L6205 , PWM
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...
L6470, move and speed change
Posted on October 08, 2013 at 11:09Hi. Using L6470 I need to move to absolute position with the possibility to change speed during motion. I need the Soft Stop (or something similar) when reaching the target. Speed change during motion is possible ...
L6480: High side MOSFET of both h bridges not turning ON
Posted on October 01, 2013 at 05:34Hello, I am using L6480 stepper motor driver. I have connected my board with SPIN software. If I run the motor status is shown as motor is operated. But in this case High side MOSFET's (HVGA1 & HVGB1) does not turn...
Eval6470H R1.1 && (Arduino || Steval-PCC09V2)
Posted on October 04, 2013 at 15:16Hi. I played with the eval board+steval to set my step motor parameters. It works flawlessly. Now I'm writing Arduino code to get the same control. Motor parameters have been copied by the Register Map. SPI routine...
