What to do if WEG CFW-11 show Power Module W Fault?
If your WEG DC drive displays a Power Module W Fault (F038), it indicates a short-circuit between motor phases W and U or W and V. Check for short circuits in the motor wiring.
What to do if WEG CFW-11 show DB IGBT Fault?
If your WEG DC drive displays a DB IGBT Fault (F042), it indicates a short-circuit between the connection cables of the dynamic braking resistor. Check the connection cables of the dynamic braking resistor.
What causes A088 Keypad Comm. Fault in WEG CFW-11 DC Drives?
A Keypad Comm. Fault (A088) in WEG DC Drives can be caused by a loose keypad cable connection or electrical noise in the installation. Check keypad connections and mitigate electrical noise.
What causes A090 External Alarm in WEG CFW-11?
An External Alarm (A090) in WEG DC Drives can occur if wiring was not connected to the digital input (DI1 to DI8) set to “No external alarm”. Connect wiring to the correct digital input.
What causes A128 Timeout for Serial Communication in WEG DC Drives?
A Timeout for Serial Communication (A128) in WEG DC Drives suggests you check the wiring and grounding installation. Ensure proper wiring and grounding for communication.
What causes CPU Watchdog fault in WEG CFW-11 DC Drives?
A CPU Watchdog fault (F080) in WEG DC Drives is caused by electrical noise. Implement measures to reduce electrical noise.
What causes a DC Link Overvoltage (F022) fault on a WEG Inverter?
The WEG Inverter shows a DC Link overvoltage condition. This can be due to the input voltage being too high, exceeding permitted values (Ud > 400 V for 220/230 V input models or Ud > 800 V for 380/480 V input models). It can also be caused by high load inertia, short deceleration time, or incorrect settings for parameters P0151, P0153, or P0185.
What does it mean when my WEG Inverter displays an A047 IGBT Overload Alarm?
The WEG Inverter indicates an IGBT overload alarm because the inverter output current is too high.
