P0309
Rated motor efficiency
0.0 - 99.9
See table in
Chap. 6.4
%
Nominal motor efficiency in [%] from rating plate.
Dependency:
Setting 0 causes internal calculation of value.
P0310
Rated motor frequency
12.00 - 300.00
50.00
Hz
Nominal motor frequency [Hz] from rating plate.
Dependency:
Pole pair number recalculated automatically if parameter is changed.
P0311
Rated motor speed
0 - 40000
See table in
Chap. 6.4
1/min
Nominal motor speed [rpm] from rating plate.
Dependency:
● Setting 0 causes internal calculation of value.
● Slip compensation in V/f control requires rated motor speed for correct operation.
● Pole pair number recalculated automatically if parameter is changed.
● Required for vector control and V/f control with speed controller.
P0320
Motor magnetizing current
0.0 - 99.0
0.0
%
Defines motor magnetization current in [%] relative to P0305 (rated motor current).
P0335
Motor cooling
0 - 1
0
--
Selects motor cooling system used.
Possible settings:
0
Self-cooled: Using shaft mounted fan attached to motor
1
Forced-cooled: Using separately powered cooling fan
P0350
Stator resistance (line-to-line)
0.0001 - 2000.0
Depends on
inverter type
Ohm
Stator resistance value in [Ohms] for connected motor (from line-to-line). The parameter value includes the
cable resistance.
P0350 = 2 x (R
cable
+ R
s
)
There are two ways to determine the value for this parameter:
1. Measure using P1910 = 1 (motor data identification - value for stator resistance is overwritten).
2. Measure manually using an Ohmmeter.
Note:
Default value depends on inverter type.
