Fehlerbehebung

Fehlercode	Fault Cause	Fehlerbehebungsmethode
OV	DC bus overvoltage	Netzspannung prüfen, extend deceleration time, install braking unit.
UV	DC bus undervoltage	Netzspannung prüfen, shorten acceleration time, check input phase loss.
OC	Output overcurrent	Check insulation of motor and cables, Belastung reduzieren, extend acceleration time.
OH	Frequency converter overtemperature	Check cooling fan, clean air duct, reduce ambient temperature.
PH	Input phase loss	Check input power supply, tighten wiring terminals, replace damaged fuses.
GF	Erdschluss	Check insulation of motor and cables, eliminate ground fault points.

VII. Installation and Wiring Key Points

Vor der Installation, confirm that the power supply voltage matches the rated voltage of the frequency converter, disconnect the power supply and verify no voltage.
Adopt 35mm DIN rail mounting or wall-mounted mounting to ensure sufficient heat dissipation space.
Verkabelung des Hauptstromkreises: R/L1, S/L2, T/L3 are inputs; U, V, W are outputs; PE is the grounding terminal.
Verkabelung des Steuerkreises: Shielded wires should be used for analog input, with the shielding layer grounded at one end; digital input should avoid routing in the same slot as high-voltage electricity.
Check parameter settings before power-on, especially basic parameters such as motor rated power, rated current and rated frequency.
