Posted on January 15, 2018 at 10:45HiThe L6480 absolute position counter seems to count in multiples of 256 micro steps? When executing the move command with a 1000 micro steps or using the GoToDir command with a 1000 micro step value both generate ...
Posted on February 20, 2018 at 16:13The data sheet for the 6470 (and 6472) is not clear regarding the SPI clock rate. what is your take on this? the reason why i ask is that a clock rate was selected, boards were built and deployed. all was well. ne...
Hello all!We are using L6470 in our product for stepper motor control. We are using the SPI mode control with MOVE command.I would like to know the time (relative to given external clock) it takes to run the motor for given distance, given max speed ...
Hello, I am designing Stepper driver for NEMA17 motors which going to operate within range of 300RPM max. I am planning to use 42V to supply the motor and torque tests shows that 1A is sufficient to obtain the target. What I have noticed on the firs...
STEF01 has an interesting price but requires an external power MOSFET for reverse polarity protection. I see from the datasheet that ST has performed some measurements using external FETs, so which one would you recommend?NOTE: This question and answ...
We are using an ST1S12GR device and the input current is >2.5mA even with only the feedback loop connected and ENable pin connected to Vin. Feedback resistors values are 220k resp. 59k. According to Datasheet Table 8 (“Electrical Characteristics�?) Q...
We are considering to use L6924U for a new design for a battery charging circuit in our industrial wireless remote controller project. If we set up L6924U for AC input (MODE grounded), do we need to do anything with IUSB pin? Can we just ground it (w...
We are using L6470PD driver IC for driving 2-phase stepping motor. Problem is related to external clock and internal clock setting in L6470.In fact, we noticed different motor rotation speed when we switch between external clock of 16MHz and internal...
We are building a 115kHz SMPS transformer that is being used in a circuit using a VIPER06HS. It is in the circuit with my transformer that is outputting 5 volts at 200mA the OCP is tripping off the VIPER unit. I would like to know how the OCP works. ...
