Note
For a negative speed limit (r1087) the hysteresis is effective below the limit value and for a positive speed limit (r1084)
above the limit value.
If significant overshoot occurs in the maximum speed range (e.g. due to load shedding), you are advised to increase
the dynamic response of the speed controller (if possible). If this is insufficient, the hysteresis p2162 can only be
increased by more than 10% of the rated speed when the maximum speed (p0322) of the motor is sufficiently greater
than the speed limit p1082.

p2165[0...n] Load monitoring stall monitoring upper threshold / Stall_mon up thr
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: 3_1 Unit selection: p0505 Function diagram: 8013
Min:
0.00 [rpm] Max:
210000.00 [rpm] Factory setting:
0.00 [rpm]
Description: Sets the upper speed threshold of the stall monitoring of the pump or fan.
The lower limit is formed by the speed threshold 1 of the load monitoring (p2182).
The stall monitoring is active between p2182 and p2165.
Dependency: The following applies: p2182 < p2165
See also: p2181, p2182, p2193
See also: A07891, F07894, A07926
Note
For p2165 = 0 or p2165 < p2182, the following applies:
There is no special stall monitoring for the pump/fan, but only the remaining load monitoring functions (e.g. leakage
monitoring for a pump) for the pump or fan are active.
