CAUSE
WHAT TO DO
0001
OVERCURRENT
(2310)
bit 0
Output current has
exceeded trip level.
Check motor load.
Check acceleration time (
and
Check motor and motor cable
(including phasing).
Check ambient conditions. Load
capacity decreases if installation site
ambient temperature exceeds 40 °C.
See section
on page
0002
DC OVERVOLT
(3210)
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
).
Check input power line for static or
transient overvoltage.
Check deceleration time (
0003
DEV OVERTEMP
(4210)
bit 2
Drive IGBT
temperature is
excessive. Fault trip
limit is 135 °C.
Check ambient conditions. See also
section
on page
.
Check air flow and fan operation.
Check motor power against drive
power.
0004
SHORT CIRC
(2340)
bit 3
Short circuit in motor
cable(s) or motor
Check motor and motor cable.
0006
DC UNDERVOLT
(3220)
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
).
Check input power supply and fuses.
0007
AI1 LOSS
(8110)
bit 6
(programmable fault
function
,
)
Analog input AI1 signal
has fallen below limit
defined by parameter
Check fault function parameter
settings.
Check for proper analog control signal
levels.
Check connections.
0008
AI2 LOSS
(8110)
bit 7
(programmable fault
function
,
)
Analog input AI2 signal
has fallen below limit
defined by parameter
Check fault function parameter
settings.
Check for proper analog control signal
levels.
Check connections.
