PRODUCTION DATA
With all other operating conditions remaining constant, change in the ATQ_CNT value can be correlated to the motor case temperature variation, as shown below for a stepper motor with 25 Ω coil resistance. This property can be used in applications to monitor the PCB and motor temperature. By monitoring changes in motor temperature over time, system robustness can be increased and predictive maintenance of the motor can be performed.
