Description:
Sets the scaling of the stall limit for the start of field weakening.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Danger:
If the stall current limit is increased, then the q current setpoint can exceed the stall limit; as a consequence, a
hysteresis effect can occur when loading and unloading.
Description:
Sets the signal source for the scaling of the lower torque limiting to limit the speed controller output without taking into
account the current and power limits.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
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:
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
