p2168[0...n] Load monitoring stall monitoring torque threshold / Stall_mon M_thresh
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: 7_1 Unit selection: p0505 Function diagram: 8013
Min:
0.00 [Nm]
Max:
20000000.00 [Nm]
Factory setting:
10000000.00 [Nm]
Description: Sets the torque threshold of the stall monitoring of the pump or fan.
If, in the monitored speed range from p2182 to p2165, the torque exceeds this threshold, then this is evaluated as
either the motor having stalled or heavy-duty starting.
Dependency: For pumps, the following applies (p2193 = 4):
- the leakage characteristic must lie below the torque threshold for the stall monitoring
- the torque threshold for dry running operation must lie below the torque threshold for stall monitoring
For fans, the following applies (p2193 = 5):
- the torque threshold for the stall monitoring must lie above the torque threshold to identify belt breakage (p2191).

Note
The following applies for p2168 = 0:
The special stall monitoring for pump/fan is deactivated.
Then, only the remaining load monitoring functions (e.g. the leakage monitoring for a pump) for pump or fan are
realized.
