User Manual EM303B General Purpose Inverter 101 No. Function Description Output Frequency Detection Range FDT1 (Disabled at JOG) When inverter is running (Except in JOG running mode), if the output frequency increases to the value of F9-12 (FDT1 Increasing Threshold), the output terminal is on. If the output frequency drops and is less than the value of F9-13 (FDT1 Decreasing Threshold), the output terminal is off. See 7.13.3 for details. 4 Output Frequency Detection Range FDT2 (Disabled at JOG) When inverter is running (Except in JOG mode), if the output frequency increases to the value of F9-14 (FDT2 Increasing Threshold), the output terminal is on.
If the output frequency drops and is less than the value of F9-15 (FDT2 Decreasing Threshold), the output terminal is off. See 7.13.3 for details. 5 Forward/Reverse (Enabled at Running) When inverter is running, if the motor reverses, the output terminal is on. If the motor forwards, the output terminal is off. 6 Frequency Input/Output Balance (Enabled at Running) When inverter is running, if output frequency= the setting frequency, the output terminal is on. 7 8 JOG When inverter is jogging, the output terminal is on. 9 Inverter Fault When inverter trips fault, the output terminal is on.
Upper Limit Frequency Reach(Enabled at Running) When the output frequency of inverter reaches the setting upper limit frequency of F0-17, the output terminal is on. 10 Lower Limit Frequency Reach(Enabled at Running) When the output frequency reached the lower limit frequency set by F0-18, the output terminal is on. (The output terminal will be off when accelerating to the lower limit frequency at the initial running.
When the output frequency exceeds the lower limit frequency at the first time, and then reaches lower limit frequency again, the output terminal is on.) 11 12 Not Used 13 Not Used Analog Variables Detection Range ADT1 If the input signal of analog input terminal> the value of ADT1 set by F7-05, the output terminal is on. See 7.9.2 for details. 14 Analog Variables Detection Range ADT2 If the input signal of analog input terminal> the value of ADT2 set by F7-07, the output terminal is on. See 7.9.2 for details. 15 Analog Variables Detection Range ADT3 If the input signal of analog input terminal> the value of ADT1 set by F7-09, the output terminal is on. See 7.9.2 for details.
16 Overload Alarming Output When the present current of inverter exceeds the overload detection scale and the remaining time exceeds the overload detection time. See 7.9.1 for details. 17
