Hysteresis value. For Underspeed operation, the Relay Release point is set to the Relay Trip point
plus the Hysteresis value. The hysteresis value is calculated by multiplying the hysteresis
percentage by the current trip frequency. If No Hysteresis (setting = 0) is selected, the Relay Trip
and Release points are identical, which can lead to chattering or cycling of the relay at input
frequencies hovering around the Relay Trip point.
Example: Using the Trip Frequency and Offset value as shown in the example above, the

Offset value. For Underspeed operation, the Relay Trip point is internally set to the Trip Frequency
minus the Offset value. The Offset value is equal to the Trip Frequency multiplied by the selected
Offset percentage.
Example: The Offset value is calculated as shown below.
