With this parameter the default setting of the motor data can be changed. Factory settings
(P201...P209) presume a 4-pole, three-phase standard motor and rated output of the frequency
inverter.
Selection of any of the optional numbers followed by operation of the ENTER key ensures that the
program will pre-set all of the motor parameters mentioned below (P201...P209). All of the motor
data refer to 4-pole, three-phase standard motors.
0 = no change of default
1 = no motor: This setting implies that the inverter will operate without current control, slip
compensation and biasing period, which means that while no motor should indeed be
connected, inverter performance will be sufficient for the control of induction furnaces or
other appllications involving coils or transformers. By setting the value to 1, a simulated
mains operation can be parameterised for which the following data are preset: 50.0Hz /
1500rpm / 15.0A / 400V / 0.00kW / cos =0.90 / star / R

acknowledgement P200 will return to option 0).
P201
Nominal frequency
P
Always available
20.0...399.9 Hz
[ ]
The nominal frequency of the motor determines the voltage-to-frequency break point at
which the FI will be supplying the nominal voltage (P204) at its output.
P202
Nominal speed
P
Always available
300...24000 rpm
[ ]
The nominal speed is essential information to enable motor slippage and speed indication (P001 =
1) to be properly calculated and corrected.
P203
Nominal current
P
Always available
0.1...540.0 A
[ ]
The nominal motor current is a crucial quantity with regard to vectorial current control.
P204
Nominal voltage
P
Always available
100...800 V
[ ]
With the >Nominal voltage< parameter setting the mains voltage is adjusted to the motor voltage.
On the basis of this setting and that of the nominal frequency the system will determine the volt-
age-to-frequency characteristic.
P205
Nominal power
P
Always available
0.00... 315.00 kW
[ ]
The nominal power parameter can be activated to verify the power of the motor set in P200.
The motor option set in parameter P200 determines the setting values of these parameters.
