Resolved! X-CUBE-SPN1 problem with L6474: delayed step motor action after speed change
I'm using L6474h with X-CUBE-SPN1 Version 1.10.0. I think there is a bug with the X-CUBE-SPN1 library.Step motor movement is delayed for a few seconds if the speed is adjusted more than two times (x2) of the previous speed. There is no problem if the...
Questions about motor driver drv8835
[I used a translator.]Hi,I run the motor in "drv8835 Fast DK Mode".The following waveform appears on the oscilloscope.When the pulse is low, about 6~7V is outputIs it working correctly?Is it normal not to fall to 0V?When operating in Slow DK (phase ...
What is the best way to send fairly fast sign changing angular velocity commands to the 6470H driver board?
I use the ST EVAL 6470 driver board to control a stepper motor in my tracking system! I need to send out some fairly "fast" sign changing commands! This seems to make the control board unstable! The Busy/Sync led starts flashing and starts an unwante...
Resolved! Can I use STD25N10F7 to replace STD15NF10 ?
Hello,I appears that STD25N10 is designed to a replacement for the STD15NF10. Do you confirm?Do you have any comparisons or recommendations about external gate resistors when this device is used in a three phase inverter application? NOTE: This quest...
Auxiliary winding and Self-Supply Viper16
What are the benefits of powering Viper using Auxillary winding and not self-supply?Can I power using VIPer self-supply for my Flyback converter SMPS design?How will it affect the working of the Viper?
Data Sheet Missing for STL18N65M2
The Data Sheet of STL18N65M2 is missing.On mouser.com and digikey.com I found only a preliminary data sheet without graphs.I need the graph of Rdson to check, if this MOSFET fits my application.Please update the data sheet.The link on your website is...
Does IHM08M1 can drive a BLDC motor(250W) with heavy load?
Dear All,I use a IHM08M1 with FOC control to drive a 250W motor. Motor can ramp up with light load and spin well. When the load was increasing to 90KG, motor failed to start up. After adjusting startup parameters and control mode(torque / speed), it...
How to get the energy value from STPM32
Hello,I am using STPM32 as my power sensing IC. In this I am accessing the register 54 to get the energy value. when I access the register 54 it gives me a hex value of 0x52F8FFFF. I dont know how to interpellate this to get the energy value. Please ...
L6564 used to BUCK controller, the buck output voltage is not set-point voltage at startup, and L6564 control logic is incorrect
L6564 used to BUCK controller, the buck output voltage is not set-point voltage at startup, it's output is equal to input as duty cycle =1, please help to resolve it, thanks.the below is waveform and buck circuit, CH1 is output voltage B+, CH3 is buc...
