Posted on November 02, 2013 at 09:31hi,guys, how to calc ''Running target current''?? stepper motor parameter:1.5A current?nameplate?this is RMS current??????? min speed:50 steps/s,max speed 2000 steps/s, ACC 1000 steps/s2, test board:EVAL6470H &&...
Posted on December 03, 2013 at 13:32Hi please help me to design 3 watt LED driver using viper22AE. The information given in datasheet is not getting me.
Posted on November 21, 2013 at 18:17Also with the EVAL6480H, I have 2 boards in an SPI chain. After configuration, I can only make the first selected board work. To make the other motor work, I need to shut the power off, start over, and select the ...
Posted on November 14, 2013 at 18:33Would anyone have the schematic source for the Viper53 board STEVAL-ISA013V1 ? (Any format - Orcad, PADS, Eagle, etc ...)
Posted on October 15, 2013 at 13:48Hy, i must build a new board for control Stepper Motor. The pwm control logic and all, is manage with new cortex STM like STM32F100RBT6B. I want an unique 3V3 logic supply for all, is possible drive and receive al...
Posted on October 02, 2013 at 17:40Hello I understand: 6470 uses voltage mode drive/bemf compensation 6472 uses current mode drive/adaptive decay comp compensation If my uStep requirements are 1/16. What other parameters should I consider for my de...
Posted on October 20, 2013 at 01:31Hello I would like to ask to the experts a question regarding BLDC motor control. I am currently trying to develop a Brushless motor controller that allows me to control the torque and speed of the motor. The motor...
Posted on October 13, 2013 at 13:34Hello, I am not sure if this is the right forum to post in. My question is about the L4891 PFC controller, Is there any calculator for extracting the inductor value, and all other values? Its going to be a very com...
Posted on October 12, 2013 at 12:38Hello,I design the automation system with using l297 and l298 chips. Where can I find safety parameters of this chips (MTBF, MTTF, SIL or FIT) ?Thank for answers. #l297 #sil #mttf #mtbf #l298
Posted on April 18, 2013 at 16:45HI , 1.can any one tell me how to PWM DC motor using L6205 ,via EN pin or INX pin ? 2.how can i make the motor coasting (in PWM OFF) ? for the Table in the Datasheet when EN=1, if IN1=0,IN2=1 => OUT1=GND...
