Settings for NAVI Mode

4-1. NAVI Mode Functions and Settings

4

In [NAVI mode], frequently changed settings can be easily configured.
Settings for four functions can be configured.

RUN :

Normal Sensing Operation

TEACH : Teaching Mode

This indicates normal sensing operation. Incident light intensity is displayed in real
time. The factory setting is that the ‘threshold value’ cannot be changed directly.
When the ‘Adjust Lock Function’ in ‘PRO5 Mode’ is disabled, manual fine adjustment
of the ‘threshold value’ can be performed during normal sensing operation.
The threshold value can be confirmed by turning the jog switch (Refer to p.59). In
addition, key lock function can also be set (Refer to p.59).

This mode sets the ‘threshold value’ by utilizing teaching.

When using FX-301(P)(-HS) or FX-305(P) normal mode

The ‘threshold value’ can be set with any of the 3 teaching methods, ‘2-level
teaching’, ‘limit teaching’ and ‘full-auto teaching’.

2-level teaching is a method of setting the threshold value by teaching the
amplifier unit two different status conditions - sensing object present and sensing
object absent.
The ‘threshold value’ is usually set using this method.

Sensing operation * Sensing operation when ‘threshold value’

can be fine adjusted

Teaches only the status condition in which no sensing object is within sensing
range (status in which incident light intensity is stable). This method is used to set
a ‘threshold value’ for conducting sensing in the presence of a background, or
when extremely small objects are to be detected.

1-level Teaching

When using FX-305(P) window comparator mode
The ‘threshold value’ can be set with any of the 3 teaching methods, ‘1-level
teaching’, ‘2-level teaching’ and ‘3-level teaching’. By setting two ‘threshold
values’, both ON and OFF can occur between the two threshold value levels.

This sets the shift value to any desired value, and sets the threshold values (1_SL,
2_SL) by means of 1-level teaching.

3-level Teaching

This carries out 3-level teaching (P-1, P-2, P-3) and sets the threshold value
(1_SL) between A and B and the threshold value (2_SL) between B and C as
shown in the diagram below.
After teaching, P-1, P-2 and P-3 are automatically assigned in ascending order to
‘A’, ‘B’, and ‘C’.

ADJ : Threshold Value Fine Adjustment Mode

This mode allows fine adjustment of the ‘threshold value’ setting.
When the incident light intensity display has been selected, the threshold value
can be adjusted in increments as low as a one digit.
When the percentage display has been selected, the threshold value can be
adjusted in increments of one digit (varies depending on the ‘threshold value’).
However, when FX-305(P) is in window comparator mode, the percentage display
function cannot be utilized.

PRO1 mode is used mainly for configuring the details of basic settings.

: Response Time Change Function

The response times for the FX-301(P)(-HS) can be switched among five levels:
H-SP (ultra high-speed), FAST (high-speed), S-D (reduced intensity), STD (standard)
and LONG (long-range). The FX-305(P) can be switched among six levels: the same
as above without the S-D (reduced intensity) level but with STDF (standard 2) and
U-LG (ultra long-range) levels. (The switching of response times among these levels
will cause corresponding changes to the sensing range.)
* FX-301(P)(-HS):The factory setting is ‘STD (standard)’.

FX-305(P): The factory setting is ‘STDF (standard 2)’.

Note: If the interference prevention function is set to , the response time will become doubled.

Refer to p.27 for setting procedure

Timer Setting Function

Four different timer operations can be selected; Without timer / OFF-delay / ON­delay / ONE SHOT. The available timer periods are 0.5 ms and 1 to 9,999 ms.
* The settings allow timer operation to be switched among Without timer / OFF-

delay / ON-delay / ONE SHOT timer when in ‘NAVI mode’.

For output 1, six different timer operations can be selected: Without timer / OFF­delay / ON-delay / ONE SHOT / ON-delay • OFF-delay / ON-delay • ONE SHOT.
For output 2, four different timer operations can be selected: Without timer / OFF­delay / ON-delay / ONE SHOT.
The range of available timer periods is;
Output 1: 0.5 ms, 1 to 9,999 ms
Output 2: 0.5 ms, 1 to 500 ms

* OFF-delay : Extends the output signal for a fixed period of time.

This function is useful if the output signal is so short that the connected device
cannot respond.

