Fault
code Fault
description Cause Actions
0x2315 Motor
overcurrent Short Circuit detected in U phase
Try to reset the error.
If error returns, contact Atlas Copco. 0x2316 Motor
overcurrent Short Circuit detected in V phase
0x2317 Motor
overcurrent Short Circuit detected in W phase
0x3210 Overvoltage Overvoltage detected
Check if main supply voltage is within
specs. Check main fuses.
0x3221 Undervoltage Main Power supply voltage too low.
0x3223 Undervoltage Phase loss detected
0x3224 Overvoltage Maximum allowable voltage of the DC-
link exceeded; Threshold is lowered in
case of higher temperature Let drive cool off
Check for excessive ambient
temperature
Clean heatsink with compressed air
Clean inlet filter cubicle
Ensure proper flow of cooling air in
compressor room
Check if supply voltage is within
specs
0x3225 Undervoltage Undervoltage detected Check if main supply voltage is within
specs.
Check main fuses.
0x3226 Overvoltage Overvoltage or overtemperature
detected in IGBT (U phase) Let drive cool off.
Check for excessive ambient
temperature.
Clean heatsink with compressed air.
Clean inlet filter cubicle.
Ensure proper flow of cooling air in
compressor room.
Check if supply voltage is within
specs.
0x3227 Overvoltage Overvoltage or overtemperature
detected in IGBT (V phase)
