42F1 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.
4310 Excess temperature Power unit module
temperature is excessive.
See A4B0 Excess temperature (page
348).
4380 Excess temperature
difference
High temperature difference
between the IGBTs of different
phases.
See A4B1 Excess temperature
difference (page 349).
4981 External temperature
1
(Editable message text)
Measured temperature 1 has
exceeded fault limit.
Check the value of parameter 35.02
Measured temperature 1.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check the value of parameter 35.12
Temperature 1 fault limit.
4982 External temperature
2
(Editable message text)
Measured temperature 2 has
exceeded fault limit.
Check the value of parameter 35.03
Measured temperature 2.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check the value of parameter 35.22
Temperature 2 fault limit.
5080 Fan
Programmable fault: 31.35
Main fan fault function
Cooling fan feedback missing. See A581 Fan (page 349).
5081 Auxiliary fan not
running
Programmable fault: 31.36
Aux fan fault function
An auxiliary cooling fan
(connected to the fan
connectors on the control unit)
is stuck or disconnected.
See A582 Auxiliary fan not running (page
350).
5090 DIL hardware failure Drive interlock hardware
failure.
Contact your local ABB representative,
quoting the auxiliary code. The code
contains location information, especially
with parallel-connected inverter modules.
When converted into a 32-bit binary
number, the bits of the code indicate the
following:
31…28: Number of faulty inverter module
(0…11 decimal). 1111: DIL_ACT states of
control unit and inverter modules in
conflict
27: DIL_ACT state of inverter modules
26: DIL_ACT state of control unit
25: DIL1 of control unit
24: DIL2 of control unit
23…12: DIL1 of inverter modules 12…1
(Bits of non-existing modules set to 1)
11…0: DIL2 of inverter modules 12…1
(Bits of non-existing modules set to 1)
5091 Drive interlock
Programmable fault: 31.22
Drive interlocked
Drive interlock function is
active, i.e. safety circuit
signal(s) connected to
connector XDIL is broken
during start or run.
Check Drive interlock circuit connections.
For more information, see appropriate
drive hardware manual and description of
parameter 31.22 Drive interlocked (page
204).
