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 button on the BOP-2.
3. Via Digital Input 3 (default setting)
Possible Causes
Ø Motor power (P0307) does not
correspond to the inverter power
(r0206)
Ø
Motor lead short circuit
Ø
Earth faults
Ø DC-link voltage (r0026) exceeds
trip level (P2172)
Ø
Overvoltage can be caused
either by too high main supply
voltage or if motor is in
regenerative mode.
Ø
Regenerative mode can be
cause by fast ramp downs or if
the motor is driven from an
active load.
Ø
Main supply failed.
Ø
Shock load outside specified
limits.
Ø
Ventilation inadequate
Ø Ambient temperature is too high.
Ø Inverter overloaded.
Ø Duty cycle too demanding.
Ø Motor power (P0307) exceeds
inverter power capability (r0206).
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
Ø Increase the ramp time
Ø 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)
