19 Preset operating time out

In Table 5-11:

0: Drive running signal (RUN)

When the drive is in operating status, there will be

running indication signal output by this terminal.

1: Frequency arriving signal (FAR)

See F7.13.

2: Frequency detection threshold (FDT1)

See F7.14~F7.15.

3: Frequency detection threshold (FDT2)

See F7.16~F7.17.

4: Overload signal (OL)

The terminal outputs the indicating signal if the drive’s

output current is higher than the value defined by FL.05

and the overload time is longer than the time defined by 

66 Chapter 5 Parameter Introductions

EV2000 Series Universal Variable Speed Drive User Manual

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

Y1: upper and lower limit

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.

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
