Why WEG CFW11M G2 DC Drives show overcurrent/short circuit error?
The F070 error on WEG DC Drives indicates an overcurrent or short circuit, likely caused by a short circuit between two motor phases. To resolve this, inspect the motor for shorts.
What to do if WEG DC Drives show motor overload?
If your WEG DC Drives display a motor overload (F072), it means the load on the motor shaft is too high. You should reduce the load on the motor.
What to do if WEG CFW11M G2 show IGBTs overload fault?
If WEG DC Drives show an IGBTs Overload Fault (F048), it means the inverter output current is too high. Reduce the inverter output current.
How to fix WEG CFW11M G2 DC Drives output overcurrent fault?
The F071 fault on WEG DC Drives, which indicates an output overcurrent, is often due to load inertia being too high or the acceleration ramp being too fast. Decrease load inertia or adjust ramp settings to resolve this.
What causes WEG DC Drives to show DC link overvoltage?
A DC Link Overvoltage (F022) on WEG DC Drives is caused by a supply voltage that is too high, resulting in voltage on the DC link exceeding the maximum value. Ensure that the supply voltage is within specified limits.
What to do if WEG CFW11M G2 show ground fault?
If WEG DC Drives display a Ground Fault (F074), it indicates a short circuit to the ground in one or more output phases. Inspect for ground faults in wiring.
Why WEG CFW11M G2 DC Drives show IGBTs overload alarm?
The IGBTs Overload Alarm (A047) on WEG DC Drives indicates that the inverter output current is too high. Reduce the inverter output current.
How to fix motor overtemperature on WEG DC Drives?
If WEG DC Drives report a motor overtemperature (F078), it's because the load on the motor shaft is too high. You should reduce the load or enhance cooling.
What causes high motor temperature on WEG DC Drives?
High Motor Temperature (A110) in WEG DC Drives is caused by excessive load at the motor shaft. Reduce the load on the motor.
What to do if WEG CFW11M G2 show DC link undervoltage?
If WEG DC Drives display a DC Link Undervoltage (F021), the supply voltage is likely too low, causing the voltage on the DC link to fall below the minimum value. Verify supply voltage setting in parameter P0004.
