Fault tracing
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 (2202
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 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.
Check ambient conditions. See also section
on page 291.
Check air flow and fan operation.
Check motor power against unit 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.
