P0292
Converter temperature
warning [°C]
0 - 25 5 U, T - - U16 3
Defines the temperature difference (in °C) between the overtemperature trip threshold (F4) and the warn-
ing threshold (A504) of the converter. The trip threshold is stored internally by the converter and cannot be
changed by the user.
P0294
Converter I

t warning [%]
10.0 - 100.0
95.0
U, T
-
-
Float
3
Defines the [%] value at which warning A505 (converter I
2
t) is generated.
Converter I
2
t calculation is used to determine a maximum tolerable period for converter overload.
The I
2
t calculation value is deemed = 100 % when this maximum tolerable period is reached.
Dependency:
• The output current of the converter has been reduced.
• The value of I
2
t does not exceed 100 %.
Note:
P0294 = 100 % corresponds to stationary nominal load.
P0295
Converter fan off delay time
[s]
0 - 3600 0 U, T - - U16 3
Defines converter fan switch-off delay time in seconds after converter has stopped.
Note:
Setting to 0, converter fan will switch off when the converter stops, that means no delay.
P0301[0...2]
Easy motor data, rated
motor power [kW]
0 - 2000 0 C(1) - DDS Float 1
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.
P0304[0...2]
Rated motor voltage [V]
10 - 2000
400
C(1)
-
DDS
U16
1
Nominal motor voltage from rating plate.
Dependency:
Changeable only when P0010 = 1 (quick commissioning).
Default value is depending on converter type and its rating data.
Caution:
The input of rating plate data must correspond with the wiring of the motor (star/delta). This means, if delta
wiring is used for the motor, delta rating plate data has to be entered.
