Fig. 7-37 Schematic Diagram of ADT Detection
As shown in Fig. 7-37, a valid starting point has been set for the detection level. When
the percentage of analog input is above the detection level after offset processing, the ADT
function will be valid. The conditions for invalid ADT function are dependent on the
one-way downward hysteresis. When the conversion result of analog input decreases to less
than the result of “detection level - hysteresis”, the ADT function will be invalid.

Energy consumption braking is a braking method for quick deceleration by converting
the energy generated in deceleration into the thermal energy of the braking resistor. It is
suitable for braking under large-inertia loads or stop by rapid braking. In this case, it is
necessary to select the appropriate braking resistor and braking unit, as detailed in “0
Braking Resistor” and “0 Braking Unit”.
