Description
Output current is excessive.
•
•
•
Intermediate circuit DC voltage is excessive.
•
•
•
ACS 400 heat sink temperature is excessive. Temperature trip limit is
OVERTEMP
95 °C.
•
•
Fault current. Possible reasons for this fault are:
•
•
Inverter overload condition. The ACS 400 output current exceeds the
ratings given in "Specifications" on page 21 of this manual.
Intermediate circuit DC voltage is not sufficient.
•
•
1 Analog input 1 loss. Analog input value is less than
See also parameter 3001
2 Analog input 2 loss. Analog input value is less than
See also parameter 3001
Motor overtemperature condition as estimated by the ACS 400. Refer
to parameters 3004 – 3008.
Panel communication loss. Control panel is disconnected when the
drive is receiving start, stop and direction commands from the panel.
- Drive is in local control mode (LOC is shown in the control panel
display), or
- Drive is in remote control mode (REM is shown) and is programmed to
accept start/stop, direction or reference from the panel. Refer to
parameters in groups 10 COMMAND INPUTS and 11 REFERENCE
SELECT.

Parameter values are inconsistent:
•
•
•
•
Motor stall. This may be caused by excessive load or insufficient motor
power. Refer to parameters 3009 – 3012.
Serial communication through Standard Modbus Channel is lost.
•
•
External fault is active. See parameter 3003
Ground fault. The load on the input power system is out of balance.
