Hello, we're using the EVSPIN32G4 ST evaluation board. in this evaluation Board design with two microcontrollers (stm32f103cbt6 for debugging and STSPIN32G4 for motor control). Unfortunately, the STM32f103cbt6 microcontroller has failed!! We bought...
I have a PowerSTEP01 that is behaving unexpectedly when I send the ResetDevice command.If I send it when my system starts then everything is ok when I check the STATUS register.However, if I send ResetDevice after the motor has been moved (sequence e...
Hello,I have a problem to configure the powerstep01. The motor current drops at medium speeds.Current modestep clock mode1/16 microstep48 VoltI have set a low acceleration for testing. Everything is fine up to approx. 16 kHz (microstep). That's only ...
When using the external step input of the Powerstep01, will the internal logic also use the advanced fast decay mode and switch between micro and fullsteps if a given speed limit is reached?Or does the step input only count microsteps and not using a...
In the STPSIN software, it seems that I am limited to 15609.741 Steps / sec?(See picture below)With a 0.9 degree motor (400 steps / revolution)this limits me to15609 steps/sec * 1 rev/400 steps * 60 sec/1 minute = 2341 RPMIs this the maximum speed o...
Hello,just a short question: In Sensorless Mode the startup sequence works with "Align Step", where the Rotor starts from a fixed position. There is a define for the Motor Startup Angle (STARTING_ANGLE_DEG)... Is it relevant if there is 90 ° or 0 ° e...
Posted on October 25, 2016 at 20:05Hi All,I want to make a BLDC motor driver board using L6235N DIP.I wired all the components on the breadboard as per schematic diagram and component list is given in ST Application Note AN1625 page no. 35-37.I am u...
Hello,I am trying to develop my own sensorless motor control using the STEVAL-ESC001V1 Board. The motor used is a 6 poles BLDC motor. I have successfully been able to run the motor in open loop and it’s running well.In order to have feedback and esti...
Hi, I am a bit confused about PWM motor driving. Is Vref the same value as Vavg of PWM? I tried to calculate the value of PWM current control but there have the result is not the same current value as I measured from a test, here are the parameters;R...
