Parameter Function
P0309[0...2] Rated motor efficiency
[%]
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]
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]
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 inverter type and its rating data.
r0313[0...2] Motor pole pairs
Displays number of motor pole pairs that the inverter 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
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 cur-
rent [%]
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 [%]
Displays nominal motor slip relative to P0310 (rated motor frequency) and P0311 (rated motor speed).
r0330[%] = ((P0310 - r0313 * (P0311 / 60)) / P0310) * 100%
