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...
Problems with SW_MODE bit in CONFIG register
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 ...

L6474 Charge pump low...only 5 volts
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) ...
Can't read some registers
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 ...
L6470 get ABS_POS: 8th Bit always Low
Posted on November 30, 2012 at 16:43Hello ST!We are using the L6470 and it is working quite well. But: We have problems when reading the ABS_POS register. It seems to be that the 8th Bit (for 128) is always Low. See Our values: Go To Pos R...
Problems in Configuration of my L6482 board
Posted on March 23, 2014 at 11:37I have designed a board using a L6482 chip. My L6482 has started, and I can send and receive messages a través de SPI bus, but now I have a problem: My STATUS register says: 1110 0000 0000 0011 (Get Status Command =...
