"COMM LOSS" (ACS-PAN) Serial link failure. Bad connection between the control panel and the
ACS 400.
Note! Faults (*) that are indicated by a red blinking LED are reset by turning the power off and
on. Other faults are reset from the control panel. See parameter 1604

Overcurrent:
• Possible mechanical problem.
• Acceleration and/or deceleration times may be too short.
• Power supply disturbances.
DC overvoltage:
• Input voltage too high.
• Deceleration time may be too short.
ACS 400 overtemperature:
• Ambient temperature too high.
• Severe overload.
Fault current:
• Short circuit.
• Power supply disturbances.
Analog input 1 fault. Analog input 1 value is less than
(1301). See also parameter 3001
Analog input 2 fault. Analog input 2 value is less than
(1304). See also parameter 3001
Motor overtemperature. See parameters 3004-3008.
Panel loss. Panel is disconnected when Start/Stop/Dir or reference
is coming from panel. See parameter 3002 and APPENDIX.
Note! If FL10 is active when the power is turned off, the ACS 400
will start in remote control (REM) when the power is turned back on.
Parameters inconsistent. Possible fault situations:
• AI1 >

Motor stall. See parameter 3009
External fault is active. See parameter 3003
Output ground fault.
DC bus ripple too high. Check power supply for phase loss or
imbalance.
Underload.
Reserved.
