Fault messages generated by the drive
CODE FAULT CAUSE WHAT TO DO
0001 OVERCURRENT
(2310)
0305 bit 0
Output current has exceeded
trip level. Check motor load.
Check acceleration time (
2202 and 2205 ).
Check motor and motor cable (including phasing).
Check ambient conditions. Load capacity decreases
if installation site ambient temperature exceeds
40°C. See section
Derating on page 291 .
0002 DC OVERVOLT
(3210)
0305 bit 1
Excessive intermediate circuit
DC voltage. DC overvoltage trip
limit is 420 V for 200 V drives
and 840 V for 400 V drives. Check that overvoltage controller is on (parameter
2005 OVERVOLT CTRL).
Check input power line for static or transient
overvoltage.
Check brake chopper and resistor (if used). DC
overvoltage control must be deactivated when brake
chopper and resistor is used.
Check deceleration time (
2203 , 2206 ).
Retrofit frequency converter with brake chopper and
brake resistor.
0003 DEV OVERTEMP
(4210)
0305 bit 2
Drive IGBT temperature is
excessive. Fault trip limit is
135°C. Check ambient conditions. See also section Derating
on page 291 .
Check air flow and fan operation.
Check motor power against unit power.
0004 SHORT CIRC
(2340)
0305 bit 3
Short circuit in motor cable(s) or
motor Check motor and motor cable.
0006 DC UNDERVOLT
(3220)
0305 bit 5
Intermediate circuit DC voltage
is not sufficient due to missing
input power line phase, blown
fuse, rectifier bridge internal
fault or too low input power. Check that undervoltage controller is on (parameter
2006 UNDERVOLT CTRL).
Check input power supply and fuses.
0007 AI1 LOSS
(8110)
0305 bit 6
(programmable fault
function
3001 , 3021 )
Analog input AI1 signal has
fallen below limit defined by
parameter
3021 AI1 FAULT
LIMIT.
Check fault function parameter settings.
Check for proper analog control signal levels.
Check connections.
0008 AI2 LOSS
(8110)
0305 bit 7
(programmable fault
function
3001 , 3022 )
Analog input AI2 signal has
fallen below limit defined by
parameter
3022 AI2 FAULT
LIMIT.
Check fault function parameter settings.
Check for proper analog control signal levels.
Check connections.
