What causes E01 DC Link Overvoltage in WEG Inverters and how to fix it?
The E01 error on your WEG Inverter indicates a DC Link Overvoltage. This can be due to: * Power supply voltage being too high: Check and adjust the power supply voltage. * Load inertia being too high or deceleration ramp too short: Adjust the load inertia or deceleration ramp settings. * P151 setting being too high: Lower the setting of P151.
Why does my WEG Inverter show E04 Inverter Overtemperature and how can I resolve it?
The E04 error on a WEG Inverter signals an overtemperature condition. This can occur if: * The ambient temperature is too high (above 40°C) or the output current is too high: Ensure the ambient temperature is below 40°C and lower the output current. * The blower is locked or defective: Check, repair, or replace the blower.
What to do if WEG Inverter displays E05 Motor/Inverter Overload Ixt Function error?
If your WEG Inverter shows error E05, indicating a Motor/Inverter Overload, consider these possibilities: * P156 is set too low for the motor being used: Increase the setting of P156. * The motor is under an actual overload condition: Remove the overload condition from the motor.
How to troubleshoot E14 Self-Tuning Fault on a WEG CFW08 Vector?
If your WEG Inverter displays an E14 error, indicating a Self-Tuning Fault, check the following: * Motor connection: Ensure the motor is connected to the inverter output. * Motor wiring: Verify correct motor connection (voltage, phase). * Motor size: Replace with a compatible motor if the used motor is too small for the inverter (P401
What causes E31 Keypad (HMI) Connection Fault on WEG Inverters?
The E31 error on your WEG Inverter indicates a Keypad (HMI) Connection Fault. This can be due to: * Keypad cable misconnection: Recheck and correct the keypad cable connections. * Electrical noise: Reduce electrical noise in the installation.
What does E06 External Fault mean on my WEG CFW08 Vector and how to fix it?
The E06 error on your WEG Inverter indicates an External Fault. This occurs when Ani DI (DI3 and/or DI4) programmed for external fault detection is open (not connected to GND - XC1). To resolve it, check and connect DI3 or DI4 to GND.
What causes E10 Keypad Error on a WEG CFW08 Vector Inverter?
The E10 error on your WEG Inverter indicates a Keypad Error. This can occur due to: * Defective contact in the HMI-CFW08-RS cable: Check and replace the HMI-CFW08-RS cable. * Electrical noise: Reduce electrical noise in the installation (electromagnetic interference).
What does E08 CPU Error (Watchdog) mean on a WEG Inverter?
The E08 error on your WEG Inverter indicates a CPU Error (Watchdog). This is due to electrical noise. Reduce electrical noise in the installation.
