Table 9 Faults.
Fault Code Name Description
1
OVERCURRENT
Output current is excessive.
•
Motor load may be too high
• Acceleration time may be too short (parameters 2201
ACCELER
TIME
1 and 2203
ACCELER TIME
2).
• Motor or motor cable is faulty or connected wrong.
2
DC OVERVOLTAGE
Intermediate circuit DC voltage is excessive.
•
Check mains for static or transient overvoltages
• Deceleration time may be too short (parameters 2202
DECELER
TIME
1 and 2204
DECELER TIME
2)
• Brake chopper (if present) may be underdimensioned
3
ACS
160
OVERTEMP
ACS 160 heat sink temperature is excessive. Temperature trip limit is
105 °C.
•
Check air flow and fan operation.
• Check motor power against unit power.
4 **
SHORT CIRCUIT
Fault current. Possible reasons for this fault are:
•
There is a short-circuit in the motor cable(s) or motor
• Supply disturbances
5
OUTPUT OVERLOAD
Inverter overload condition. The ACS 160 output current exceeds the
ratings given in Reference Section
P .
6
DC UNDERVOLTAGE
Intermediate circuit DC voltage is not sufficient.
•
Mains phase may be missing
• Fuse may be blown
7
ANALOGUE INPUT
1 Analogue input 1 loss. Analogue input value is less than
MINIMUM AI
1
(1301). See also parameter 3001
AI

MIN FUNCTION
.
8
ANALOGUE INPUT
2 Analogue input 2 loss. Analogue input value is less than
MINIMUM AI
2
(1306). See also parameter 3001

MIN FUNCTION
.
9
MOTOR OVERTEMP
Motor overtemperature condition as estimated by the ACS 160. Refer to
parameters 3004 – 3008.
10
PANEL LOSS
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 parameterised
to accept start/stop, direction or reference from the panel. Refer to
parameters in groups 10 COMMAND INPUTS and 11 REFERENCE
SELECT.

PARAMETERING
Parameter values are inconsistent:
•
MINIMUM AI
1 >
MAXIMUM AI
1 (parameters 1301, 1302)
•
MINIMUM AI
2 >
MAXIMUM AI
2 (parameters 1304, 1305)
•
MINIMUM FREQ
>
MAXIMUM FREQ
(parameters 2007, 2008)
12
MOTOR STALL
Motor stall. This may be caused by excessive load or insufficient motor
power. Refer to parameters 3009 – 3012.
13
SERIAL COMM LOSS
Serial communication through Standard Modbus Channel is lost.
•
Check connections between external control system and the
ACS 160.
• Refer to parameters 5204
COMM FAULT TIME
and 5205
COMM FAULT
FUNC
.
14
EXTERNAL FAULT SIGNAL
External fault is active. See parameter 3003
EXTERNAL FAULT
.
15 **
OUTPUT EARTH FAULT
Earth fault. The load on the incoming mains system is out of balance.
•
There may be a fault in the motor or motor cable.
• Motor cable may be too long.
16 **
DC BUS RIPPLE
• Ripple voltages on the DC bus are too large.
• Mains phase may be missing
• Fuse may be blown
