SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011
Description: Sets the stall current for synchronous motors (p0300 = 2xx).
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 parameter is used for the I2t monitoring of the motor (refer to p0611).
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.
Description: Sets the maximum motor speed.
Dependency: Refer to: p1082
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.
Notice: If p0322 is changed during quick commissioning (p0010 = 1), the maximum speed p1082, which is also associated
with quick commissioning, is pre-assigned accordingly.
