2.2 List of parameters
The moment of inertia estimator is active above this threshold.
The value is referred to the rated torque (r0333).
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1400, p1561, p1562
Note: The moment of inertia estimation is inaccurate at very low accelerating torques. 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: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1400, p1560, p1562
Description: Sets the change time for the load torque 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: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1400, p1560, p1561
Description: Display and connector output for the monitored load torque in the positive direction of rotation.
The moment of inertia estimator estimates the load torque drawn while the speed is constant.
Dependency: Refer to: p1400, p1560, p1561
Description: Display and connector output for the monitored load torque in the negative direction of rotation.
The moment of inertia estimator estimates the load torque drawn while the speed is constant.
Dependency: Refer to: p1400, p1560, p1561
