Cable Resistance / R_Cable; Motor Series Inductance / Mot L_Series - Siemens SINAMICS G150 Manual

Dependency: Refer to: p0625, r1912
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note: The motor identification routine determines the stator resistance from the total stator resistance minus the cable
resistance (p0352).
p0352[0...n]

Cable resistance / R_cable

VECTOR_G Can be changed: C2(3), U, T
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: -
Min
0.00000 [ohm]
Description: Resistance of the power cable between the Motor Module and motor.
Dependency: Refer to: p7003
Caution: The cable resistance should be entered prior to motor data identification. If it is used subsequently, the difference by
which p0352 was changed must be subtracted from the stator resistance p0350 or motor data identification must be
repeated.
Notice: Parallel circuits with one winding system (p7003 = 0):
p0352 includes the feeder cable resistance of an individual Motor Module. The total feeder cable resistance is
obtained from p0352 divided by the number of activated Motor Modules (refer to r0395).
Parallel circuits with multi-winding system (p7003 = 1):
p0352 includes the complete feeder cable resistance and is directly added to the stator resistance (refer to r0395).
Note: The parameter influences the temperature adaptation of the stator resistance.
The motor identification sets the cable resistance to 20% of the measured total resistance if p0352 is zero at the time
that the measurement is made. If p0352 is not zero, then the value is subtracted from the measured total stator
resistance to calculate stator resistance p0350. In this case, p0350 is a minimum of 10% of the measured value.
Exception:
For parallel circuit configurations with one winding system (p07003 = 0), the cable resistance is directly measured. It
is important to note that only the component of an individual Motor Module is entered into p0352.
The cable resistance is reset when quick commissioning is exited with p3900 > 0.
p0353[0...n]

Motor series inductance / Mot L_series

VECTOR_G Can be changed: C2(3), U, T
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: -
Min
0.000 [mH]
Description: Sets the series inductance.
Note: For the automatic calculation with p0340 = 1, 3 or 4, the calculation of p1715 is influenced by p0353.
The series inductance is reset when quick commissioning is exited with p3900 > 0.
p0354[0...n] Motor rotor resistance cold / damping resistance d axis / Mot R_r cold/R_D d
VECTOR_G Can be changed: C2(3), U, T
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: PEM, REL
Min
0.00000 [ohm]
Description: Sets the rotor/secondary section resistance of the motor at the ambient temperature p0625.
For separately-excited synchronous motors: Sets the damping resistance in the rotor direction (d-axis).
This parameter value is automatically calculated using the motor model (p0340 = 1, 2) or using the motor data
identification routine (p1910) (not for separately-excited synchronous motors).
Dependency: Refer to: p0625
