(hex)
Measure insulation resistances of motor
cables and motor.
Contact your local ABB representative.
Check AC fuses.IGBT supply unit has detected an earth
fault.
Earth leakage2E01
Check for earth leakages.
Check supply cabling.
Check power modules.
Check there are no power factor
correction capacitors or surge absorbers
in supply cable.
If no earth fault can be detected, contact
your local ABB representative.
Check that the speed points of the curve
(defined by 29.70…29.79) are in
increasing order.
Parametrization of the speed/torque
limitation curve (in the DC voltage
reference chain) are inconsistent.

1. The drive hardware is supplied from
a common DC bus.

cable is connected to the motor
connection).
3. Check there are no power factor
correction capacitors or surge
absorbers in motor cable.
3. Drive has detected load unbalance
typically due to earth fault in motor
or motor cable.
Check for an earth fault in motor or
motor cables by measuring the
insulation resistances of motor and
motor cable.
Try running the motor in scalar
control mode if allowed. (See
parameter 99.4 Motor control
mode.)
Check that overvoltage control is on
(parameter 30.30 Overvoltage control).

Check that the supply voltage matches
the nominal input voltage of the drive.
Check the supply line for static or
transient overvoltage.
Check brake chopper and resistor (if
present).
Check deceleration time.
Use coast-to-stop function (if applicable).
Retrofit drive with brake chopper and
brake resistor.
With parallel-connected modules, check
the auxiliary code (format XXXY YYZZ).
