Ø  Motor power (P0307) does not

correspond to the inverter power
(r0206)

Ø  Motor lead short circuit
Ø Earth 

faults

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.  Motor must not be obstructed or overloaded.

Ø Increase 

the 

ramp 

time

Ø  Reduce the boost level

OFF2

Ø  Overvoltage can be caused either

by too high main supply voltage
or if motor is in regenerative
mode.

Ø  Regenerative mode can be

caused by fast ramp downs or if
the motor is driven from an active
load.

Check the following:

1.  Supply voltage (P0210) must lie within limits

indicated on the inverter rating plate.

2.  DC-link voltage controller must be enabled

(P1240) and parameterized properly.

3.  Ramp-down time (P1121) must match inertia

of load.

NOTE

Higher inertia requires longer ramp times

OFF2

Ø Main 

supply 

failed.

Ø  Shock load outside specified

limits.

Check the following:

1.  Supply voltage (P0210) must lie within limits

indicated on the inverter rating plate.

2.  Supply must not be susceptible to temporary

failures or voltage reductions.

OFF2

Ø Ventilation 

inadequate

Ø  Ambient temperature is too high.

Check the following:

1.  Pulse frequency must be set to default value

2.  Ambient temperature could be higher than

specified for the inverter

OFF2

Ø Inverter 

overloaded.

Ø  Duty cycle too demanding.
Ø  Motor power (P0307) exceeds

inverter power capability ( r0206).

Check the following:

1.  Load duty cycle must lie within specified

limits.

2.  Motor power (P0307) must match inverter

power (r0206)

OFF2

Motor overloaded

Check the following:

1.  Load duty cycle must be correct

2.  Motor temperatur warning level  (P0604) must

match.

OFF1

Stator resistance measurement
failure

Ø  Check if the motor is connected to the

inverter.

Ø  Check that the motor data have been entered

correctly.

OFF2

Read or write failure while saving
non-volatile parameter.

Factory Reset and new parameterization

Change drive

OFF2

Read failure for power stack
information or invalid data.

Change drive
