When a fault occurs, the CVF-S1 stops the motor and displays an error code on the LED screen. Refer to this quick-reference matrix to diagnose the issue: Fault Code Fault Description Potential Causes Overcurrent during acceleration/deceleration Acceleration time too short; Motor load is too heavy. Increase b-07 / b-08 values; Check motor size. E.OU1 / E.OU2 Overvoltage during deceleration/steady run Deceleration time too short; Surge in input voltage. Increase deceleration time; Install a braking resistor. E.LU Undervoltage
