Description
No Fault Displayed in P0-13 if no faults are recorded in the log.
Brake channel over Ensure the connected brake resistor is above the minimum permissible level for the drive – refer to
current the ratings shown in section 10.2.
Check the brake resistor and wiring for possible short circuits.
Brake resistor overload The drive software has determined that the brake resistor is overloaded, and trips to protect the
resistor. Always 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.
Fault Occurs on Drive Enable
Over current trip
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 P1-1 1.
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.
Drive has tripped Check to see when the decimal points are flashing (drive in overload) and either increase
on overload after acceleration rate or reduce the load.

period of time.
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 it is free, and that no jams, blockages or other mechanical
faults exist.
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.
Over voltage on DC The value of the DC Bus Voltage can be displayed in P0-20.
bus
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 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 P3-1 1.
Under voltage on DC This occurs routinely when power is switched off.
bus
If it occurs during running, check the incoming supply voltage, and all connections into the drive,
fuses, contactors etc.
Heatsink over The heatsink temperature can be displayed in P0-21.
temperature
A historical log is stored at 30 second intervals prior to a trip in parameter 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 sections 3.5 to 3.9 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.
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.
Factory Default Press STOP key, the drive is now ready to be configured for the required application.

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.
