Fault
Code
No. Description Corrective Action
Stop 0x00 Drive is READY and in a stopped condition. The motor is not energized. No enable
signal is present to start the drive
P-def 0X0A Factory Default parameters
have been loaded Press the STOP key, drive is ready to configure for
particular application
F0001 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 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
F0009 0x04 Motor thermal overload
protection trip. The drive
has tripped after delivering
>100% of value in
9906 for
a period of time to prevent
damage to the motor.
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
OI-b 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
OL-br 0x02 Brake resistor thermal
overload. The drive has
tripped to prevent damage
to the brake resistor 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
nd
deceleration time (parameter 2206 ). 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
. Use an external thermal protection device for the
brake resistor. In this case, parameter
2020 may be
set to 2
F0004 ECT 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.
