Displays maximum output current of the variable speed drive.
Unit: A
Min: -
Def: -
Max: -
Level 3
P0304
Rated motor voltage
Nominal motor voltage [V] from rating plate. The following diagram shows a typical rating plate
with the locations of the relevant motor data.
Unit: V
Min: 10
Def: 230
Max: 2000
Level 1
Dependency:
Changeable only when P0010=1 (quick commissioning).
P0305
Rated motor current
Nominal motor current [A] from rating plate.
Unit: A
Min: 0.01
Def: 3.25
Max: 10000.00
Level 1
Dependency:
Changeable only when P0010=1 (quick commissioning).
Depends also on P0320 (motor magnetization current).
Note:
For asynchronous motors, the maximum value is defined as the maximum variable speed drive current (r0209).
For synchronous motors, the maximum value is defined as twice the maximum variable speed drive current (r0209).
The minimum value is defined as 1/32 times variable speed drive rated current (r0207).
P0307
Rated motor power
Nominal motor power [kW/hp] from rating plate.
Unit: -
Min: 0.01
Def: 0.75
Max: 2000.00
Level 1
Dependency:
If P0100=1 ([kW],frequency default 50 Hz), values will be in [hp].
Changeable only when P0010=1 (quick commissioning).
P0308
Rated motor cosPhi
Nominal motor power factor (cosPhi) from rating plate.
Unit: -
Min: 0.000
Def: 0.000
Max: 1.000
Level 3
Dependency:
Changeable only when P0010=1 (quick commissioning).
Visible only when P0100=0 or 2, (motor power entered in [kW]).
Setting 0 causes internal calculation of value (see r0332).
P0309
Rated motor efficiency
Nominal motor efficiency in [%] from rating plate.
Unit: %
Min: 0.0
Def: 0.0
Max: 99.9
Level 3
Dependency:
Changeable only when P0010=1 (quick commissioning).
Visible only when P0100=1, (i.e. motor power entered in [hp]).
Setting 0 causes internal calculation of value (see r0332).
Note:
P0309=100 % corresponds to superconducting
P0310
Rated motor frequency
Nominal motor frequency [Hz] from rating plate.
Unit: Hz
Min: 12.00
Def: 50.00
Max: 650.00
Level 1
Dependency:
Changeable only when P0010=1 (quick commissioning).

P0311
Rated motor speed
Nominal motor speed [rpm] from rating plate.
Unit: 1/min
Min: 0
Def: 0
Max: 40000
Level 1
Dependency:
Changeable only when P0010=1 (quick commissioning).
Setting 0 causes an internal calculation of value.
Required for V/f control with speed controller.
Slip compensation in V/f control requires the rated motor speed for correct operation.
The pole pair number is recalculated automatically if the parameter is changed.
r0313
