SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Description: Sets the motor pole pair number.
p0314 = 1: 2-pole motor
p0314 = 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.
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).
Description: Induction motors:
Sets the rated motor magnetizing current.
For p0320 = 0.000 the magnetizing current is internally calculated and displayed in r0331.
Synchronous motors:
Sets the rated motor short-circuit current.
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: The magnetizing current p0320 for induction motors is reset when quick commissioning is exited with p3900 > 0.
If, for induction motors, the magnetizing current p0320 is changed outside the commissioning phase (p0010 > 0),
then the magnetizing inductance p0360 is changed so that the EMF r0337 remains constant.
