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,...
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...
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...
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)...
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?
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...
Posted on July 01, 2014 at 01:11I'd like to enable the HardStop interrupt (i.e. SW_MODE = 0) when I home my motor and then disable it afterward so that subsequent moves do not trigger the interrupt. Enabling the interrupt before I start homing via ...

Posted on June 26, 2014 at 03:57I'm builting a mini drive using the L6474. Got it all working and it runs smooth, but the driver runs very hot and I measured the charge pump and the voltage is only 5volts p-p max (manual says it should be 10vp-p) ...
Posted on July 07, 2014 at 07:39Hi,Now that I can communicate with my dSpins without losing the high order bits, I find that there are a few registers that I can't read back to verify my setting.1) I always get zero reading the FS_SPD register so I ...
