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 %.