ON-delay : Neglects short output signals. As only long signals are extracted, this function

is useful for detecting if a line is clogged, or for sensing only objects taking a
long time to travel.

ONE SHOT: Outputs a fixed width signal upon sensing.

This function is useful when the input specifications of the connected device
require a signal of fixed width.

ON-delay • OFF-delay : The ON-delay and the OFF-delay timer functions can operate

simultaneously.

ON-delay • ONE SHOT: The ON-delay and the ONE SHOT timer functions can operate

PRO4 mode is used mainly for configuring the communications with sub units.
* FX-301(P)-HS is not equipped with an optical communication function, so the PRO4 mode cannot be set.

:

Setting Condition Copy Function

By utilizing the optical communications function, the settings information from the
operating amplifier can be copied to other connected units. (Except for data bank
contents) In addition, copying will not be carried out for FX-301(P) and FX-305(P)
units in which the optical communication function has been locked.
Note) It is not possible to communicate setting information between FX-301(P), FX-301B/G/H(P) and

FX-305(P) units when using the setting condition copy function. Therefore, if units of different models
need to be connected together, then units of the same model should be connected side-by-side.

Refer to p.64 for setting procedure

:

Remote Data Bank Load Setting Function

By utilizing optical communication, settings within the data banks of each connected
amplifier can be loaded all at once. However, channel data will not be loaded for
FX-301(P) and FX-305(P) units in which the optical communication setting function
has been locked. Setting information can be quickly changed during reconfiguration.

Refer to p.45 for setting procedure

:

Remote Data Bank Save Setting Function

This function allows the current configuration setting information for all connected
amplifiers to be saved into the respective data banks.
Saves on the labor required to store individual settings, one-by-one, for each amplifier. Up to 3 sets of
configuration settings information can be saved for each amplifier. However, in FX-301(P) or FX-305(P) units
in which the optical communications settings change function has been locked, information will not be saved.

Refer to p.46 for setting procedure

The optical communications function

When copying settings information from the CH4 unit to other
higher connected units: Use the copy function at the CH4 unit.

When copying settings information from the CH1 unit to other higher connected units:
Use the copy function at the CH1 unit.

Example: when 16 units are connected in the side-by-side configuration.

Direction of communication

The FX-301(P) and FX-305(P) incorporate an optical communication function. By utilizing optical communications, interference can
be prevented and configuration settings information can be copied among connected amplifiers. Optical communications can occur
only in the direction shown in the diagram below. The maximum number of communicating units is 16, including the main unit.
Also, note that optical communication cannot be used when the line settings are being changed (when indicators are blinking) and
when PRO mode is set. Be aware that sensing operations will not be possible when the optical communication feature is in use.
If using optical communication with the FX-301(P)(previous version unit) or FX-301B/G/H(P)(blue / green / infrared LED)
together with the FX-301(P)(updated version unit) or FX-305(P), optical communication may not work properly
depending on the order of connection. Refer to ‘Points to note when combining sensor types’ (P.5) for further details.

If the optical communication setting change function has been locked when attempting to carry out copy / load
/ save operations on all amplifiers at once using the setting condition copy function, remote data bank setting
function or remote data bank save setting function while in PRO mode, only the amplifier being configured will
be locked. As a result, copy / load / save operations can be carried out on except the locked units.
* The factory setting is ‘Lock OFF’.

10-1. PRO6 Mode Functions and Settings

PRO6 mode is exclusive to the FX-305(P).
This mode allows both the sensing mode (Output 1: normal / window comparator / rising differential / trailing differential,
Output 2: normal / alarm output / error output) and the hysteresis for window comparator mode to be configured.

: Normal Mode

:

Window Comparator Mode

:

Rising differential /
Trailing differential Mode

This is a sensing mode for setting a single ‘threshold value’ and turning output ON
or OFF.
* The factory setting is ‘normal mode’.

Drops in light amounts due to problems such as broken fibers or dirty tips are
detected and output. If output 1 threshold value teaching is carried out, output 2 is
set to the value of output 1 shifted by the set margin amount. This allows drops in
margin light amounts due to dust or other particles to be detected and output.

This is a sensing mode for setting two threshold values and tuning output ON or
OFF within the set range.
The teaching method can be selected from 1-level teaching, 2-level teaching or
3-level teaching.

This is a mode for canceling out gradual changes in light amount, so that only
sudden changes are sensed when the incident light amount increases or
decreases.
