Cause
temperature is excessive.
Drive module temperature is
excessive.
Power unit module
temperature is excessive.
High temperature difference
between the IGBTs of different
phases.
Drive IGBT temperature is
excessive.
Communication errors
between drive control unit and
power unit.
Cooling fan feedback missing.
An auxiliary cooling fan
(connected to the fan
connectors on the control
board) is stuck or
disconnected.
0001 Auxiliary fan 1 missing.
0002 Auxiliary fan 2 missing.
What to do
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
Check ambient temperature. If it exceeds
40%/104 °F (frames R4
exceeds 50% /122 °F (frames R0
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.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
Check the motor cabling.
Check cooling of drive module(s).
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
Check connections between drive control
unit and power unit and value of
parameter 95.04 Control board
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.
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).
