Table 7 Faults.
Note! Faults (*) that are indicated by a red blinking LED are reset by turning
the power off and on. Other faults are reset by pressing the START/STOP
button. See also parameter 1604.
Code Description
FL 1 Overcurrent:
• Possible mechanical problem.
• Acceleration and/or deceleration times may be too short.
• Supply disturbances.
FL 2 DC overvoltage:
• Input voltage too high.
• Deceleration time may be too short.
FL 3 ACS140 overtemperature:
• Ambient temperature too high.
• Severe overload.
FL 4 * Fault current:
• Output earth fault (200 V units).
• Short circuit.
• Supply disturbances.
FL 5 Output overload.
FL 6 DC undervoltage.
FL 7 Analogue input 1 fault. Analogue input 1 value is less than
MINIMUM
AI1 (1301). See also parameters 3001
AI<MIN FUNCTION and 3013 AI1
FAULT LIMIT.
FL 8 Analogue input 2 fault. Analogue input 2 value is less than
MINIMUM
AI2 (1304). See also parameters 3001
AI<MIN FUNCTION and 3014 AI2
FAULT LIMIT.
FL 9 Motor overtemperature. See parameters 3004-3008.
FL10 Panel loss. Panel is disconnected when Start/Stop/Dir or reference is
coming from panel. See parameter 3002
PANEL LOSS and APPENDIX.
Note! If FL10 is active when the power is turned off, the ACS140 will
start in remote control (REM) when the power is turned back on.
FL11 Parameters inconsistent. Possible fault situations:
•
MINIMUM AI1 > MAXIMUM AI1 (parameters 1301 and 1302)
•
MINIMUM AI2 > MAXIMUM AI2 (parameters 1304 and 1305)
•
MINIMUM FREQ > MAXIMUM FREQ (parameters 2007 and 2008)
FL12 Motor stall. See parameter 3009
STALL FUNCTION.
FL13 Serial communication loss.
FL14 External fault is active. See parameter 3003
EXTERNAL FAULT.
FL15 Output earth fault (400 V units).
FL16 * DC bus ripple too large. Check supply.
FL17 Analogue input out of range. Check AI level.
FL18 - FL22 * Hardware error. Contact supplier.

Serial link failure.
• Bad connection between the control panel and the ACS140.
• Serial communication parameters (group 52) have been altered.
Keep panel connected and switch power off and then on again.
