GoTo(ABS_POS) error during motor running
Posted on September 03, 2014 at 09:59Hello!In my application I send GoTo(ABS_POS) commands when stepper motor is running at constant speed, when BUSY flag is high, so I'm sure that the target speed is reached. And everything is going well most of ti...
a formula about duty cycle computation
Posted on August 03, 2014 at 06:34hello all : I,recently?found that the formula about duty cycle computation in the SW do not accord with that in the user manual . Sector ????TimePhA=T/8+?T+X-Z?/2 in the SW,however,Sector ????TimePhA=?T...
Input Voltage limit on VNH5050 Diag/ENA pin
Posted on August 14, 2014 at 03:20HiI'm designing a very compact quad VNH5050 12V Motor Driver board.I can optimize my design if I can pull-up the DIAG/ENA pins to 12V rather than the 5V Logic level.There is nothing else connected to these pins. Al...
Problem about L6482H (OCD failure)
Posted on August 22, 2014 at 19:45HiI have developed about motor control by using L6482H. I follow circuit form reference circuit of L6482H Eval board (same part). Now I stuck at OCD failure. I have construct a new board follow Eval board. In Eval b...
DMOS Driver L6208 For bipolar stepper motor Heating issue..
Posted on August 11, 2014 at 12:34hi,I am trying to drive bipolar stepper motor having 2.8A/phase current requirement using EVAL6208PD , after exceeding current limit of 1.5A drive IC get heated. Is it possible to drive bipolar stepper motor having ...
L6207 PWM Current Control Question
Posted on July 30, 2014 at 19:04Could someone please explain how current is controlled on the L6207 via onboard PWM Current Controller? Additionally, AN1762 APPLICATION NOTE indicated a constant current could be obtained through a simple voltage di...
L6470 Stall detect issue
Posted on July 24, 2014 at 15:26Hello, I am posting this question that another user posted but there was no answer. Can anyone help?Can't reliably sense stalling using L6470 chipI've been quite successful at controlling the L6470 stepper driver chip...
Problem for EVAL6482H
