and the lcd project onto the uC and it worked quite fine. But after abou...
Posted on December 06, 2013 at 08:40Hello, Maybe someone could share 'Current sensing amplification stage design tool.xlsx' mentioned in AN4076 guide or explain how to calculate initial values of current sensing amplification filter? Or maybe there ...
Posted on December 17, 2013 at 18:01Hi, using the L6480 motor driver, having a problem with noise, probably due to the starting pulses of the sine wave. Its at 1/128step mode. Attached is a picture of the problem. Anyone know what settings need to ...
Posted on December 20, 2013 at 11:39Hi,Are the M05 to M07 series of VIPower IC suitable for PWM control of resistive and inductive loads? The app note from M03 (AN1596) specified, ''In fact a standard number of cycles of a HSD is over 500,000 and th...
Posted on December 16, 2013 at 09:50I use ST L6470 with unipolar motor. L6470 is biplar type dirver, so I unconnected com line of unipolar motor. motor spec is below: MAKER: sanyo denki type : 103H5210-0480 1.2A/1.8DEGREE/3.3OHM. because unconnec...
