A2B4 Short circuit
EN
HI
A2BA IGBT overload
A3A1 DC link over-
voltage
A3A2 DC link under-
voltage
A3AA DC not charged
Cause
Short-circuit in motor
cable(s) or motor.
Short circuit in the upper
transistor of the U-phase.
Short circuit in the lower
transistor of the U-phase.
Short circuit in the upper
transistor of the V-phase.
Short circuit in the lower
transistor of the V-phase. Check there are no power factor
Short circuit in the upper
transistor of the WU-
phase.
Short circuit in the lower
transistor of the W-phase.
DC capacitor short circuit.
State feedback from out-
put phases does not
match control signals.
For frames R6 and R7.
Excessive IGBT junction to
case temperature.
Intermediate circuit DC
voltage too high.
Intermediate circuit DC
voltage too low (when the
drive is stopped).
The voltage of the interme-
diate DC circuit has not
rose to operating level.
What to do
Check motor and motor cable for
cabling errors.
Check motor and motor cable (in-
cluding phasing and delta/star
connection).
Check for an earth fault in motor or
motor cables by measuring the in-
sulation resistances of motor and
motor cable. See chapter Electrical
installation , section Checking the
insulation of the assembly in the
Hardware manual of the drive.
correction capacitors or surge ab-
sorbers in motor cable.
For frames R6 to R8, check the aux-
iliary code.
Check motor cable, ambient condi-
tions, air flow and fan operation,
heatsink fins for dust pick-up, mo-
tor power against drive power.
Check Overvoltage control paramet-
er, no static or transient over-
voltage in mains voltage, brake
chopper/resistor, and deceleration
time. Use coast-to-stop. Retrofit
drive with chopper and resistor.
Check the supply voltage setting
and fuses.
Check the supply voltage and sup-
ply voltage setting.
