Fault Code No. OLED Message
Description
Corrective Action
inhibi
- Inhibit
Safety inputs not activated
Stop
00
stop
No Fault
Displayed in P0-13 if no faults are recorded in the log
OI-b
01
Brake channel over
current
Too large brake
resistor current
Ensure the connected brake resistor is above the minimum permissible
level for the drive. Check the brake resistor and wiring for possible short
circuits.
OL-BR
02
Brake resistor
overload
Too large power to
brake resistor
Brake resistor is overloaded and trips to protect the resistor. Ensure the
brake resistor is being operated within its designed parameter before
making any parameter or system changes.
To reduce the load on the resistor, increase deceleration the time, reduce
the load inertia or add further brake resistors in parallel, observing the
minimum resistance value for the drive in use.
O-I
03 Over current trip
Instantaneous over
current on drive
output.
Excess load on the
motor.
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. If operating in Vector mode (P4-01 – 0 or 1), also check the
motor power factor in P4-05 and ensure an autotune has been successfully
completed for the connected motor.
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
Fault Occurs When Running
If operating in Vector mode (P4-01 – 0 or 1), reduce the speed loop gain in
P4-03.
I_trP
04 Overload 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.
Ensure the motor nameplate parameters are correctly in P1-07, P1-08, P1-
09.
If operating in Vector mode (P4-01 – 0 or 1), also check the motor power
factor in P4-05 and ensure an autotune has been successfully completed for
the connected motor.
Check the load mechanically to ensure no jams, blockages or other
mechanical faults exist.

Hardware Enable
Circuit Error
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.
O-Uolt
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 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 or connect a suitable brake resistor to the
drive.
If operating in Vector Mode, reduce the speed loop gain P4-03
If operating in PID control, ensure that ramps are active by reducing P3-11
U-Uolt
07 Under voltage
Under voltage on DC
bus
Occurs routinely when power is switched off. If occurs during running,
check the incoming supply voltage, all connections into the drive, fuses,
contactors etc.
O-t
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 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.
U-t
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.
