Corrective Action
Press the STOP key, drive is ready to configure for particular application
Fault occurs immediately on drive enable or run command
Check the output wiring connections to the motor and the motor for short circuits phase to
phase and phase to earth.
Fault occurs during motor starting
Check the motor is free to rotate and there are no mechanical blockages. If the motor has a
brake fitted, check the brake is releasing correctly. Check for correct star-delta motor wiring.
Ensure the motor nameplate current is correctly entered in parameter 9906. Increase
acceleration time in parameter 2202. Reduce motor boost voltage setting in parameter 2603
Fault occurs when motor operating at constant speed Investigate overload.
Fault occurs during motor acceleration or deceleration
The accel/decel times are too short requiring too much power. If parameter 2202 or 2203
cannot be increased, a bigger drive may be required
Ensure the correct motor nameplate current value is entered in parameter 9906. Check for
correct Star or Delta wiring configuration. Check to see when the decimal points are flashing
(which indicates the output current > parameter 9906 value) and either increase acceleration
ramp (parameter 2202) or decrease motor load. Check the total motor cable length is within
the drive specification. Check the load mechanically to ensure it is free, and that no jams,
blockages or other mechanical faults exist
Check the cabling to the brake resistor and the brake resistor for short circuits or damage.
Ensure the resistance of the brake resistor is equal to or greater than the minimum value for the
relevant drive shown in the table in section 12.2
Only occurs if parameter 2020 = 1. The internal software protection for the brake resistor has
activated to prevent damage to the brake resistor.
Increase the deceleration time (parameter 2203) or 2
Reduce the load inertia
For Other Brake Resistors
Ensure the resistance of the brake resistor is equal to or greater than the minimum value for the
relevant drive shown in the table in section 12.2. Use an external thermal protection device for
the brake resistor. In this case, parameter 2020 may be set to 2
Check the wiring to motor and the motor for phase to phase and phase to earth short circuits.
Disconnect the motor and motor cable and retest. If the drive trips with no motor connected, it
must be replaced and the system fully checked and retested before a replacement unit is
installed.
Check the supply voltage is within the allowed tolerance for the drive. If the fault occurs on
deceleration or stopping, increase the deceleration time in parameter 2203 or install a suitable
brake resistor and activate the dynamic braking function with parameter 2020
The incoming supply voltage is too low. This trip occurs routinely when power is removed from
the drive. If it occurs during running, check the incoming power supply voltage and all
components in the power feed line to the drive.
The drive is too hot. Check the ambient temperature around the drive is within the drive
specification. Ensure sufficient cooling air is free to circulate around the drive.
Increase the panel ventilation if required. Ensure sufficient cooling air can enter the drive, and
that the bottom entry and top exit vents are not blocked or obstructed.
Trip occurs when ambient temperature is less than -10°C. The temperature must be raised over
-10°C in order to start the drive.
Refer to your local ABB representative
Drive ambient temperature too high, check adequate cooling air is provided
E-trip requested on control input terminals. Some settings of parameter 9902 DIGITAL INPUTS
FUNCTION SELECT require a normally closed contactor to provide an external means of tripping
the drive in the event that an external device develops a fault. If a motor thermistor is
connected check if the motor is too hot.
Check communication link between drive and external devices. Make sure each drive in the
network has its unique address.
Drive intended for use with a 3 phase supply has lost one input phase.
Spin start function failed to detect the motor speed.
Parameters not saved, defaults reloaded.
Try again. If problem recurs, refer to your local ABB representative
Check input current in range defined by parameter 1300.

Measured motor stator resistance varies between phases. Ensure the motor is correctly
connected and free from faults. Check the windings for correct resistance and balance.
Measured motor stator resistance is too large. Ensure the motor is correctly connected and free
from faults. Check that the power rating corresponds to the power rating of the connected
drive.
Measured motor inductance is too low. Ensure the motor is correctly connected and free from
faults.
Measured motor inductance is too large. Ensure the motor is correctly connected and free from
faults. Check that the power rating corresponds to the power rating of the connected drive.
Measured motor parameters are not convergent. Ensure the motor is correctly connected and
free from faults. Check that the power rating corresponds to the power rating of the drive.
