414Mains ph. lossXXX
Missing phase on the supply side or too high voltage
imbalance. Check the supply voltage. See
parameter 14-12 Response to Mains Imbalance.
7 11 DC over volt X X – DC-link voltage exceeds the limit.
8 10 DC under volt X X – DC-link voltage drops below voltage warning low-limit.
9 9 Inverter overload X X – More than 100% load for a long time.
10 8 Motor ETR over X X –
The motor is too hot due to more than 100% load for a long
time. See parameter 1-90 Motor Thermal Protection.
11 7 Motor th over X X –
Thermistor or thermistor connection is disconnected. See
parameter 1-90 Motor Thermal Protection.

90 kW units).
30 19 U phase loss – X X
Motor phase U is missing. Check the phase. See
parameter 4-58 Missing Motor Phase Function.
31 20 V phase loss – X X
Motor phase V is missing. Check the phase. See
parameter 4-58 Missing Motor Phase Function.
32 21 W phase loss – X X
Motor phase W is missing. Check the phase. See
parameter 4-58 Missing Motor Phase Function.
38 17 Internal fault – X X Contact the local Trane supplier.
44 28 Earth Fault – X X
