CAUSE
Output current has
exceeded trip level.
Excessive
intermediate circuit DC
voltage. DC
overvoltage trip limit is
420 V for 200 V drives
and 840 V for 400 V
drives.
Drive IGBT
temperature is
excessive. Fault trip
limit is 135 °C.
Short circuit in motor
cable(s) or motor
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.
Analog input AI1 signal
has fallen below limit
defined by parameter
3021 AI1 FAULT
LIMIT.
Analog input AI2 signal
has fallen below limit
defined by parameter
3022 AI2 FAULT
LIMIT.
WHAT TO DO
Check motor load.
Check acceleration time
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
Check that overvoltage controller is on
(parameter 2005 OVERVOLT
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.
Check ambient conditions. See also
section Derating on page 359.
Check air flow and fan operation.
Check motor power against drive
power.
Check motor and motor cable.
Check that undervoltage controller is
on (parameter 2006 UNDERVOLT
CTRL).
Check input power supply and fuses.
Check fault function parameter
settings.
Check for proper analog control signal
levels.
Check connections.
Check fault function parameter
settings.
Check for proper analog control signal
levels.
Check connections.
