P0304 =... P0304 =... Rated motor voltage
(Nominal motor voltage [V]
from rating plate)
The rated motor voltage on the rating
plate must be checked, regarding the
star/delta circuit configuration to
ensure that it matches with the circuit
connection configured at the motor
terminal board
P0305 =... P0305 =... Rated motor current
(Nominal motor current [A]
from rating plate)
P0307 =... P0307 =... Rated motor power
(Nominal motor power [kW/hp]
from rating plate)
If P0100 = 0 or 2, value will be in kW.
If P0100 = 1, value will be in in hp.

Example of a typical motor rating plate
(data for a delta circuit configuration).
P0308 =... P0308 =... Rated motor cosPhi
(Nominal motor power factor (cos
ϕ) from rating plate)
If the setting is 0, the value is automatically calculated
P0100 = 1,2: P0308 no significance, no entry required.
P0309 =... P0309 =... Rated motor efficiency
(Nominal motor efficiency in [%] from rating plate)
Setting 0 causes internal calculation of value.
P0100 = 0: P0309 no significance, no entry required.
P0310 =... Rated motor frequency
(Nominal motor frequency in [Hz] from rating plate)
Pole pair number recalculated automatically if parameter is changed.
P0311 =... Rated motor speed
(Nominal motor speed in [rpm] from rating plate)
Setting 0 causes internal calculation of value.
NOTE
An entry must be made for closed-loop Vector control, V/f control with FCC and
for slip compensation.
Motor magnetizing current
(this is entered as a % referred to P0305)
Motor magnetizing current as a % relative to P0305 (rated motor current).
With P0320 = 0, the motor magnetizing current is calculated using P0340 = 1 or
using P3900 = 1 - 3 (end of the quick commissioning) – and is displayed in
parameter r0331.
P0335 =... Motor cooling
(Selects motor cooling system used)
0 Self-cooled: Using shaft mounted fan attached to motor
1 Force-cooled: Using separately powered cooling fan
2 Self-cooled and internal fan
3 Force-cooled and internal fan
P0640 =... Motor overload factor
(Motor overload factor in [%] relative to P0305)
This defines the limit of the maximum output current as a % of the rated motor
current (P0305). This parameter is set, using P0205 for constant torque, to
150 %, and for variable torque, to 110 %.
P0700 =... Selection of command source
(enters the command source)
0 Factory default setting
1 BOP (keypad)
2 Terminal
4 USS on BOP link
5 USS on COM link (control terminals 29 and 30)
6 CB on COM link (CB = communications module)
