5.2 Common Faults
When operating the Altivar 320, several fault conditions may arise. The most frequent are over‑current, over‑temperature, and communication errors. Over‑current typically indicates a short in the motor or a blockage in the drive’s cooling system; the drive will trip and display a “CC” fault code. Over‑temperature faults occur when the ambient temperature exceeds the rated limit or when the fan fails; the drive will show a “HT” code and shut down to protect the electronics. Communication faults, such as “CAN‑ERR” or “MODBUS‑ERR”, point to cable damage, incorrect baud rates, or incompatible device settings. Other common issues include “VOLT‑ERR” for supply voltage irregularities, “DUTY‑ERR” for incorrect duty cycle settings, and “SYNC‑ERR” when the drive loses synchronization with a master controller. Each fault is accompanied by a diagnostic code in the drive’s status display; refer to the fault‑code table in the user manual for detailed troubleshooting steps. Regular inspection of cables, connectors, and the drive’s environment, combined with firmware updates, can prevent many of these faults from occurring.
