Function
A torque band is monitored. This enables underload and overload conditions to be
recognized (e.g. ventilator not running correctly)
Comparison between current speed / torque curve with programmed envelope
curve. The upper and lower frequency curve can be specified via three supporting
points each. In addition a dead time until the function is triggered can be defined.
This avoids accidental triggering due to transient events.
For additional settings please refer to parameter list P2181 and following.
