2.2 List of parameters
Description: Sets the current limit for output load identification.
A missing output load is displayed using the "Output load not available" message (r2197.11 = 1).
This message is output with a delay time (p2180).
Dependency: Refer to: p2180
Notice: For synchronous motors the output current can be almost zero under no load conditions.
Note: Missing output load is signaled in the following cases:
- the motor is not connected.
- a phase failure has occurred.
Description: Sets the delay time for the message "output load not available" (r2197.11 = 1).
Dependency: Refer to: p2179
Description: Sets the response when evaluating the load monitoring.
Value: 0: Load monitoring disabled
1: A07920 for torque/speed too low
2: A07921 for torque/speed too high
3: A07922 for torque/speed out of tolerance
4: F07923 for torque/speed too low
5: F07924 for torque/speed too high
6: F07925 for torque/speed out of tolerance
Dependency: Refer to: p2182, p2183, p2184, p2185, p2186, p2187, p2188, p2189, p2190, p2192, p2193, r2198, p3230, p3231
Note: The response to the faults F07923 ... F07925 can be set.
This parameter setting has no effect on the production of fault F07936.
Description: Sets the speed/torque envelope curve for load monitoring.
The envelope curve (upper and lower envelope curve) is defined as follows based on 3 speed thresholds:
p2182 (n_threshold 1) --> p2185 (M_threshold 1, upper), p2186 (M_threshold 1, lower)
p2183 (n_threshold 2) --> p2187 (M_threshold 2, upper), p2188 (M_threshold 2, lower)
p2184 (n_threshold 3) --> p2189 (M_threshold 3, upper), p2190 (M_threshold 3, lower)
