If your WEG DC drive displays an F070 (2) Overcurrent/Short-circuit error, it indicates a short-circuit. This could be between two motor phases, in the dynamic braking resistor connection cables, or within the IGBT modules. Inspect the wiring and connections to identify and fix any shorts.
What to do if WEG DC Drives show F048 IGBTs Overload Fault?
If you receive an F048 IGBTs Overload Fault on your WEG DC drive, it means the inverter output current is too high. Reduce the output current to prevent the IGBTs from overloading.
What to do if WEG CFW-11 show F022 DC Bus Overvoltage?
If your WEG DC drive displays an F022 DC Bus Overvoltage error, it means the input voltage is too high, causing the DC bus voltage to exceed the maximum permitted value (Ud > 1000 V). Reduce the input voltage or adjust the settings for parameters P0151, P0153, or P0185.
What to do if WEG CFW-11 DC Drives show F050 IGBTs High Temperature U?
If your WEG DC drive shows F050 IGBTs High Temperature U, it indicates that the surrounding air temperature is too high (above 50 °C or 122 °F) and/or the output current is too high. Ensure proper cooling and check for excessive output current.
What to do if WEG CFW-11 show F021 DC Bus Undervoltage?
If your WEG DC drive displays an F021 DC Bus Undervoltage error, it indicates that the input voltage is too low, causing the DC bus voltage to drop below the minimum permitted value. Check the supply voltage and ensure it meets the required levels.
What causes A110 High Motor Temperature in WEG CFW-11 DC Drives?
A110 High Motor Temperature in WEG DC Drives is caused by excessive load at the motor shaft or an excessive duty cycle (too many starts/stops per minute). To resolve this, reduce the load and duty cycle for the motor.
How to fix A047 IGBTs Overload Alarm on WEG CFW-11?
The A047 IGBTs Overload Alarm on WEG DC Drives means the inverter output current is too high. Reduce the output current to the IGBTs.
How to troubleshoot A046 High Load on Motor with WEG CFW-11 DC Drives?
If you are experiencing A046 High Load on Motor with your WEG DC Drive, it means that the settings of P0156, P0157, and P0158 are too low for the motor being used, or the motor shaft load is excessive. Adjust the settings of P0156, P0157, and P0158 based on the motor specifications.
What causes F006 Imbalance or Input Phase Loss in WEG CFW-11?
F006 Imbalance or Input Phase Loss in WEG DC Drives is caused by a missing phase at the inverter's input power supply or an input voltage imbalance greater than 5%. Reset the inverter and monitor the inputs.
What causes F174 (4) Left Fan Speed Fault in WEG CFW-11?
The F174 (4) Left Fan Speed Fault in WEG DC Drives is caused by dirt on the blades and in the bearings of the fan, or a defective fan. Clean or replace the left fan.
