We use micro controller STM32F103RBT6 & stepper motor driver IC TB6560AHQ.

we have found the problem at Reset pin of stepper motor driver IC. Circuit is attached.

Initially machine works properly. but after some time motor gets stop.

During analysis of the problem we observed that the resistor value at location R83( 10KOhm) shows 0.7Ohm.

& voltage at reset pin is 0V.

Kindly suggest
