SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011

Description: Displays the number of motor pole pairs. The value is used for internal calculations.

r0313 = 1: 2-pole motor

r0313 = 2: 4-pole motor, etc.

Dependency: For p0314 > 0, the entered value is displayed in r0313.

For p0314 = 0, the pole pair number (r0313) is automatically calculated from the rated power (p0307), rated fre-

quency (p0310) and rated speed (p0311).

Refer to: p0307, p0310, p0311, p0314

Note: For the automatic calculation, the pole pair number is set to the value of 2 if the rated speed or the rated frequency

is zero.

Description: Sets the motor pole pair number.

p0314 = 1: 2-pole motor

r0314 = 2: 4-pole motor, etc.

Dependency: For p0314 = 0, the pole pair number is automatically calculated from the rated frequency (p0310) and the rated

speed (p0311) and displayed in r0313.

Notice: If p0314 is changed during quick commissioning (p0010 = 1), the maximum speed p1082, which is also associated

with quick commissioning, is pre-assigned accordingly.

For induction motors, the value need only be input if the rated data of a generator is entered therefore resulting in a

negative rated slip. In this case, the number of pole pairs in r0313 is too low by 1 and must be manually corrected.

Description: Sets the torque constant of the synchronous motor.

p0316 = 0: The torque constant is calculated from the motor data.

p0316 > 0: The selected value is used as torque constant.

Dependency: Refer to: r0334

Caution: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-

mation in p0300 should be carefully observed when removing write protection.

Note: This parameter is not used for induction motors (p0300 = 1xx).
