L298n - Dual Brindge Driver - multiwatt 15: Why Sense a and Sense B ?
Posted on December 16, 2015 at 04:14what purpose having Current Sense A and Current Sense B pins in L298 ? does it mean we can monitor the current of the motor using shunt resistor ?Thank you for your answers. #dc-motor-control #bldc-motor-contro...
L6470 limit switch problem
Posted on December 03, 2015 at 19:57Ive using 4 L6470 in a 3D printer application. The limit switch inputs are acting erratically. Sometime they work, when switch goes low driver stops, and I can see the switch input on the status. But then other ti...
Trying to build example project for X-NUCLEO-IHM07M1
Posted on November 17, 2015 at 02:16Hello, I'm having trouble building any of the example projects in the SPN7 package. I'm using AC6 tools on the Nucleo-030 board. The projects can be imported but won't build due to many many wrong paths for incl...
L6482 tick period
Posted on October 23, 2015 at 01:53Many of the equations for the motion controller within the L6482 use 250 ns as their time reference (tick). Does this value scale with clock frequency or is it divided by the appropriate values to always generate a...
Errors in L6207 and L6208 datasheets and application notes
Posted on November 11, 2015 at 13:59I've found some errors in the data sheets for the L6207 and L6208 motor drivers and also in the L6208 application notes.How do I report these errors
IHM01A1 L6474 reset pin during active output
Posted on October 13, 2015 at 11:11 I have some question regarding the board (maybe anyone of you have a better understanding on electronic). I use the board with stepper motor to moves a cart on the linear drives. The move will be limited by proxim...
How does PWM timing work in L6470
Posted on September 03, 2015 at 13:50My question is a typical 1.8deg step motor (200 steps per rev) set for 128 micro steps will finish each micro step in <10usec at a speed of 300RPM. With a PWM period of 64us (15.625K) how this PWM can set a desir...
L6470: Switching between two speeds using Run command causes current to slowly drop
Posted on September 01, 2015 at 09:43Hello,I'm using an L6470 over SPI to change between two speeds every few seconds (say 1000 steps/s <-> 1100 steps/s). To achieve this I am issuing the Run command alternating between my two set points.I have noti...
Viper06: documents for the compensation network design
Posted on November 14, 2012 at 15:15Hi, I'm just searching for some Viper06 documentation like some application note that explain-me how to design the compensation network. I just get some value with the online tool, but I'd like to understyand how ...
Viper06 over current
Posted on November 12, 2015 at 12:51Hello, I've done a Viper06LS based AC/DC converter. The criteria : full bridge ahead, 26V, 0.11 A out. I've designed it with the online tool, but the circuit is always in overcurrent (on 250ms then off 1s). Is t...
