Function
When IO0 is on, OT0 output at the same time (same from OT1 to OTF )
When FUN1 code is read while sewing operation, FN1 output is reversed.
(same from FN2 to FNH)
When IF1 is on, OF1 output is reversed (same OF2 to OF4 )
Nothing is done
Trimming operation is done
Wiper operation is done
Presser foot operation is done
When A2F input is on first time, AFL output is turned on.
Setting is effective when [Program mode > Clamp > Pneumatic two-step
switch clamp ON/OFF (AF2)] is on.
When A2F input is on second time, AFH output is turned on.
Setting is effective when [Program mode > Clamp > Pneumatic two-step
switch clamp ON/OFF (AF2)] is on.
When A2F input is on third time, AFE output is turned on.
Setting is effective when [Program mode > Clamp > Pneumatic two-step
switch clamp ON/OFF (AF2)] is on.
When XY table is stopped on the home position, DHP output is turned on.
When XY table is stopped on the second home position, D2H output is turned
on.
When the machine is ready state (when clamp output is on), RED output is
turned on. When machine is start sewing, RED is turned off.
When the machine is sewing, DSW output is turned on. When machine is
stopping on the home position, DSW output is turned off.
After non stitch feed, when the sewing machine start to rotate, SP output is
turned on. When home positioning is executed, SP output is turned off.
When trimming sequence (down position) is started, TSE output is turned on.
When trimming sequence is finished (when all the outputs of T, L and W are
turned off), TSE output is turned off.
When a sewing pattern operation is finished, END output is turned on.
When the next sewing is started, END output is turned off.
When the halt code data (USTP, DSTP) is read while sewing, DCS output is
turned on. When the machine restarts DCS output is turned off.
When the machine is on halt state, DST output is turned on. When the
machine restarts DST output is turned off. However, it is not output while
stopping by the USTP code or the DSTP code.
While the operation of home returning by the home positioning key or HP
signal, HPO output is turned on.
When the error or message is displayed on the operation panel, ERR output
is turned on.
When the current value of up counter is reached at counter set value, CUE
output signal is turned on. When the current value is cleared, CUE output is
turned off.
When the current value of down counter is reached at 0, CDE output signal is
turned on. When the current value is initialized, CDE output is turned off.
When the machine is on halt state with thread breakage, DTS output is
turned on. When the machine restarts, DTS output is turned off.
While the machine is rotating, DRT output is turned on.
(includes rotation in winding mode)
When the needle is down position, DN output is turned on.
While the buzzer in the operation panel is on, CB output is turned on.
(including count up/countdown message display)
When the needle is up position, UP output is turned on.
While power supply is on, PWR output signal is turned on.
While presser foot is on the home position, PUS output is turned on.
