If a stepper motor is not responding to control signals and remains stationary, what could be a possible cause?
A. Sufficient power supply voltage
B. Faulty motor driver circuit
C. Less load torque
D. Incorrect micro-stepping resolution
Answer:B
If a stepper motor is not responding to control signals and remains stationary, what could be a possible cause?
A. Sufficient power supply voltage B. Faulty motor driver circuit C. Less load torque D. Incorrect micro-stepping resolution
Explanation: A faulty motor driver circuit can cause a stepper motor to not respond to control signals and remain stationary. The motor driver is responsible for translating the control signals into motor movement, and any issues with the driver circuit can result in no motor response.
