P205 Nominal motor power P
Setting range 0.00 … 250.00 kW
Factory setting
{See Note}
Description
The motor nominal power controls the motor set via P200.
Note
The default setting depends on the nominal power of the FI and the setting in P200.
P206 Motor cos phi S P
Setting range
0.50 … 0.95
Factory setting {See Note}
Description
The motor cos ϕ is a decisive parameter for current vector control.
Note
The default setting depends on the nominal power of the FI and the setting in P200.
P207 Motor circuit S P
Setting range
0 ... 1
Factory setting
{See Note}
Description
The motor circuit is decisive for stator resistance measurement (P220) and therefore
for current vector control.
Note The default setting depends on the nominal power of the FI and the setting in P200.

P208 Stator resistance S P
Setting range
0.00 … 300.00 Ω
Factory setting {See Note}
Description
Motor stator resistance

Resistance of a phase winding with a three-phase motor.
The stator resistance has a direct influence on the current control of the FI. A value
which is too high may result in overcurrent; a value which is too low may result in low
motor torque.
The result of the stator resistance measurement (see P220) is shown in P208.
However, this value can also be overwritten there.
Note
For optimum functioning of the current vector control, the stator resistance must be
measured automatically by the FI.
The default setting depends on the nominal power of the FI and the setting in P200.
