0056 TECH LIB CRITICAL
(0x6382)
Permanent fault generated
by a technology library.
Refer to the documentation of the
technology library.
0057 FORCED TRIP
(0xFF90)
Generic Drive
Communication Profile trip
command.
Check PLC status.
0058 FB PAR ERROR
(0x6320)
The drive does not have a
functionality requested by
PLC, or requested
functionality has not been
activated.
Check PLC programming.
Check settings of parameter group 50
Fieldbus.
0059 STALL
(0x7121)
Programmable fault: 30.09
Stall function
Motor is operating in stall
region because of e.g.
excessive load or
insufficient motor power.
Check motor load and drive ratings.
Check fault function parameters.
0060 LOAD CURVE
(0x2312)
Programmable fault: 34.01
Overload func / 34.02
Underload func
Overload or underload limit
has been exceeded.
Check the settings of the parameters in
group 34 User load curve.
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 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.
