42 Chapter 5 Parameters
The signal is given 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 signal is given if the drive's output frequency is 0 and
the drive is in operating status.
10: Completion of simple PLC operation stages
The signal is given (pulse, 500ms) if the present stage of
PLC operation is finished.
11: PLC cycle completion indication
The signal (pulse, 500ms) is given if one cycle of PLC
operation is finished.
12: preset counting value arrival
13: reference length arrival
Refer to F7.33~F7.34.
14: preset length arrival
The signal is given if the setting of F9.15 (actual length) is
bigger than F9.14 (preset length) . The length counting
terminal is the one whose parameter (F7.03 or F7.04) is set
at 44.
15: drive ready (RDY)
The RDY signal is output when the drive has no fault, its DC
bus voltage is normal, the Start Prohibit function is disabled.
It is ready to start.
16:Drive fails
The signal is given 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 communication
protocol of EV1000.
18:Upper and lower limits of traverse frequency.
The signal will be given if the range of traverse frequency
calculated based on central frequency is higher than upper
limit of frequency (F0.12) or lower than the lower limit of
frequency (F0.13) , as shown in Figure5-45.

19: preset operating time out
The signal is given if the drive's total operating time (Fn.01)
reaches preset operating time (Fn.00) .
Note
When F7.04 is set at 44~46, the pulse output function of Y2 is
disabled automatically.

F7.13 Freq. arrival detection
range (FAR)
As shown in Figure 5-46, if the drive's output frequency is
within the detecting range of preset frequency, a pulse signal
will be output. It is complementary to No.1 function in Table
9-1.

F7.14~F7.15 is a complement to the No.2 function in Table
5-9. F7.16~F7.17 is a complement to the No.3 function in
Table 5-9. Their functions are same. Take F7.14~F7.15 for
example: when the drive's output frequency reaches FDT1
level, it outputs an indicating signal until its output frequency
drops below FDT1 level (FDT1 level-FDT1 lag) . As shown in
Figure 5-47.

AO1 and AO2 are analog output terminals.
Refer to section 3.3.2 for the output characteristics of AO1
and AO2, their analog output ranges are defined by F7.29.
Refer to Table 5-10 for the function of F7.26 and F7.27.
