WHAT TO DO
F0001
OVERCURRENT
Output current has exceeded trip
level.
Overcurrent trip limit for drive is
325% of drive nominal current.
Check motor load.
Check acceleration time (parameters 2202
ACCELER TIME 1 and 2205 ACCELER TIME 2).
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 138.
F0002
DC OVERVOLT
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 brake chopper and resistor (if used). DC
overvoltage control must be deactivated when brake
chopper and resistor are used.
Check deceleration time (parameters 2203
DECELER TIME 1 and 2206 DECELER TIME 2).
Check input power line for static or transient
overvoltage.
Retrofit frequency converter with brake chopper and
brake resistor.
F0003
DEV OVERTEMP
Drive IGBT temperature is
excessive. Fault trip limit is
135 °C.
Check ambient conditions. See also section Derating
on page 138.
Check air flow and fan operation.
Check motor power against drive power.
F0004
SHORT CIRC
Short circuit in motor cable(s) or
motor
Check motor and motor cable.
F0006
DC UNDERVOLT
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.
F0007
AI1 LOSS
(programmable
fault function,
parameters 3001
AI<MIN
FUNCTION, 3021
AI1 FAULT LIMIT)
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.
F0009
MOT OVERTEMP
(programmable
fault function,
parameters
3005...3009)
Motor temperature is too high (or
appears to be too high) due to
excessive load, insufficient motor
power, inadequate cooling or
incorrect start-up data.
Check motor ratings, load and cooling.
Check start-up data.
Check fault function parameter settings.
Let motor cool down. Ensure proper motor cooling:
Check cooling fan, clean cooling surfaces, etc.
F0012
MOTOR STALL
(programmable
fault function,
parameters
3010…3012)
Motor is operating in stall region
due to, for example, excessive
load or insufficient motor power.
Check motor load and drive ratings.
Check fault function parameter settings.
