L6470
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...
L6474 grounding/layout recommendations
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...
L6470 Power ON and RESET
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...
Step-Clock Mode
Posted on June 17, 2014 at 11:15Dear all,I actually using two l6470 boards (to control two stepper motors), connected in daisy chain configuration also with STM32F4DIS-EXT.I don't understand very well how to control these drivers in STEP-CLOCK mode....
Control 2 motors (X and Y) with l6470 in daisy chain configuration
Posted on June 11, 2014 at 10:51Dear all,my question is about how to realize a syncronous movement of 2 stepper motor (one move in X direction and one move in Y direction), controlling by 2 l6470 connected in a daisy chain configuration also with ST...
