Posted on September 18, 2014 at 17:37Hello!I bought 3 Eval-L9942 boards. I connected supply voltage (5V). Enable (connect to 5V) and a step clock (5V. 100Hz). The VS supply is 12V.The motor i have connected does not move. All outputs are at 12V cons...
Posted on August 29, 2014 at 03:19timer 1 output compare to generate Step output for stepper motorI am using timer1 channel 1 as output compare, to generate a pulse of variable period.Desire output – In the beginning the output remain low for 4 ms(...
Posted on August 21, 2014 at 22:41after performing a few sensor seeks using the ReleaseSW() and GoUntil() commands i have noticed that they do not use the same acceleration/deceleration. GoUntil() uses the programmed values, ReleaseSW() uses somethi...
Posted on September 15, 2014 at 16:23I'm investigating using the L6470 for an multi-axis application. Please let me now if it is possible using SPI to position multiple motors according to a motion profile/position table at constant speed. i.e. impl...
Posted on October 22, 2013 at 20:37I've been quite successful at controlling the L6470 stepper driver chip from my embedded ARM processor for all features other than the sensorless stall detection feature. I'm hoping that I'm missing something and t...
Posted on September 06, 2014 at 14:57Greetings, I am doing a test series of stepper drivers with L6480 for furnace rotation control. There seems to be a problem with the device. The circuit is a copy of Eval 6480. SPI is up and functional, every re...
Posted on September 03, 2014 at 09:59Hello!In my application I send GoTo(ABS_POS) commands when stepper motor is running at constant speed, when BUSY flag is high, so I'm sure that the target speed is reached. And everything is going well most of ti...
Posted on September 01, 2014 at 03:30HiI need help in identifying the VIPER or any other device for a 15W and 30W LED Driver for Street Light. The input is 150V to 310V AC @ 50Hz.ThanksKiran M R
Posted on September 01, 2014 at 03:27HiI need help on designing a 12V, 1A and 12V, 2A SLA Battery Charger. The input is 150V to 270V AC @ 50Hz.This is urgently required and would appreciate any help in this regard.ThanksKiran M R
Posted on August 03, 2014 at 06:34hello all : I,recently?found that the formula about duty cycle computation in the SW do not accord with that in the user manual . Sector ????TimePhA=T/8+?T+X-Z?/2 in the SW,however,Sector ????TimePhA=?T...
