MICROMASTER 440
Operating Instructions (Compact)
(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
(Nominal motor current [A]
from rating plate)
(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.
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.
(Nominal motor efficiency in [%] from rating plate)
Setting 0 causes internal calculation of value.
P0100 = 0: P0309 no significance, no entry required.
Rated motor frequency
(Nominal motor frequency in [Hz] from rating plate)
Pole pair number recalculated automatically if parameter is changed.
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.
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
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 %.
