The factory settings for the motor data can be edited with this parameter. The factory setting in
parameters P201...P209 is a 4-pole DS standard motor with the nominal FI power setting.
By selecting one of the possible digits and pressing the ENTER key, all motor parameters
(P201…P209) are adjusted to the selected standard power. The basis for the motor data is a 4-
pole DS standard motor.
0 = No change to data
1 = No motor: In this setting, the FI operates without current control, slip compensation and
pre-magnetising time, and is therefore not recommended for motor applications. Possible
applications are induction furnaces or other applications with coils and transformers. The

Note: As P200 returns to = 0 after the input confirmation, the control of the set motor can be
implemented via parameter P205.
P201 Nominal frequency P Always visible
20.0..00.3990.9 Hz
[

The motor nominal frequency determines the V/f break point at which the FI supplies the nominal
voltage (P204) at the output.
P202 Nominal speed P Always visible
300..0.24000 rpm
[

]
The nominal motor speed is important for the correct calculation and control of the motor slip and
the speed display (P001 = 1).
P203 Nominal current P Always visible
0.1..00.5400.0 A
[

]
The nominal motor current is a decisive parameter for the current vector control.
P204 Nominal voltage P Always visible
100..0.800 V
[

]
The >Nominal voltage< matches the mains voltage to the motor voltage. In combination with the
nominal frequency, this produces the voltage/frequency characteristic curve.
P205 Nominal power P Always visible
0.00... 315.00 kW
[

]
The motor nominal power controls the motor set via P200.
P206 cos 
P Always visible
0.50...0.90
[

The motor cos

is a decisive parameter for the current vector control.

These setting values depend on the selection in parameter P200.
