Posted on October 21, 2014 at 00:52In the datasheet for the L6229Q, section 5.2 states ''Pin EN (Enable) has identical input structure with the exception that the drain of the overcurrent and thermal protection MOSFET is also connected to this pin.'...
Posted on October 17, 2014 at 05:56 Hello, I see this question in the forum, but no one reply. Can anyone help to feedback how to solve this problem? Because I encountered this issue too. Thanks. ===========================================...
Posted on October 24, 2014 at 14:53Hi, I am not entierly sure how to correctly enter my motor parameters, and which effect they have, can anyone check if I am doing this correctly (sensorless operation with cordic startup, no extra features like flu...
Posted on October 24, 2014 at 15:01Hi Gigi, I currently browsing the library source code to see how I can integrate this start-up behavior: 1) start FOC algorithm using rough angle given by hall sensors 2) wait for I channel of quadrature encoder to...
Posted on October 26, 2014 at 05:55I need a Full Bridge driver IC capable of at least 2.5 Amps at 125 kHz.The L6225 connected in parallel looks good but the highest frequency is only rated to 100 kHzIs there a higher frequency version of this or can...
Posted on October 21, 2014 at 02:19Gigi: I have a question, measured in workbench Motor Electrical parameters Rs and Ls. I see ST data is used RLC meter measurement frequency at 100 Hz, but the motor is running in the PWM 16K frequency, wheth...
Posted on September 05, 2014 at 03:36I'm finding that the L6474 runs terribly hot even at 1.4 amps . Its on a decent PCB with 20 plates thru tholes a small heatsink (1'' x 1'') on the back and it will rise to 110 C in less than 2 minutes . It is the...
Posted on October 02, 2014 at 22:29I am attempting to run the L6470H discovery kit with the dspin software from a machine with windows xp on it. I was previously able to run it from another machine with xp, I installed the same files but cannot conn...
Posted on September 18, 2014 at 21:39Dear Motor IC Forum: I am using an L6470 to drive a stepper motor attached to a gearbox and am not able to achieve step rates greater than roughly 700 steps/sec with any microstepping setting. The motor gets loud...
Posted on September 26, 2014 at 04:52 This routine to be performed inside the end of conversion ISR,from the function ,we can see that the ext. adc triggeringis disable when the motor state is RUN.So,how can we to trigrer AD conversion for the nex...
