Description: Displays the rated power factor for induction motors.
For IEC motors, the following applies (p0100 = 0):
For p0308 = 0, the internally calculated power factor is displayed.
For p0308 > 0, this value is displayed.
For NEMA motors, the following applies (p0100 = 1, 2):
For p0309 = 0, the internally calculated power factor is displayed.
For p0309 > 0, this value is converted into the power factor and displayed.
Dependency: If p0308 is not entered, the parameter is calculated from the rating plate parameters.
Note: The parameter is not used for synchronous motors (p0300 = 2xx).
Description: Displays the rated motor torque.
Dependency: IEC drives (p0100 = 0): unit Nm
NEMA drives (p0100 = 1): unit lbf ft
Note: For induction motors, r0333 is calculated from p0307 and p0311.
For synchronous motors, r0333 is calculated from p0305, p0316, p0327 and p0328.
Description: Sets the motor cooling system used.
Value: 0: Natural ventilation
1: Forced cooling
2: Liquid cooling
128: No fan
Dependency: For 1LA7 motors (p0300), the parameter is pre-set as a function of p0307 and p0311.
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note: The parameter influences the thermal 3-mass motor model.
1LA7 motors, frame size 56 are operated without fan.
Description: Displays the rated EMF of the motor.
Note: EMF: Electromotive force
