ZHCSDA7G July 2014 – February 2018 DRV10983
When the motor is blocked or stopped by an external force, the lock protection is triggered, and the device stops driving the motor immediately. After the lock release time tLOCK_OFF, the DRV10983 resumes driving the motor again. If the lock condition is still present, it enters the next lock protection cycle until the lock condition is removed. With this lock protection, the motor and device does not get overheated or damaged due to the motor being locked (see Lock Detect and Fault Handling).
During lock condition, the MtrLck Status bit (address 0x10, bit 4) is set. To further diagnose, check the register FaultCode.
