Pulse width setting range: 0.1 to 500ms, by 0.1ms
The output frequency when ON-state pulse width or OFF-
state pulse width is xed is as follows. The frequency over the
following frequency is limited.
1
Pulse width set value(ms) x 2
x 1000[Hz]
5.1.9 Output Low Cut Point
Set [D44: LOW CUT] to the low cut point.
Setting range: 0.0001Hz to 100% output frequency
If the output is less than or equal to the low cut point, the
output is 0Hz.
5.2 Settings Related to Communication
Function
Set the following parameters when output-2 is specied
for communication function. For more information on the
communication function, see the Instruction Manual for VJ Series
Communication Function (IM 77J1J11-01E).Parameters are
indicated inside the [ ].
5.2.1 Communication Protocol

LINK, PC-LINK WITH SUM, MODBUS ASCII, MODBUS RTU,
and LADDER in [F01: PROTOCOL].
5.2.2 Communication Address
Set the address number of the converter numerically in a
range of 1 to 99 in [F02: ADDRESS].
5.2.3 Baud Rate
Set the baud rate by selecting from among 1200, 2400, 4800,
9600, 19200, and 38400 bps in [F03: BAUD RATE].

Number of digits of decimal places (setting of D register
[D0003]) can be set.
Select and set among 0 to 5 digits in [F07: INPUT DEC PT].
5.3 Settings Related to Alarm Output
Set the following parameters when output-2 is specied for alarm
output.
5.3.1 Alarm Setpoints
Set the alarm setpoints of alarm-1 and alarm-2 in [E03: SET
POINT1] and [E04: SET POINT2] numerically.
• Setting range: A range of 0 to 100% of input range
• Setting resolution: 0.1%
5.3.2 Direction of Alarm Action
Select the direction of alarm-1 action and that of alarm-2
action from among HIGH ALM (high-limit alarm) and LOW
ALM (low-limit alarm) and set each in [E05: ALM1 ACTION]
(direction of alarm-1 action) or [E06: ALM2 ACTION]
(direction of alarm-2 action).
• To activate alarm status when input signal ≥ alarm setpoint,
select HIGH ALM.
• To activate alarm status when input signal ≤ alarm setpoint,
select LOW ALM.
5.3.3 Hysteresis
Set alarm-1 and alarm-2 hysteresis, in [E09: HYSTERESIS1]
and [E10: HYSTERESIS]. Hysteresis is a value added to the
alarm setpoint in order for an alarm status to be released (to
normal) after the alarm status has been activated. The alarm
status will be released in the following conditions, depending
on the direction of alarm action.
* When HIGH ALM (high-limit alarm) is set: Alarm is released
when input signal < (alarm setpoint - hysteresis).
* When LOW ALM (low-limit alarm) is set: Alarm is released
when input signal > (alarm setpoint + hysteresis).
• Setting range: A range of 0 to 100% of input range
• Setting resolution: 0.1%
5.3.4 Alarm ON Delay and Alarm OFF Delay
Set alarm-1 and alarm-2 ON delays in [E11: ON DELAY1] and
[E12: ON DELAY2] and then alarm-1 and alarm-2 OFF delays
in [E13: OFF DELAY1] and [E14: OFF DELAY2].
An alarm ON delay is a delay time from the establishment of
alarm condition to alarm output; an alarm OFF delay is a delay
time from the establishment of return-to-normal condition to
output.
• Setting range: 0 to 999 seconds
• Setting resolution: 1 second (Note that about 0.2 second
will be added to set time to prevent erroneous operation.)
For example, when an alarm ON delay is set to 1 second,
alarm output is generated if alarm status continues for
more than 1 second after the input value exceeds the
alarm setpoint. Further, when an alarm OFF delay is set
to 2 seconds, alarm output is released if normal condition
continues for more than 2 seconds after the input value has
returned to normal from the alarm status.
5.3.5 Direction of Relay Action
Set the direction of relay energizing in alarm-1 normal
condition and alarm-2 normal condition by selecting from
among NRM DE-ENERGIZED (de-energized under normal
condition) and NRM ENERGIZED (energized under normal
condition) in [E15: RL1 ACTION] and [E16: RL2 ACTION]
and set them.

Description of
alarm actions
The alarm is output if the
condition where the input value
is 80% or more of high-limit
alarm continues for 1 second
or more.
After the alarm is output, when
the condition where the input
value is less than 70% of
high-limit alarm continues for
2 seconds or more, the status
returns to normal.
The alarm is output if the
condition where the input value
is 15% or less of low-limit
alarm continues for 3 seconds
or more.
After the alarm is output, when
the condition where the input
value is more than 20% of
low-limit alarm continues for
4 seconds or more, the status
returns to normal.

on; however, it needs 10 to 15 minutes of warm-up before it
meets the specied performance.
For cleaning the instrument, use a soft and dry cloth.
8.1 Calibration Apparatus
• A calibrator (YOKOGAWA CA500 or equivalent)
• Setting tool for adjustment (Refer to "4.2 Connector for
Communication" in this manual.)
8.2 Calibration Procedure
1. Connect the instruments as shown in gure below. First adjust
the output-1 signal and then the output-2 signal.

2. Use the calibrator and apply input signals equivalent to 0, 25,
50, 75, and 100% of the input span to the product.
3. Then, check that the converter’s output signal shows a
frequency corresponding to 0, 25, 50, 75, and 100% of the
input span within the rated accuracy range.
Take the same calibration procedure for the output-2, and
conrm that the frequency of the output 2 is the same as that
of the output 1.
For alarm output, check the relay action by the alarm indicator
lamp or resistance of output terminals.
• When adjusting the input signal, use the VJ77 parameter
setting tool.
For adjustment using a setting tool, refer to the User’s Manual for
setting tool and “8. LIST OF PARAMETERS” in this manual.

comply EMC standards.
Note: When option code /C0 or /FB is specied, the
conformity to the safety and EMC standards is
excluded.
Note: When contactless AC switch is specied for the
output-1 signal code or output-2 signal code, it will not
comply with safety and EMC standards.
10. ENVIRONMENT STANDARD
EU RoHS directive: EN IEC 63000
(However, when contactless AC switch is specied for the
output signal, and su󰀩x code /C0 or /FB is specied, CE
marking is not applicable because the product does not
conform to safety and EMC standards.)
11. TRANSPORT AND STORAGE CONDITIONS
