P204 Nominal
voltage
S
P
100 ... 800 V
[
]
The >Nominal voltage< matches the mains voltage to the motor voltage. In combination with the
nominal frequency, the voltage/frequency characteristic curve is produced.
P205 Nominal
output
P
0.00 ... 150.00 kW
[***]
The motor nominal power controls the motor set via P200.
P206
Cos
S
P
0.50 ... 0.90
[***]
The motor cos
is a decisive parameter for the current vector control.
P207 Motor
circuit
S
P
0 ... 1
[***]
0 =
Star
1 =
Delta
The motor circuit is decisive for stator resistance measurement (P220) and therefore for current
vector control.
P208 Stator
resistance
S
P
0.00 ... 300.00
[***]
Motor stator resistance
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
S
P
0.1 ... 300.0 A
[***]
This value is always calculated automatically from the motor data if there is a change in the
parameter >cos
< 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
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.
P211
1
Dynamic boost
S
P
0 ... 150 %
[ 100 ]
The dynamic boost affects the torque generating current and is therefore a load-dependent
parameter. The factory 100% setting is also sufficient for typical applications.
Too high a value can lead to overcurrent in the FI. Under load therefore, the output voltage will
be raised too sharply. Too low a value will lead to insufficient torque.
These settings are dependent on the nominal power of the FI or the selection in parameter P200.
