Winding noise during hold
Posted on October 25, 2013 at 00:06Hello, With L6472 I hear audible (high pitch) noise from motor when holding. volume of noise increase with increase hold current. It does not matter if the motor is loaded or not.When I look at winding with scope o...
Noise in a stepper motor with L6472
Posted on May 29, 2014 at 18:05Dear Enrico, I have the same problem of the other customer; I find this problem with two different family of sanyo denki's stepper motor (you can find the datasheet in the attachment): Type 103H7126-0140 and Type 103H7...
[L6470] Absolut Positioning
Posted on May 22, 2014 at 17:52Hello, I tried to poistioning my motor with the SPI command GoTo_DIR(DIR,ABS_POS). But then the motor turns a long time. So i run the command GetAbsPos, drive one step and run the command again. I wonder that one step ...
L6235 internal logic and temperature ratings
Posted on May 14, 2014 at 18:21I have 2 questions that I've posted to online support but haven't received a response. (1) I need clarification on the BRAKE input function - does it always short the 3 HS mosfets, independent of the ENA signal? I have...
L6482 Speed issue
Posted on April 11, 2014 at 14:47Hi,I'm tring to use a L6482 using only speed (Run) command because we have to use the motor in speed mode. Acc/Del are on our control. Chip Acc/Del are set to infinite (0xFFF) and MIN_SPEED/MAX_SPEED at 0,0x3FF. STEP...
L6480 high current absorbtion
Posted on May 22, 2014 at 11:42Our application:We have a Stainless steel disc diameter 30 cm, thickness 1mm, coupled with a chain to a stepper motor. The mechanical reduction is 1.5 (means that speed disc is slower than motor speed). Speed range of ...
