15.1. Fault messages
Fault Code No. OLED Message Description Corrective Action
 00 No Fault No Fault Displayed in P0-13 if no faults are recorded in the log
 03 Over current trip Instantaneous over current on
drive output.
Fault Occurs on Drive Enable
Check the motor and motor connection cable for phase – phase and phase –
earth short circuits.
Check the load mechanically for a jam, blockage or stalled condition
Ensure the motor nameplate parameters are correctly entered, P1-07, P1-
08, P1-09.
Reduced the Boost voltage setting in P1-11
Increase the ramp up time in P1-03
If the connected motor has a holding brake, ensure the brake is correctly
connected and controlled, and is releasing correctly
. 04 Over load trip Drive has tripped on overload
after delivering >100% of
value in P1-08 for a period of
time. Check to see when the decimal points are flashing (drive in overload) and
either increase acceleration rate or reduce the load.
Check motor cable length is within the limit specified for the relevant drive
in section 13.4
Ensure the motor nameplate parameters are correctly entered in P1-07, P1-
08, and P1-09
Check the load mechanically to ensure it is free, and that no jams, blockages
or other mechanical faults exist

 06 Over voltage Over voltage on DC bus The value of the DC Bus Voltage can be displayed in P0-20
A historical log is stored at 256ms intervals prior to a trip in parameter P0-36
This fault is generally caused by excessive regenerative energy being
transferred from the load back to the drive. When a high inertia or over
hauling type load is connected.
If the fault occurs on stopping or during deceleration, increase the
deceleration ramp time P1-04.
If operating in PID control, ensure that ramps are active by reducing P3-11
 07 Under voltage Under voltage on DC bus This occurs routinely when power is switched off.
If it occurs during running, check the incoming supply voltage, and all
connections into the drive, fuses, contactors etc.
 08 Over temperature trip Heatsink over temperature The heatsink temperature can be displayed in P0-21.
A historical log is stored at 30 second intervals prior to a trip in P0-38
Check the drive ambient temperature
Ensure the drive internal cooling fan is operating
Ensure that the required space around the drive as shown in section 3.8 thru
3.10 has been observed, and that the cooling airflow path to and from the
drive is not restricted
Reduce the effective switching frequency setting in parameter P2-24
Reduce the load on the motor / drive
 09 Under temperature trip Drive Under temperature Trip occurs when ambient temperature is less than -10°C. The temperature
must be raised over -10°C in order to start the drive.

have been loaded Press STOP key, the drive is now ready to be configured for the required
application. Four button defaults – see section 5.8
 11 External trip Digital Input External trip E-trip requested on control input terminals. Some settings of P1-13 require a
normally closed contact 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.
 12 Optibus serial comms
fault
Communications Fault Communications lost with PC or remote keypad. Check the cables and
connections to external devices
 13 Excessive DC ripple Excessive DC Ripple on
Internal DC bus The DC Bus Ripple Voltage level can be displayed in parameter P0-16
A historical log is stored at 20ms intervals prior to a trip in parameter P0-37
Check all three supply phases are present and within the 3% supply voltage
level imbalance tolerance.
Reduce the motor load
If the fault persists, contact your local Drives Sales Partner
 14 Input phase loss Input phase missing trip Drive intended for use with a 3 phase supply, one input phase has been
disconnected or lost.
 15 Instant over current Instantaneous over current on
drive output. Refer to fault 3 above
 16 Thermistor Fault Faulty thermistor on heat-sink. Refer to your drive Sales Partner.

Internal memory fault. Parameters not saved, factory defaults are reloaded.
If problem reoccurs, refer to your Authorised Distributor.

4-20mA Signal Lost The reference signal on Analog Input 1 or 2 (Terminals 6 or 10) has dropped
below the minimum threshold of 3mA when signal format is set to 4-20mA.
Check the signal source and wiring to the drive terminals.
