This may be the case for rotating measurements (see p1960).
The torque limit p1520 can be re-calculated using p0340 = 1, 3 or 5.
Description: Displays the torque limit to limit the speed controller output.
Index: [0] = Upper limit
[1] = Lower limit
Description: Sets the signal source for the scaling of the upper torque limiting to limit the speed controller output without taking
into account the current and power limits.
Description: Sets the scaling of the stall limit for the start of field weakening.
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.
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: 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.
