 0x00 Drive is healthy and in a stopped condition. The motor is not energised. No enable signal is present to start the drive

0x03
Instantaneous Over current
on the drive output.
Excess load or shock load on
the motor. 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 the correct star-delta motor
wiring. Ensure the motor nameplate current is correctly entered in P-08. Increase the
acceleration time in P-03. Reduce the motor boost voltage setting in P-11
Fault occurs when motor operating at constant speed
Investigate overload or malfunction.
Fault occurs during motor acceleration or deceleration
The accel/decel times are too short requiring too much power. If P-03 or P-04 cannot be
increased, a bigger drive may be required
.  0x04
Motor thermal overload
protection trip. The drive has
tripped after delivering
>100% of value in P-08 for a
period of time to prevent
damage to the motor. Ensure the correct motor nameplate current value is entered in P-08. Check for correct Star
or Delta wiring configuration. Check to see when the decimal points are flashing (which
indicates the output current > P-08 value) and either increase acceleration ramp (P-03) 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
 0x01
Brake channel over current
(excessive current in the
brake resistor) 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 10.2
 0x02
Brake resistor thermal
overload. The drive has
tripped to prevent damage
to the brake resistor Only occurs if P-34 = 1. The internal software protection for the brake resistor has activated
to prevent damage to the brake resistor.
If the standard option braking resistor is being used, P-34 MUST be 1
Increase the deceleration time (P-04) or 2
nd deceleration time (P-24). 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 10.2. Use an external thermal protection
device for the brake resistor. In this case, P-34 may be set to 2
 0x05
Hardware Over Current 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.
. 0x06
Over voltage on DC bus 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 P-04 or install a suitable brake
resistor and activate the dynamic braking function with P-34
. 0x07
Under voltage on DC bus 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.
 0x08
Heatsink over temperature 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.
 0x09
Under temperature Trip occurs when ambient temperature is less than -10°C. Temperature must be raised over
-10°C in order to start the drive.

 0x0B
External trip
(on digital Input 3) E-trip requested on digital input 3. Normally closed contact has opened for some reason. If
motor thermistor is connected check if the motor is too hot.

network has its unique address.
