Rated Motor [ according to
Current the inverter
model ]
0.01A (<10.0A);
0.1A (>9.99A)
Rated motor current indicated on the motor nameplate.
It is the rms-value of the rated motor line current.
Set this parameter according to the motor nameplate data and the
connection digram in the terminal box.
This parameter is used in V/F control [slip compensation function
and automatic torque boost function(automatic IxR)] and vector
control.
P402 0...9999rpm
Rated Motor [ according to
Speed the inverter model
and market ]
1rpm
Set this parameter according to the motor nameplate data.
This parameter is used only in Vector Control mode.
This
parameter in only
available in Vector
Control (P202=2)

Rated Motor [ 50.00Hz or 60.00Hz
Frequency depending on
the market ]
0.01Hz (<100.0Hz);
0.1Hz (>99.99Hz)
This
parameter in only
available in Vector
Control (P202=2)
Set this parameter according to the motor nameplate data.
This parameter is used only in Vector Control mode.

Rated Motor [ according to the
Efficiency inverter model ]
0.1%
This
parameter is only
available in Vector
Control (P202=2)
Set this parameter according to motor nameplate.
If this data are not available:
- If the rated motor power factor is known
(cos =P407), determine the efficiency by the following equation:
where P is the motor power in HP, V is the rated motor
voltage in Volts (V) - P400, and I is the rated motor current in
ampere (A) - P401.
- For an approximation, use the values from the table of item 9.3.
It is used only in Vector Control Mode.

This
parameter in only
available in Vector
Control (P202=2)
Rated motor voltage indicated on the motor nameplate.
It is the rms-value of the motor line voltage.
Set this parameter according to the motor nameplate data and the
connection digram in the terminal box.
This parameter is used only in Vector Control Mode.
