POWERSTEP01
I am developing a control system, for an industrial doser, for this I use a stepper motor, of 5.6amp, 0.5 ohm, 3.6mh and a KE .233.I have all the system implemented, hardware and software.To tune the engine I used the EVLPOWERSTEP01 development tools...
How to reduce the zero current offset reading from one of the channel of STPM33?
Hi, I am using STPM33 for energy monitering. I have 2 STPM33 in my design and hence there are 4 current sense channels where I use shunt resistors for sensing. The problem faced by me is that the fourth channel is showing an offset of 6 mA when zero ...

I would like to know the following specification of STWLC03.I tried to find the STWLC03 datasheet, but I could not find it on your wave site.Would you please let me know them. ・Input AC voltage Maximum rating ・Output voltage Maximum rating ・Digita...
How do I get my motor to spin?
I have a BLDC 4 poles motor with a rated voltage and current of 36V and 7A. I followed the instructions on the get started pdf for the STEVAL-SPIN3201 board, tried to change de start-up parameters and I can't get my motor to spin.
L6235 Motor jumps to Max above certain reference voltage
Posted on August 01, 2016 at 10:17Right now I am working with the evaluation board EVAL6235N and I adapted the L6235PD to it and changed the Shunts to 0,167 Ohms. The motor is a fan from Micronel which has a maximum average current of 1,5A when free...
CURRENT MEASUREMENT BY 2 SHUNT RESISTORS
Hi All,Having some doubts regarding the current sense.When using dual shunt current sensing technique, we have 2 current sense resistor at the Phase A and Phase B inverter legs.The 3rd phase current can be calculated in code.But ,my concern is regard...

Problem with 2 bits ABS_POS
Hi,I'm using two L6472 with kinetis processor.Everything seems to be ok, except for ABS_POS ( absolute position register). When i read value with getparam(abs_pos) 2 bits stay all times at 0 and obviously data are corrupt.In first time, I think It's ...
HVLED001A - Over voltage ishue
Designing an 80W power supply based on HVLED001A for 40V out at 2Amp. The issue is at lower loads it shots up to 60V. loads greater than 1 Amp it drops down to 40V. the layout is based on the edesign suite by ST., in addition, the Cclp, RCLP, HVLED00...
