Part Number:DRV8834
Hello sir,
I am working with drv8834.i am running 20dam20i0-k stepper motor from portescap.
i am running motor in indexer mode.
when i stared working with this driver IC i was able to run motor in a propper manner.and motor was running perfectly.but now some how motor is not running even with the same code.there is no change in code.
i have measured frequency at step pin.i am getting pulse on step pin as well as AOUT1,AOUT2,BOUT1 and AOUT2 connected to motor..state of other pins are as followed.
DIR = either high or low(through GPIO).
Enable = low.
sleep = high.
i have sense resistor value is 0.01E at AISEN and BISEN.
m1,m0 low for 1 microstepping.
please help me.any help will be greatly appreciable.
thanks
