FAULT
RESET
(1)
POSSIBLE CAUSES
E00
Output
Overcurrent
(between phases)
Power-on
Manual (key )
Auto-Reset
DI
Short-circuit between two motor phases.
If this fault occurs during power-up, there may be a short.
Overcurrent Auto-Reset circuit between ground and one or more output
phases.
Inertia of the load too high, or acceleration ramp too short.
IGBT transistor module is short-circuited.
E01
DC Link
Overvoltage
Power supply voltage too high, generating in the DC link a voltage higher
than the allowed value:
Load inertia too high and acceleration ramp is too short.
E02
DC Link
Undervoltage
(Ud)
Power supply voltage too low, causing a DC link voltage lower than the al
-
lowed value (read the value at Parameter P004).
E04
Inverter
Overtemperature
Ambient temperature too high (> 50 ºC) and/or output current too high.
Blocked or defective fan.
Note: The heat sink overtemperature protection (E04) is activated when the
heat sink temperature (P008) reaches 103 ºC or 133 ºC for the 15.2 A model.
E05
Overload at output
I x t Function
Motor is under an actual overload condition.
E06
External Error
(digital input program for
ext. fault is open)
Wiring at DI1 to DI4 inputs is open (not connected to GND).
E08
CPU Error
Electrical noise.
E09
Program Memory
Error (Checksum)
Contact WEG Servicing
Memory with corrupted values.
E24
Programming error
It is automatically reset
when the incompatible
parameters are changed
Incompatible parameters were programmed.
E31
Keypad (HMI)
Connection Fault
Contact WEG Servicing
Inverter control circuit is defective.
Electrical noise in the installation (electromagnetic interference).
E41
Self- Diagnosis Fault
Contact WEG Servicing
Inverter power circuit is defective.
WEG Faults and Possible Causes
This section assists the user to identify and correct possible faults that can occur during the CFW-10 operation.
When a fault is detected, the inverter is disabled and the fault code is displayed on the readout in EXX form,
where XX is the actual fault code.
To restart the inverter after a fault has occurred, the inverter must be reset. The reset can be made as follows:
disconnect and reapply the AC power (power-on reset);
press key
(manual reset);
The table below defines each fault code, explains how to reset the fault and shows the possible causes for each
fault code.
