Parameter Function
P0291[0...2] Inverter protection
Bit 00 for enabling/disabling automatic pulse frequency reduction at output frequencies below 2 Hz. The
benefit is to reduce the noises at frequencies below 2 Hz.

P0292 Inverter temperature
warning [°C]
Defines the temperature difference (in °C) between the overtemperature trip threshold (F4) and the warn-
ing threshold (A504) of the inverter. The trip threshold is stored internally by the inverter and cannot be
changed by the user.
P0294 Inverter I
Defines the [%] value at which warning A505 (inverter I
Inverter I
The I t calculation value is deemed = 100 % when this maximum tolerable period is reached.

Dependency:
The output current of the inverter has been reduced.
•
The value of I
•
Note: P0294 = 100 % corresponds to stationary nominal load.
P0295 Inverter fan off delay
time [s]
Defines inverter fan switch off delay time in seconds after inverter has stopped.
Note: Setting to 0, inverter fan will switch off when the inverter stops, that means no delay.
P0301[0...2] Easy motor data, rated
motor power [kW]
Rated motor power from the rating plate. No other data is necessary. If this parameter is used, the rest of
the motor data are then estimated by the firmware.
Dependency: Changeable only when P0010 = 1 (quick commissioning).
Caution: This functionality is only valid with 50 Hz supply, star configuration on 4-pole motors. You must set this
parameter to zero if you desire to set the other motor data.
