Posted on July 22, 2016 at 10:42Could anyone explain how the start up circuit works in the schematic available in the given application note ?Is it possible to simulate that schematic in e design suite ?
Posted on July 15, 2016 at 17:29 hi all, i need design software or excel sheet for Viper22A kindly send to secure_tech2000@yahoo.com. Thanks. sudhir kumar
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...
