L6474 -- much faster in forward direction than in reverse?
Posted on June 22, 2015 at 16:05I've been encountering a strange problem. I can use the L6474 to move a stepper motor pretty fast in the forward direction. When I flip the direction bit though, I find that I can't make it move anywhere near as fas...
Non-detected Stall L6482
Posted on June 30, 2015 at 15:58Running a bidirectional stepper at 30V with L6482 and getting actual stalls in 16-microstep mode -- under load the motor literally stops and hums, but nothing is reported back to software. It's like the driver has not...
stm32
Posted on June 10, 2015 at 10:16Can i interface a quadrature encoder to stm32 without using the channel 1,for example using the channel 2 and channel 3 .
L6470 in HiZ state chip gets hot is it normal?
Posted on June 14, 2015 at 20:55Hello I am new to dSpin, but straight to the question.I have a L6470h setup on a protoboard using schematics found in the usermanual.But I see that the chip gets very hot even though it is in HiZ state. I measured the...
TBOOST Usage L6482
Posted on June 30, 2015 at 16:04The manual describes the function of TBOOST well, but none of the examples of configurations that I have seen show the parameter set to anything besides 0x00, or really when it would be useful to implement it. Could s...
Power supply requirement for EVALSTGAP1S
Posted on June 09, 2015 at 19:01Hello,I just wanted to know the required current capacity for VH and VL for EVALSTGAP1S. I am using it fior SiC , VH=20V and VL = -5V.

Speed Control according to DT0001
Posted on March 11, 2015 at 10:54Hi, the application note DT0001 suggests controlling the motor speed by using the FWD/REV pin with a duty cycle. Though this sounds very promising especially for feed-back controller design I was wondering what happe...
stepper motor
Posted on May 18, 2015 at 06:33HiI want to select a stepper motor for my project. I use L6470 IC drive.I�m new in motor working. I need a bipolar 2 phase stepper motor with minimum voltage 8 volt. Is it correct? Could you guide me in choosing a corr...
PowerStep01 Register Address and SYNC signal
Posted on June 05, 2015 at 16:53Hi, We have a couple boards with Powerstep01 engineering preview ICs. We can get the motor up and spinning, but we ran into a few issues. First, the register address for CONFIG and STATUS do not match the curren...
