9.6.4 - Compressor drive alarms/alerts
Compressor drive alarms or alerts are displayed based on
the following formula: 17+X-YYY for alarms and 35+X-YYY
for alerts (X stands for the number of the circuit and YYY
is the alarm/alert code).
The tables below present the most common alarms associated
with the variator malfunction. Please refer to the applicable
Danfoss documentation for more information on other
alarms.
Code Description Action to be taken
Drive alarms
4 Mains phase loss Check the VFD supply voltage and the phase balance (±3%)
7 Over voltage Contact Carrier Service
8 Under voltage Contact Carrier Service
9 Inverter overloaded Check the VFD output current/compressor current
12 Torque limit exceeded Check the VFD output current/compressor current
13 Overcurrent Check the VFD output current/compressor current
14 Earth fault Check if an earth fault exists
16 Motor short-circuit Check if there is a short-circuit at the VFD terminals
23* Internal fan fault Check the internal fan rotation
29 VFD temperature too high Space temperature too high or VFD ventilation obstructed or damaged
30 Motor phase U missing Check wiring of phase U
