Fault messages

In the event of a failure, the inverter switches off and a fault code appears on the
display.
NOTE
To reset the fault code, one of three methods listed below can be used:
1. Cycle the power to the drive.
2. Press the
3. Via Digital Input 3 (default setting)
Fault Possible Causes
Motor power (P0307) does not

correspond to the inverter power
OverCurrent
(r0206)
Motor lead short circuit
Earth faults
DC-link voltage (r0026) exceeds
F0002
trip level (P2172)
OverVoltage
Overvoltage can be caused
either by too high main supply
voltage or if motor is in
regenerative mode.
Regenerative mode can be
cause by fast ramp downs or if
the motor is driven from an
active load.
Main supply failed.

Diagnose & Remedy
Check the following:
1. Motor power (P0307) must correspond to inverter
power (r0206).
2. Cable length limits must not be exceeded.
3. Motor cable and motor must have no short-
circuits or earth faults
4. Motor parameters must match the motor in use
5. Value of stator resistance (P0350) must be
correct
6. Motor must not be obstructed or overloaded
Increase the ramp time
Reduce the boost level
Check the following:
1. Supply voltage (P0210) must lie within limits
indicated on rating plate .
2. DC-link voltage controller must be enabled
(P1240) and parameterized properly.
3. Ramp-down time (P1121) must match inertia of
load.
4. Required braking power must lie within specified
limits.
NOTE
Higher inertia requires longer ramp times; otherwise,
apply braking resistor.
Check the following:
1. Supply voltage (P0210) must lie within limits
indicated on rating plate.
2. Supply must not be susceptible to temporary
failures or voltage reductions.
Check the following:
1. Fan must turn when inverter is running
2. Pulse frequency must be set to default value
3. Ambient temperature could be higher than
specified for the inverter
Check the following:
1. Load duty cycle must lie within specified limits.
2. Motor power (P0307) must match inverter power
(r0206)
