2 Parameters
2.2 List of parameters
Description: Displays the torque constant of the synchronous motor used.
Dependency: IEC drives (p0100 = 0): unit Nm / A
NEMA drives (p0100 = 1): unit lbf ft / A
Note: This parameter is not used for induction motors (p0300 = 1xx).
For synchronous motors, parameter r0334 is calculated from p0305, p0307 and p0311.
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
Description: Setting to automatically calculate motor parameters and U/f open-loop and closed-loop control parameters from the
rating plate data.
Value: 0: No calculation
1: Complete calculation
2: Calculation of equivalent circuit diagram parameters
3: Calculation of closed-loop control parameters
4: Calculation of controller parameters
5: Calculation of technological limits and threshold values
