2.2 List of parameters
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).
Refer to: p2165, p2181, p2191, p2193
Refer to: A07891, F07894, A07926
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.
Description: Display and connector output of the smoothed speed actual value for messages.
Dependency: Refer to: p2153
Description: Sets the absolute current threshold for the messages.
"I_act >= I_threshold p2170" (BO: r2197.8)
"I_act < I_threshold p2170" (BO: r2198.8)
Dependency: Refer to: p2171
Description: Sets the delay time for the comparison of the current actual value (r0068) with the current threshold value (p2170).
Dependency: Refer to: p2170
