3.2 Processing Time of Communication Data
The following explains the processing time of the welding power source concerning the changeof I/O data in Fieldbus communication.
When an external device changes a single function by the I/O data, it takes approximately 20
ms until the change is reflected to the welding power source after the data reception is completed
in the welding power source. When changes are made to two or more functions, it takes
approximately 50 ms at maximum until all changes are reflected. (*1, *2）
When the welding power source sends I/O data, the status of the welding power source at thetime before [Communication cycle waiting time (*3)]+approx. 20 ms against the sending starttiming is reflected to the data. (*1)
*1
*2
*3

Delay may increase temporarily according to the CPU loaded conditions of the welding
power source.
When hardware operation is conducted by "Welding startup" and "Gas discharge", etc. ,additional delay will occur by the time the hardware starts working.
For instance, 0-10 ms communication cycle waiting time will occur when thecommunication interval of the I/O data is set to 10 ms.

Function

00

Welding start

Operates as welding starting being ON when 1. Does not work if
inching or retracting are operating ahead.

01Inching02Retract

Operates as inching or retracting being ON when 1. However,when both inching and retracting are 1, neither will be performed.
Inching and retracting do not work if welding starting is operating
ahead.

03

Gas purge

Operates as gas purge being ON when 1. Gas will be discharged
during welding startup regardless of whether gas discharge is
ON/OFF.

0

4

Welding detection

The welding detection function using auxiliary power becomes
ON when this value is set to 1. Does not work during welding
startup. Also, welding starting is given priority over welding
detection.
Normally, upon completion of welding, the stuck wire removal
function operates (refer to the Owner's Manual, 6.7.2.2 "F4:
Auto/Semi-auto mode", footnote 1), so this function is not used.

07

Watchdog

Used as the watchdog signal. This bit must alternate writing
between 0 and 1 every 0.5 seconds. When the watchdog signal is
not operating, data other than for stopping operation will not be
accepted.
If this bit does not change for more than 1 second, the welding
machine will have an error stop. However, if the watchdog signal
is not operating when the welding machine is started or recovers
from an error stop, the welding machine will output a warning,
and the error stop will not re-occur. The warning will be canceledwhen the watchdog signal begins operating.

7

Operation stop/
reset error

When 1, the welding power source stops operating, and theerror code is reset with E-000. When 1 is returned to 0, errors andwarnings are cleared, and the welding power source resumes
operation. However, as shown in appendix 1, welding powersource system errors and control power errors cannot be reset. In
such cases, the power to the welding power source must be shut off
and then restored.

2-

Welding condition
memory no.

Set when using the memory function of welding conditions(refer to the Owner's Manual, 6.5 "Memory Function of Welding
Conditions"). When this function will not be used, set the value to0.
Setting a welding condition memory number 1 through 100 will
set that number's corresponding saved welding condition to IN
data offset 4-29 (the saved welding condition can be checked, but
this operation by itself does not load the saved welding condition).
Setting the welding condition memory number to 0 will returnoffset 4-29 of the IN data to the currently enabled setting.

Welding condition
memory load

Setting the welding condition memory load to 1 will load thewelding condition of the number set to the welding condition
memory number.
However, note that if the setting change permission of offset
3/bit 7 is set to 1, immediately after the welding condition isloaded, the setting values for offset 4 and greater will be applied
as the currently enabled settings. When using to load welding
condition memory, normally set the setting change permission to0.
When both welding condition memory load and welding
condition memory write are set to 1, both operations are disabled.

6

Welding guidepermission

Use the welding guide function. (However, only welding
machines equipped with the welding guide function aresupported.)
When this bit is 1, the welding current is automatically set bysetting the "joint" and "thickness" in internal functions.
Specify and set the following internal function numbers.
"Joint": Function No.116"Plate thickness": Function No.117

7

Setting change
permission

When this bit is 1, the setting values of offset 4 and greater are
applied to the welding machine. When this bit is 0, the setting
values of offset 4 and greater are ignored by the welding machine.
However, function numbers of offsets 18, 21, 24, and 27 are notparameters that are changes for the welding machine, and so they
are always recognized. For example, when the setting change
permission is 0, and offset 18 (function (port 1) no.) is set, thevalues of offsets 19 and 20 (function (port 1) setting value) will not
be applied to the welding machine, but the function values alreadyset to the welding machine will be output to the IN data offsets 19
and 20.

Welding mode

Sets the welding mode (refer to the Owner's Manual, 6.6.1"Welding mode setting").
If a welding mode combination is set that does not exist, awarning is output, and the welding mode remains the same as it
was before the setting was made. However, when an automatic
machine is selected for an application even though a welding mode
without an automatic machine combination is selected, a warning
is not output and the application will be corrected to semi-auto.
Similarly, when penetration control is ON even though a welding
mode without penetration control combination is selected, awarning is not output and penetration control will be corrected to
be OFF.
The warning will be canceled when a correct combination for thewelding mode is set.

This setting for this bit is enabled only when the wire feed speed
setting of offset 8/bit 1 is 0 (welding current setting). When this bit
is 1, wire is fed at the wire feed speed setting of offset 11 and 12
only during inching and retracting. When this bit is 0, the wire
feed speed is set in reference to the welding current setting.
When the wire feed speed setting of offset 8/bit 1 is 1, (wire feed

4.7 Control Timing(1) Pre-flow/Post-flow
The timing for welding start and pre-flow/post-flow normally follows the timing described in"6.6.3.1 Crater OFF" in the Owner's Manual (read with "welding start" in place of "Torchswitch").
However, when gas purge is set to ON before welding startup, and then welding start is set to
ON while gas purge remains ON, the pre-flow period is eliminated and voltage output occurs
immediately. Conversely, regardless of whether gas purge is switched between ON/OFF after
welding is completed, there is a mandatory post-flow period in which gas purge cannot be
stopped.
The pre-flow and post-flow times can be set to 0.
(2) Sequence at welding startup and inching/retract/welding detection
The welding sequence determined by welding start ON/OFF operations is shown in the
diagram below.
Set welding conditions (welding mode, welding current, etc.) for starting welding to be at least
30 ms before welding start turns to ON. When the welding condition is changed simultaneouslywith welding start turns to ON, the welding condition changes of the moment of welding start
may not be applied correctly.
In the period from when welding start turns ON until the inverter (voltage output) turns OFF,inching, retract, and welding detection operations are not permitted. However, when inching or
retract are set to ON before welding start becomes ON, the welding start is not permitted. While
welding detection operation is occurring, in cases when welding start becomes ON, the welding
start is prioritized and the welding detection operation is stopped.
Set welding conditions for starting welding to be at least 30 ms before welding start turns to ON.
