U:01
Note
The compressor is working out of envelope
· inverter temperature too high
· check the liquid valve and/or refrigerant load. The valve activates
when the oil exceeds 100°C and deactivates when it goes below
95°C
· failure of a phase or imbalance between phases
· inverter temperature sensor fault. Check the oil sensor and motor
sensor
· incorrect hardware configuration
· incorrect software configuration
· incorrect inverter parameters
· motor winding temperature above limits
· high oil temperature (check oil heater)
- warning if greater than 115°C
- fault if greater than 120°C
- reset alarm if less than 105°C
· compressor starting is requested before the minimum time
between two starts has passed. This occurs only at the Warning level
The compressor is working out of envelope
· power request from card pCO5+ to inverter timeout
