0061 SPEED FEEDBACK
(0x8480)
No speed feedback is
received.
Check the settings of the parameters in
group 19 Speed calculation.
Check encoder installation. See the
description of fault 0039 (ENCODER1)
for more information.
0062 D2D SLOT COMM
(0x7584)
Drive-to-drive link is set to use
an FMBA module for
communication, but no module
is detected in specified slot.
Check the settings of parameters 57.01
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.
0063 MOTOR TEMP2
(0x4313)
Programmable fault:
31.05 Mot temp2 prot
Estimated motor temperature
(based on motor thermal
model) has exceeded fault limit
defined by parameter 31.08
Mot temp2 fltLim.
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).
Measured motor temperature
has exceeded fault limit
defined by parameter 31.08
Mot temp2 fltLim.
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.
0064 IGBT OVERLOAD
(0x5482)
Excessive IGBT junction to
case temperature. This fault
protects the IGBT(s) and can
be activated by a short circuit
in the motor cable.
Check motor cable.
0065 IGBT TEMP
(0x4210)
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.
0066 COOLING
(0x4290)
Drive module temperature is
excessive.
Check setting of parameter 95.03 Temp
inu ambient.
Check ambient temperature. If it exceeds
40 °C (104 °F), ensure that load current
does not exceed derated load capacity of
drive. See the 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.
