STM32 SVPWM modulator
Posted on July 20, 2014 at 15:17Hello, I am looking for solution of SVPWM implementation for STM32F103 microcontroller. My application is AC motor frequency converter with U/F = const regulation. Best regards Andrzej #stm32 #3phase-motor #frequen...
FOC Control and Resolver input
Posted on July 29, 2014 at 18:04Hi, I have a PMSM which I'm planning to run sensor-less. In case I run into problems with the sensor-less the motor I'm using also has a resolver fitted. I have a Resolver Decoder from analog devices so I'm wondering...
L6470 step loss A (or B)
Posted on July 21, 2014 at 23:12i've been using the L6470 driver successfully but have noticed that i get step loss on the a and b bridge. the data sheet indicates that when this happens the appropriate bits in the status register get set. unfortuna...
Driving a proportialnal hydraulic valve with VN5E050?
Posted on August 06, 2014 at 11:43Hello I would like to control a hydraulic valve (24V, 0-2.6A) proportional (0-100%) with a PWM signal from a MCU. I need to measure the current, detect open loop and short detection to VCC. I found the VN5E050J-E,...
L9958 SPI control
Posted on July 22, 2013 at 15:39The question is related with the command word under the SPI protocol title. In this protocol uC should sent the command word to start protocol but I can not find the structure of this word. In datasheet the CFG_REG an...
L9942 - Motor lose some microsteps
Posted on August 08, 2013 at 20:17I want to control a stepper motor (http://pt.farnell.com/astrosyn/163/stepper-motor-1-8deg-5v/dp/9598650) with L9942 from ST.But i have some problem because the motor dont rotate uniformly (lose some step): My curre...
Migrating from Power board MB459 to IHM023V2
Posted on July 09, 2014 at 04:41All - to save you a bit of trouble, here is what I found when I migrated my existing power board (discontinued by ST) to the new IHM023V2 power board:1) The connector pin-out to the STM32F10X-128K-EVAL is identical.2)...
The new idea can be realized
Posted on May 27, 2014 at 18:26I have a new idea ,Motor running low speed with hall Sensor , When the motor in high speed switching for sensorless mode, Can be realized?
L6472 Current Setup
Posted on July 07, 2014 at 14:24I use the L6472 with step / direction inputs. Can I write to register 9 (TVAL_HOLD) at any time? I am polling the position counter to determine when the motor didn't move for a while. Then I switch from normal to stan...
