User Manual of EM760 High-Performance Inverter As shown in the figure above, 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. Function number of ADT1 output terminal: 21. Function number of ADT2 output terminal: 22. 6.6.7 Current reach detection Current reached:
In running status, and when the output current is greater than the current reach detection value (F15.44), the current output is valid. In non-running status, or when the output current is less than or equal to the current reach detection value (F15.44) - CDT hysteresis (F15.45), the current output is invalid. In other cases, current output status remains unchanged. Between current reach detection value (F15.44) - CDT hysteresis (F15.45) and current reach detection value (F15.44), the terminal remains in the previous status. Function number of current reach output terminal: 40. 6.6.8 Torque reach detection Torque reach:
In running status, and when |output torque| is greater than |torque reach detection value (F15.46)|, the current output is valid. In non-running status, or when |output torque| is less than or equal to |torque reach detection value (F15.46)| - TDT hysteresis (F15.47), the current output is invalid. In other cases, current output status remains unchanged. Between torque reach detection value (F15.46) - TDT hysteresis (F15.47) and torque reach detection value (F15.46), the terminal remains in the previous status. Function number of torque reach output terminal: 41.
