Load monitoring

During load monitoring, the current speed/torque curve is compared with the set

speed/torque curve (p2182 to p2190). If the current value is outside the programmed

tolerance bandwidth, a fault or alarm is triggered depending on parameter p2181. The fault

or alarm message can be delayed by means of parameter p2192 to prevent false alarms

caused by brief transitional states.
