Torque monitoring

In applications with fans, pumps or compressors with the flow characteristic, the torque
follows the speed according to a specific characteristic. An insufficient torque for fans
indicates that the power transmission from the motor to the load is interrupted. For pumps,
insufficient torque can indicate a leakage or dry-running.
The inverter monitors the torque based on the envelope curve depending on the speed
against a lower and upper torque.
If the torque lies in the impermissible range longer than time p2192, the inverter reacts as
specified in p2181.
The monitoring is not active below speed threshold 1 and above speed threshold 3.
