SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
Description: Sets the motor moment of inertia (without load).
Dependency: IEC drives (p0100 = 0): unit kg m^2
NEMA drives (p0100 = 1): unit lb ft^2
The parameter value is included, together with p0342, in the rated starting time of the motor.
Refer to: p0342, r0345
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 product of p0341 * p0342 is used when the speed controller (p0340 = 4) is calculated automatically.
Description: Sets the ratio between the total moment of inertia/mass (load + motor) and the intrinsic motor moment of iner-
tia/mass (no load).
Dependency: This means that together with p0341, the rated starting (accelerating time) of the motor is calculated for a vector
drive.
Refer to: p0341, r0345
Note: The product of p0341 * p0342 is used when the speed controller (p0340 = 4) is calculated automatically.
Description: Identified motor rated current
Description: Sets the motor weight.
Dependency: IEC drives (p0100 = 0): unit kg
NEMA drives (p0100 = 1): unit lb
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 model of the induction motor.
The parameter is not used for synchronous motors (p0300 = 2xx).
