540 Fault tracing
AE0C BU DC link difference
DC link voltage difference
detected by the branching unit.
Check DC fuses.
Check converter module connections to
DC link.
AE0D BU voltage difference
Main voltage difference
detected by the branching unit.
Check AC fuses.
Check supply cable.
AE14
Excess temperature
Power unit module
temperature is excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against IGBT supply
unit power.
AE15
Excess temperature
difference
High temperature difference
between the IGBTs of different
phases.
Check the cabling.
Check cooling of power module(s).
AE16
IGBT temperature
IGBT temperature is
excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against IGBT supply
unit power.
AE24
Voltage category
unselected
The supply voltage range has
not been defined.
Define the supply voltage range
(parameter
).
AE5F
Temperature Warning
Supply module temperature is
excessive due to eg, module
overload or fan failure.
Check module cooling air flow and fan
operation.
Check ambient temperature. If it exceeds
40 °C (104 °F), ensure that load current
does not exceed derated load capacity.
See appropriate hardware manual.
Check inside of cabinet and heatsink of
supply module for dust pick-up. Clean
whenever necessary.
AE73
Fan
Cooling fan is stuck or
disconnected.
Check the auxiliary code in the line-side
converter program to identify the fan.
Check fan operation and connection.
Replace fan if faulty.
AE78
Net lost
Net lost is detected.
Resynchronize the IGBT supply unit to
the grid after net lost.
AE85
Charging count
There are too many DC link
charging attempts.
Two attempts in five minutes is allowed to
prevent charging circuit overheating.
