L6470 BEMF calculations
Posted on February 12, 2014 at 00:59Hi,Is there an online version of the BEMF compensation tool? I have a couple of boards from Sprakfun that are based on the L6470 but I'm having issues getting the performance out of the stepper motors that I thou...
L6470 motor power interlock
Posted on February 11, 2014 at 20:11I am using an L6470 controller in an application that requires an interlock circuit to stop motor rotation if the interlock switch opens. Is it possible to safely switch 24V power to the VSA and VSB pins off then ...
L6206Q jitter
Posted on February 07, 2014 at 09:56Hi, we are evaluating the L6206Q using the EVAL6206Q board. The output of the chip exhibits excessive jitter. Is this a regular behavior?more desc.: supply voltage 15V, test load 15R/5W, input signals 3V3, 50kHz, ...
L293 shorting output problem
Posted on January 23, 2014 at 10:12I use L293 as an buffer and level shifter from 5VDC to 24VDC on two of our boards and it works perfectly except for one thing: shorting any of the outputs to GND kills the chip! Could you suggest me a solution to t...
Vnh5019 arduino shield
Posted on February 04, 2014 at 23:40 Hi guys, i saw ST made available EVAL-VNH5019-P2 an arduino motor shield with VNH5019 H bridge. where i can get this board? i don't find it in ST e-store. #vnh5019
L6207 signal and control With 3V3 ucontroller
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...
L6470 step mode step pulse width
Posted on January 28, 2014 at 16:39What is the minimum step pulse width? What are the setup and hold requirements for the direction pin with respect to the step input? I could not find this in the datasheet. All I could find is that the max rate is...
Can L6206 Dual H Bridge used as 4 Half bridge outputs?
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 ...
STM32 FOC V3.2, how do i get the speed (RPM) info?
Posted on January 23, 2014 at 13:58Hi In PMSM FOC v3.2 which register store the speed RPM value? Thanks
speed feedback fault
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...
