Programmable alarm: 31.05
Mot temp2 prot
Estimated motor
temperature (based on
motor thermal model) has
exceeded alarm limit
defined by parameter 31.07
Mot temp2 almLim.
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
alarm limit defined by
parameter 31.07 Mot temp2
almLim.
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.
2050 IGBTOLALARM
(0x5482)
08.08 Alarm word4 b3
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.
2051 IGBTTEMPALARM
(0x4210)
08.08 Alarm word4 b4
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.
2052 COOLALARM
(0x4290)
08.08 Alarm word4 b5
Drive module temperature is
excessive.
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.
