E00 Output Overcurrent fault in Weg CFW-08 Drive

-
E00 fault in Weg CFW-08 Drive indicates Output Overcurrent. This means the inverter's output current has exceeded the safe threshold during the motor's operation or acceleration phase.Cause:Short-circuit between two motor phases.Short-circuit between ground and one or more output phases.Motor cable capacitance to ground too high, causing peak current at the output.Inertia of the load too high, or acceleration ramp too short.P169 set too high.Undue set of P136 and/or P137 (in V/F control).Undue set of P178 and/or P409 (in vector control).IGBT transistor module is short-circuited.Remedy:Check wiring for short circuits. Check motor insulation. Adjust parameters P169, P136, P137, P178, or P409. Increase acceleration time. Note regarding long cables (>50m):High capacitance can cause E00. To fix: 1. Reduce switching frequency (P297). 2. Connect a load reactor in series with motor supply line (Refer to Section 8.16). Reset Method: Power-on, Manual, Auto-reset, or DI.

E01 DC Link Overvoltage fault in Weg CFW-08 Drive

-
E01 fault in Weg CFW-08 Drive indicates DC Link Overvoltage. This means the internal DC bus voltage has risen too high, usually due to rapid deceleration or high supply voltage.Cause:Power supply voltage too high (Ud > 410V for 200-240V models; Ud > 820V for 380-480V models).Load inertia too high or deceleration ramp too short.Setting of P151 too high.Remedy:Check input power supply voltage. Increase deceleration ramp time. Adjust P151 setting. Reset Method: Power-on, Manual, Auto-reset, or DI.

E04 Inverter Overtemperature fault in Weg CFW-08 Drive

-
E04 fault in Weg CFW-08 Drive indicates Inverter Overtemperature. This means the heat sink temperature is too high, potentially due to poor ventilation, fan failure, or high ambient heat.Cause:Ambient temperature too high (>40°C).Output current too high.Blower locked or defective.Blocked airflow.Remedy:Allow the inverter to cool down before trying to reset. Check blower installed inside. Check ambient temperature and ventilation. For types with internal RFI-filters, check for internal airflow overtemperature. Reset Method: Power-on, Manual, Auto-reset, or DI.

E05 Motor/Inverter Overload (Ixt Function) fault in Weg CFW-08 Drive

-
E05 fault in Weg CFW-08 Drive indicates a Motor or Inverter Overload. This means the system has been operating above its rated current limit for a duration that risks thermal damage.Cause:P156 set too low for the motor being used.Motor is under an actual overload condition.Remedy:Adjust P156 setting. Check motor load conditions. Reset Method: Power-on, Manual, Auto-reset, or DI.

E06 External fault in Weg CFW-08 Drive

-
E06 fault in Weg CFW-08 Drive indicates an External Fault signal. This means an external device (like a safety switch) connected to the digital inputs has triggered a trip.Cause:Ani DI (DI3 and/or DI4) programmed for external fault detection is open (not connected to GND - XC1).Remedy:Check external wiring and connection to GND (XC1). Reset Method: Power-on, Manual, Auto-reset, or DI.
