Posted on April 15, 2013 at 14:25According to Datasheet Reference:In order to convert the SPEED value in step/s, the following formula can be used:[step/s] = (SPEED X 2 –28)/ tickThat would mean that if I would like to work with step/seconds I hav...
Posted on July 09, 2016 at 13:00Does anybody have an idea, is STPS20H100CT on the photo genuine, or just another one China fake?It is suspicious that it is marked with an unusual for ST font and a circle around ''e3'' is rather an ellipse, but the o...
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...
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...
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...
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 ...
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...
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...
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...
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...
