A4A1 IGBT overtemperature Estimated drive IGBT
temperature is excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
A4A9 Cooling Drive module temperature is
excessive.
Check ambient temperature. If it exceeds
40%/104 °F (frames R4
…R8) or if it
exceeds 50% /122 °F (frames R0
…R8),
ensure that load current does not exceed
derated load capacity of drive. See
chapter Technical data, section Derating
in the Hardware manual of the drive.
Check drive module cooling air flow and
fan operation.
Check inside of cabinet and heatsink of
drive module for dust pick-up. Clean
whenever necessary.
A4B0 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 drive power.
A4B1 Excess temperature
difference
High temperature difference
between the IGBTs of different
phases.
Check the motor cabling.
Check cooling of drive module(s).
A4F6 IGBT temperature Drive IGBT temperature is
excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
A580 PU communication Communication errors
between drive control unit and
power unit.
Check connections between drive control
unit and power unit and value of
parameter 95.04 Control board supply.
A581 Fan Cooling fan feedback missing. Check the auxiliary code to identify the
fan. Code 0 denotes main fan 1. Other
codes (format XYZ): “X” specifies state
code (1: ID run, 2: normal). “Y” = 0, “Z”
specifies the index of the fan (1: Main fan
1, 2: Main fan 2, 3: Main fan 3). Check
fan operation and connection. Replace
fan if faulty.
A582 Auxiliary fan missing An auxiliary cooling fan
(connected to the fan
connectors on the control
board) is stuck or
disconnected.
Check the auxiliary code.
Check auxiliary fan(s) and connection(s).
Replace faulty fan.
Make sure the front cover of the drive is
in place and tightened. If the
commissioning of the drive requires that
the cover is off, this warning will be
generated even if the corresponding fault
is defeated. See fault 5081 Auxiliary fan
broken (page 427).
0001 Auxiliary fan 1 missing.
0002 Auxiliary fan 2 missing.
