Warning/Aux code (aux code
visible only on assistant control
panel and drive composer)
Cause What to do
64FF Fault reset A fault has been reset. Event. Informative only.
A2B1 Overcurrent Output current exceeded
internal fault limit.
Check motor load, acceleration
times, earth fault in motor or motor
cables, contactors opening and
closing, start-up data, power factor
correction in capacitors or surge
absorbers in motor cable.
A2B3 Earth leakage Load unbalance typically due to
earth fault in motor or motor
cable.
Check for no power factor
correction capacitors or surge
absorbers in motor cable, and no
earth fault in motor or motor cables.
A2B4 Short circuit Short-circuit in motor cable(s) or
motor.
Check motor and motor cable for
cabling errors, no earth fault in
motor or motor cables, no power
factor correction capacitors or surge
absorbers in motor cable.
A2BA IGBT overload Excessive IGBT junction to case
temperature.
Check motor cable, ambient
conditions, air flow and fan
operation, heatsink fins for dust
pick-up, motor power against drive
power.
A3A1 DC link overvoltage Intermediate circuit DC voltage
too high.
Check Overvoltage control
parameter, no static or transient
overvoltage in mains voltage, brake
chopper/resistor, and deceleration
time. Use coast-to-stop. Retrofit
drive with chopper and resistor.
A3A2 DC link undervoltage Intermediate circuit DC voltage
too low (when the drive is
stopped).
Check the supply voltage setting
and fuses.
A3AA DC not charged The voltage of the intermediate
DC circuit has not rose to
operating level.
Check the supply voltage and
supply voltage setting.
A490 Incorrect temperature sensor
setup
Sensor type mismatch Check the temperature setting
parameters.
A491 External temperature 1 Measured temperature 1
exceeded warning limit.
Check the parameter 35.02
Measured temperature 1, cooling of
the motor, value of 35.13
Temperature 1 warning limit.
A492 External temperature 2 Measured temperature 2
exceeded warning limit.
Check the parameter 35.03
Measured temperature 2, cooling of
the motor, value of 35.23
Temperature 2 warning limit.
A4A0 Control board temperature. Control board temperature is
excessive.
1 – Sensor fault.
Check the sensor and change the
control board.
