CAUSE
Output current has exceeded trip
level.
Overcurrent trip limit for drive is
325% of drive nominal current.
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.
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.
Motor is operating in stall region
due to, for example, excessive
load or insufficient motor power.
WHAT TO DO
Check motor load.
Check acceleration time (parameters
ACCELER TIME 1 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
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
DECELER TIME 1 and 2206
Check input power line for static or transient
overvoltage.
Retrofit frequency converter with brake chopper and
brake resistor.
Check ambient conditions. See also section
on page 138.
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 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.
Check motor load and drive ratings.
Check fault function parameter settings.
