Power Limit Scaling / P_Max Scal; Moment Of Inertia Estimator Accelerating Torque Threshold Value; Moment Of Inertia Estimator Change Time Moment Of Inertia / J_Est T J; Moment Of Inertia Estimator Change Time Load / J_Est T Load - Siemens SINAMICS G150 Manual

2 Parameters
2.2 List of parameters
p1556[0...n]

Power limit scaling / P_max scal

VECTOR_G (n/M) Can be changed: T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
0.00
Description: Sets the scaling of the signal source for the motoring and negative regenerative power limit.
0 signifies no power limiting.
p1560[0...n] Moment of inertia estimator accelerating torque threshold value / J_est M thresh
VECTOR_G Can be changed: C2(3), U, T
(J_estimator)
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: -
Min
0.10 [%]
Description: Sets the threshold for the accelerating torque for the moment of inertia estimator.
The moment of inertia estimator is active above this threshold.
The value is referred to the rated torque (r0333).
Dependency: Refer to: p1400, p1561, p1562
Note: The moment of inertia estimation is inaccurate at very low accelerating torques/accelerating forces. As a
consequence, below this threshold, the estimator does not provide any new values.
p1561[0...n]

Moment of inertia estimator change time moment of inertia / J_est t J

VECTOR_G Can be changed: U, T
(J_estimator)
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: -
Min
10.00 [ms]
Description: Sets the change time for the moment of inertia for the moment of inertia estimator.
Lower values mean that faster changes are possible.
For a higher value, this estimated value is smoothed more significantly.
Dependency: Refer to: p1400, p1560, p1562
p1562[0...n]

Moment of inertia estimator change time load / J_est t load

VECTOR_G Can be changed: U, T
(J_estimator)
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: -
Min
5.00 [ms]
Description: Sets the change time for the load torque/load force for the moment of inertia estimator.
Lower values mean that faster changes are possible.
For a higher value, this estimated value is smoothed more significantly.
Dependency: Refer to: p1400, p1560, p1561
