A fault code displayed on a motor drive could indicate a(n) ___.

• A. Loss of Phase
• B. Undervoltage Condition
• C. Drive Overload
• D. Any of These

Answer: (D)

Fault codes on a motor drive are diagnostic signals that indicate protection events or abnormal operating conditions. Because the drive monitors many different parameters, a single fault code can correspond to a variety of problems. For example, losing a phase disrupts balance and torque, an undervoltage condition means the supply isn’t meeting what the drive needs, and an overload occurs when the motor tries to draw more current than allowed. There are also other possible faults the drive can report. So the fault code could indicate any of these situations, making “Any of These” the best choice. Check the drive’s fault code table in the manual to interpret the exact meaning of a specific code.
