User Manual of A90 Series Inverter AI% Detection Analog level Hysteresis 0 Output terminal Time (s) 0 Invalid Invalid Valid Time (s) As shown in Fig. 7-37, a valid starting point has been set for the detection level. When Fig. 7-37 Schematic Diagram of ADT Detection 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”. 238 Function Function code Parameter description Unit Default setting Attribute code name F15.30 Options of energy consumption braking function 0: Invalid 1:
