Description: Sets the scaling of the signal source for the motoring and negative regenerative power limit.
0 signifies no power limiting.
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.
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
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
