Monitoring for torque deviation
Based on the envelope curve shown below and dependent on the speed, the torque is
monitored against a lower and upper torque. The inverter linearly interpolates the
intermediate values.
Principle of operation
The inverter monitors the motor torque for speeds between threshold value 1 and threshold
value 3.
If the torque lies outside the envelope curve for longer than the time set in p2192, then the
response defined in p2181 is initiated.
The torque is not monitored for speeds between 0 and speed threshold 1 (p2182) - as well
as between speed threshold 3 (p2184 and the maximum speed (p1082).

Description
Load monitoring delay time (factory setting 10 s)
After the motor is switched on, if the "LOW" signal is present at the associated
digital input for longer than this time, the inverter signals a load failure (F07936).
