Code
(hex)
Check motor and motor cable for
cabling errors.
Short-circuit in motor
cable(s) or motor.
Short circuitA2B4
Check motor and motor cable (in-
cluding phasing and delta/star
connection).
Short circuit in the upper
transistor of the U-phase.
Short circuit in the lower
transistor of the U-phase.
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.
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
correction capacitors or surge ab-
sorbers in motor cable.
Short circuit in the upper
transistor of the WU-
phase.
For frames R6 to R8, check the aux-
iliary code.
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.
Check motor cable, ambient condi-
tions, air flow and fan operation,
heatsink fins for dust pick-up, mo-
tor power against drive power.
Excessive IGBT junction to
case temperature.
IGBT overloadA2BA
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.
Intermediate circuit DC
voltage too high.
DC link over-
voltage
A3A1
Check the supply voltage setting
and fuses.
Intermediate circuit DC
voltage too low (when the
drive is stopped).
DC link under-
voltage
A3A2
Check the supply voltage and sup-
ply voltage setting.
The voltage of the interme-
diate DC circuit has not
rose to operating level.
