P0309[0...2]
Rated motor efficiency [%]
0.0 - 99.9
0.0
C(1)
-
DDS
Float
1
Nominal motor efficiency from rating plate.
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. The value is displayed in r0332.
P0310[0...2]
Rated motor frequency [Hz]
12.00 - 550.00
50.00
C(1)
-
DDS
Float
1
Nominal motor frequency from rating plate.
Dependency:
Changeable only when P0010 = 1 (quick commissioning).
Pole pair number recalculated automatically if parameter is changed.
Note:
Changes to P0310 can influence the maximum motor frequency. For further information see P1082.
P0311[0...2]
Rated motor speed [RPM]
0 - 40000
1395
C(1)
-
DDS
U16
1
Nominal motor speed from rating plate.
Dependency:
Changeable only when P0010 = 1 (quick commissioning).
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.
Note:
Default value is depending on converter type and its rating data.
r0313[0...2]
Motor pole pairs

-
-
DDS
U16
3
Displays number of motor pole pairs that the converter is currently using for internal calculations.
Dependency:
Recalculated automatically when P0310 (rated motor frequency) or P0311 (rated motor speed) is
changed.
r0313 = 1: 2-pole motor
r0313 = 2: 4-pole motor
...
P0314[0...2]
Motor pole pair number
0 - 99
0
C(1)
-
DDS
U16
3
Specifies number of pole pairs of motor.
Dependency:
Changeable only when P0010 = 1 (quick commissioning).
Setting 0 causes r0313 (calculated motor pole pairs) to be used during operation. Setting to > 0 overrides
r0313.
P0314 = 1: 2-pole motor
P0314 = 2: 4-pole motor
...
P0320[0...2]
Motor magnetizing current [%]
0.0 - 99.0
0.0
C, T
-
DDS
Float
3
Defines motor magnetization current relative to P0305 (rated motor current).
Dependency:
Setting 0 causes calculation by P0340 = 1 (data entered from rating plate) or by P3900 = 1 - 3 (end of
quick commissioning). The calculated value is displayed in r0331.
r0330[0...2]
Rated motor slip [%]
- - - PERCEN
T
DDS Float 3
Displays nominal motor slip relative to P0310 (rated motor frequency) and P0311 (rated motor speed).
r0330[%] = ((P0310 - r0313 * (P0311/60))/P0310) * 100%
r0331[0...2]
Rated magnetization cur-
rent [A]
- - - - DDS Float 3
Displays calculated magnetizing current of motor.
