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...
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 .
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...
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...
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.
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...
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...
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...
Posted on May 26, 2015 at 13:40When the SW input to the L6470 chip is pulled LOW (by a switch closure or a LOW output from a logic circuit), is the ReleaseSW command the only way to move the motor? Are all of the other constant speed commands, abso...
Posted on May 28, 2015 at 14:12 Greetings, We are using this component in a board with a STM32F103CB with FOC firmware 4.0, the parameters code are generated via most recent Motor Control Workbench. The 6 PWM signals are well generated, and the L623...
