Cause
No speed feedback is
received.
Drive-to-drive link is set to use
an FMBA module for
communication, but no module
is detected in specified slot.
Estimated motor temperature
(based on motor thermal
model) has exceeded fault limit
defined by parameter 31.08
Mot temp2 fltLim.
Measured motor temperature
has exceeded fault limit
defined by parameter 31.08
Mot temp2 fltLim.
Excessive IGBT junction to
case temperature. This fault
protects the IGBT(s) and can
be activated by a short circuit
in the motor cable.
Drive IGBT temperature is
excessive. Fault trip limit is
100%.
Drive module temperature is
excessive.
Firmware time level 2 overload
Note: This fault cannot be
reset.
Firmware time level 3 overload
Note: This fault cannot be
reset.
What to do
Check the settings of the parameters in
group 19 Speed calculation.
Check encoder installation. See the
description of fault 0039 (ENCODER1)
for more information.
Check the settings of parameters
and 57.15. Ensure that the FMBA
module has been detected by checking
parameters 09.20...09.22.
Check that the FMBA module is correctly
wired.
Try installing the FMBA module into
another slot. If the problem persists,
contact your local ABB representative.
Check motor ratings and load.
Let motor cool down. Ensure proper
motor cooling: Check cooling fan, clean
cooling surfaces, etc.
Check value of alarm limit.
Check motor thermal model settings
(parameters 31.09...31.14).
Check that actual number of sensors
corresponds to value set by parameter
31.06 Mot temp2 src.
Check motor ratings and load.
Let motor cool down. Ensure proper
motor cooling: Check cooling fan, clean
cooling surfaces, etc.
Check value of alarm limit.
Check motor cable.
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 °C (104 °F), ensure that load current
does not exceed derated load capacity of
drive. See appropriate Hardware Manual.
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.
