SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009

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: 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: Non-ventilated

1: Forced cooling

2: Liquid cooling

128: No fan

Dependency: For 1LA7 motors (refer to p0300), the parameter is preset as a function of p0307 and p0311.

Caution: This parameter is automatically preset for motors from the motor list (p0301). When selecting a catalog motor, this

parameter cannot be changed (write protection). 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: Electromagnetic force
