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.
p2166[0...n] Off delay n_act = n_set / t_del_off n_i=n_so
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 8011
Min:
0.0 [ms] Max:
10000.0 [ms] Factory setting:
200.0 [ms]
Description: Sets the switch-off delay time for the "speed setpoint - actual value deviation in tolerance t_off" signal/message (BO:
r2197.7).
Dependency: See also: p2163, p2164, r2197
p2167[0...n] Switch-on delay n_act = n_set / t_on n_act=n_set
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 8011
Min:
0.0 [ms] Max:
10000.0 [ms] Factory setting:
200.0 [ms]
Description: Sets the switch-on delay for the "speed setpoint - actual value deviation in tolerance t_on" signal/message (BO:
r2199.4).
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.
