The complete fault code list is detailed in the official Optidrive E3 manual, which should always be the primary reference.

Fixing Optidrive E3 Over Voltage Faults

Several common faults relate directly to the AC power supply. An "O-VOLT" (Over Voltage) fault, for example, typically occurs when the incoming line voltage is too high or when a high-inertia load drives the motor, causing it to act as a generator and increase the DC bus voltage. To resolve this, first verify that the supply voltage is within the drive's specified range as noted in its technical documentation. Subsequently, you might need to increase the deceleration time (Parameter P-04) to reduce the regenerative effect. Conversely, an "U-VOLT" (Under Voltage) trip indicates that the main supply has dropped too low, which can be caused by an unstable power source or undersized supply wiring. According to the official datasheet from Driveswarehouse, the drive has specific input voltage tolerances that must be maintained for proper operation.

Motor and load-related issues frequently trigger "O-CUR" (Over Current) or "I-TRIP" (Motor Overload) faults. An overcurrent fault is an instantaneous trip that happens when the output current exceeds the drive's limit, often due to a shorted motor winding, a seized load, or an excessively fast acceleration ramp. An overload trip, in contrast, is a timed function designed to protect the motor from sustained overcurrents. Troubleshooting these faults involves checking for any mechanical blockages, verifying the motor wiring integrity, and ensuring the motor data in the drive's parameters is correct. The Optidrive E3 drive also features a fault memory log that stores the last four trips, providing valuable historical data for diagnostics.
