Parameter Function
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%
r0331[0...2] Rated magnetization
current [A]
Displays calculated magnetizing current of motor.
r0332[0...2] Rated power factor
Displays power factor for motor.
Dependency: Value is calculated internally if P0308 (rated motor cosφ) set to 0; otherwise, value entered in P0308 is
displayed.
r0333[0...2] Rated motor torque [Nm] -
Displays rated motor torque.
Dependency: Value is calculated from P0307 (rated motor power) and P0311 (rated motor speed). r0333[Nm] =
(P0307[kW] * 1000) / ((P0311[1 / min] / 60) * 2 * Pi)
