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...

Slow Speed Motor Control
Posted on October 27, 2015 at 21:37I am having troubles controlling the speed of my motor below ~100 RPM (~10Hz on the halls). I am having similar issues with both Hall Effect and sensor-less modes. I could understand this being an issue with the se...
how to start using PMSM to write FOC ?
Posted on October 21, 2015 at 07:32I downloaded the PMSM Motor Example. I want to fix my own programs, but has no idea .I just wanted to ask if the external input from ia, ib, via FOC algorithm, the output value of the three-phase voltage to the osc...
Brake for on-the-fly start-up
Posted on October 28, 2015 at 19:46Hi, According to the user manual UM1080 p.16, ''The duration of the ''braking phase'' that is applied if the sensorless measurements doesn't give reliable measurement during the ''detection phase''. During the ''br...
Non-detected Stall L6474
Posted on October 20, 2015 at 14:44I am working a bipolar stepper motor against a spring to assess the torque delivered. The test drives a set distance and then returns. Software produces a constant accel profile in incremental steps of pulse rate....
L6566BTR - Standby mode Power
Posted on October 16, 2015 at 04:29Dear Sir/Mdm,Currently i had one project using the STM Power IC (MPN: L6566BTR). I wanted to know what is the standby mode power can be reach for this IC. Can it go down to 0.5W on the standby mode without any load...
