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 ...
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...
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 =...
Posted on June 26, 2014 at 12:43Hi, For our Medical Respirator equipment, We need Micro controller, Which is capable of controlling BLDC motor up to 60,000 RPM with minimum CPU utilization. Please suggest suitable microcontroller from ST. Thanks ...
Posted on May 25, 2013 at 00:01Hi Can one implement stall detection on the L6474? Thanks Andre
Posted on June 03, 2012 at 21:47hi , i am currently evaluate l6470 and have a few questions : 1. does the driver suitable for stepper motor with max 3A current per phase ? 2. how to obtain maximum holding torque ? ( setting K_HOLD to FFh ?) #go_u...
Posted on June 03, 2014 at 11:22The L6474 chip provides three ground pins (PGND, AGND, DGND) as well as a thermal pad (EPAD) connected internally to all three of the above. If I understand the chip's block diagram correctly (datasheet, p. 7), PGND a...
Posted on June 20, 2014 at 07:29HiI'm using L6470.It works to move step motor a bit,when the Powered on.The motor's coil Voltage was high between the RESET turn high and First SPI communication is started.(Almost 10ms?CPU's order)I don't want to m...
