L6235 current control
Posted on July 08, 2016 at 15:40Hi i have a problem regarding the L6235PD. With the EVAL6235N everything works fine. Problem is my own PCB layout. The monostable never triggers the bridge off and the motor consumes a lot of current compared to the e...
L6470 When CS goes low pulls SDI down with it?
Posted on July 05, 2016 at 11:11Hi,I have been using an microchip explorer16 board with the EVAL6470H board and working fine. Swapped over to my design PCB and there is a peculiar fault where when the CS pin is high the SDI at the L6470 works normal...
EVAL6470PD Vdd supply and SW input
Posted on June 30, 2016 at 22:42I have two EVAL6470PD boards that I will be using to drive the stepper motors in an XY stage. They will be controlled from a PIC32 board through SPI. Is there any performance or noise immunity advantage to using an e...
What kind of impact can demage the L6470pd in that way?
Posted on June 27, 2016 at 13:35Hi at all, is there someone with an idea what has happened there with the L6470. I´ve attached 2 photos of the demaged device and on picture of the scematic sheet. It looks like the motor bridges are directly shorted ...
[STM32F10x] Timer 1 overflow/underflow not correctly
Posted on June 26, 2016 at 07:06Hi everyone,I'm building a BLDC motor control project which use 6 steps for control. And now, i wanna sample ADC on timer1 overflow when PWM-ON (PWM run in PWM mode 1 and Center-Aligned3). I get an issue: Timer 1 over...
L6480 SPI errors versus gate drive configuration
Posted on June 20, 2016 at 08:23Hi, I designed a board equipped with two L6480 motor drivers; the drivers are connected in daisy chain mode. To keep the two motor synchronised, the OSCout of the first driver of the chain feeds the OSCin of the secon...
evalL6474PD not working
Posted on June 17, 2016 at 22:37 i bought two different ST motor eval boards connected to the STEVAL-PCC009V2; eval6470PD and eval6474PD. the eval6470PD works fine but i want to use the eval6474PD for technical reasons ( current vs volt control). th...
Sensorless IPMSM (HFI): Problems with North-South Identification and motor turning in wrong direction
Posted on June 16, 2016 at 18:11After having solved the main issue with my PCB some weeks ago, I'll open a new thread so as to avoid making a mess now things are different. I'm still working on a sensorless (HFI) IPMSM which should run between 0-90R...
L6491 Dev Board Control
Posted on June 15, 2016 at 17:24Hello again,As an update I got my Development Board working blinking a light. I noticed that increasing the pulse frequency in HIN/LIN causes the Gate pulse width to change. The input is symmetrical to the output unti...
STBCFG01 and the eval board software
Posted on June 14, 2016 at 22:06Where can I download the eval software for the STBCFG01 eval board? It seams to be hidden very very well. It's why I bought this board... Thanks, Kevin
