P205
Nominal power
(Nominal motor power output)
P
0.00 ... 250.00 kW
The motor nominal power controls the motor set via P200.
P206
Cos phi
(Motor cos
j
)
S
P
0.50 ... 0.90
{
***
}
The motor cos
j is a decisive parameter for the current vector control.

}
0 = Star
1 = Delta
The motor circuit is decisive for stator resistance measurement (P220) and therefore for current
vector control.

Stator resistance
(Stator resistance)

P
0.00 ... 300.00 W

Motor stator resistance
Þ resistance of a phase winding with a DC motor.
Has a direct influence on the current control of the FI. Too high a value will lead to a possible
overcurrent; too low a value to a motor torque that is too low.
The parameter P220 can be used for simple measurement. Parameter P208 can be used for
manual setting or as information about the result of an automatic measurement.
NOTE:
For optimum functioning of the current vector control, the stator resistance must be automatically
measured by the FI.

P209
No load current
(No load current)
S
P
0.1 ... 1000.0 A
{

}
This value is always calculated automatically from the motor data if there is a change in the
parameter >cos
j< P206 and the parameter >Nominal current< P203.
NOTE:
If the value is to be entered directly, then it must be set as the last motor data. This is
the only way to ensure that the value will not be overwritten.

P210
Static boost
(Static boost)
S
P
0 ... 400 %
{ 100 }
The static boost affects the current that generates the magnetic field. This is equivalent to the no
load current of the respective motor and is therefore load-independent. The no load current is
calculated using the motor data. The factory setting of 100% is sufficient for normal applications.
