FL.06. This function is usually used in overload pre-alarm. See Fig. 5-74. 5: Low voltage lock-up signal (LU) The terminal outputs the indicating signal if the DC bus voltage is lower than the low voltage limit, and the LED displays “P.oFF”. 6: External stopping command (EXT) The terminal outputs the indicating signal if the drive outputs tripping signal caused by external fault (E015). 7: High limit of frequency (FHL) The terminal outputs the indicating signal if the preset frequency is higher than upper limit of frequency and the operating frequency reaches the upper limit of frequency. 8: Lower limit of frequency (FLL) The terminal outputs the indicating signal if the preset frequency is higher than lower limit of frequency and the operating frequency reaches the lower limit of frequency. 9: Zero-speed running The terminal outputs the indicating signal if the drive’s output frequency is 0 and the drive is in operating status. 10: Completion of simple PLC operation stages The terminal outputs the indicating signal (pulse signal, 500ms width) if the present stage of PLC operation is finished. 11: PLC cycle completion indication The terminal outputs the indicating signal (signal pulse, 500ms width) if one cycle of PLC operation is finished. 12: preset counting value arriving 13: reference length arriving indication Refer to F7.33~F7.34 for terminals 12 and 13. 14: preset length arrival indication The terminal outputs the indicating signal if the actual length defined by F9.15 is longer than the length defined by F9.14. Function of terminal X1~X8 should be set to No.44 function. 15: drive ready (RDY) If RDY signal is output, it means the drive has no fault, its DC bus voltage is normal and it can receive starting command. 16: Drive fails The terminal outputs the indicating signal if the drive has faults. 17: extended function 1 of host The output signal of terminal Y1, Y2 or TC is directly controlled by a serial port. Refer to the communicating protocol of EV2000. 18: Upper and lower limits of traverse operating frequency If traverse operating function is selected, an indicating signal will be output if the traverse operating frequency calculated by central frequency is higher than upper limit of frequency (F0.12) or lower than the lower limit of frequency (F0.13), as shown in Fig. 5-46. Before limiting amplitude Upper limit of freq Lower limit of freq. Traverse operation Y1: upper and lower limit of traverse operation After limiting amplitude Central freq. Fig. 5-46 Traverse operating amplitude control 19: preset operating time out The terminal outputs the indicating signal if the drive’s total operating time (Fn.01) reaches preset operating time (Fn.00). F7.13 Frequency arriving signal (FAR) Range:0.00~650.00Hz 【2.50Hz】 As shown in Fig. 5-47, if the drive’s output frequency is within the detecting range of preset frequency, a pulse signal will be output. 1/2 detecting range Time Time Y Preset freq. Output Fig. 5-47 Frequency arriving signal F7.14 FDT1 level Range: 0.00~650.00Hz【50.00Hz】 F7.15 FDT1 lag Range: 0.00~650.00Hz【1.00Hz】 F7.16 FDT2 level Range: 0.00~650.00Hz【25.00Hz】 F7.17 FDT2 lag Range: 0.00~650.00Hz【1.00Hz】 F7.14~F7.15 is a complement to the No.2 function in Table 5-11. F7.16~F7.17 is a complement to the No.3 function in Table 5-11. Their functions are the same. Take F7.14~F7.15 for example: when the drive’s output frequency reaches a certain preset frequency (FDT1 level), it outputs an indicating signal until its output frequency drops below a certain frequency of FDT1 level (FDT1 level-FDT1 lag), as shown in Fig. 5-48.
