Code 

Function 

Specifications 

OT0~OTF  General purpose output 0 ~ F  When IO0 is on, OT0 output at the same time (same from OT1 to OTF ) 
FN1~FNH  Function code output 1 ~ H 

When FUN1 code is read while sewing operation, FN1 output is reversed. 
(same from FN2 to FNH) 

OF1~OF8  Clamp output 1 ~ 8 

When IF1 is on, OF1 output is reversed (same OF2 to OF8 ) 

NO 

[NO]output 

Nothing is done 

T 

Trimmer output 

Trimming operation is done 

L 

Thread tension release output  Thread tension release operation is done 

W 

Wiper output 

Wiper operation is done 

PF 

Presser foot output 

Presser foot operation is done 

AFL 

Pneumatic two-step switch 
clamp low pressure output 

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. 

AFH 

Pneumatic two-step switch 
clamp high pressure output 

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. 

AFE 

Pneumatic two-step switch 
clamp excess pressure release 
output 

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. 

DHP 

Home position output 

When XY table is sopped on the home position, DHP output is turned on. 

D2H 

Second home position output 

When XY table is sopped on the second home position, DHP output is turned 
on. 

RED 

Preparation ready output 

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. 

DSW 

Sewing in progress output 

When the machine is sewing, DSW output is turned on. When machine is 
stopping on the home position, DSW output is turned off. 

SP 

Sewing machine rotation start 
output 

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. 

TSE 

Trimming start output 

When trimming sequence (down position) is started, TSE outpu 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. 

END 

Sewing completion output 

When a sewing pattern operation is finished, END output is turned on. 
When the next sewing is started, END output is turned off. 

DCS 

Halt code output 

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. 

DST 

Halt in progress output 

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. 

HPO 

Home returning in progress 
output 

While the operation of home returning by the home positioning key or HP 
signal, HPO outpu is turned on. 

ERR 

Error output 

When the error or message is displayed on the operation panel, ERR output 
is turned on. 

CUE 

Count up completion output 

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. 

CDE 

Countdown completion output  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. 

DTS 

Halt in progress output after 
upper thread sensor detection   

When the machine is on halt state with thread breakage, DTS output is 
turned on. When the machine restarts, DTS output is turned off.   

--1 

DO NOT USE 

DRT 

Sewing machine rotation in 
progress output 

While the machine is rotating, DRT output is turned on. 

(includes rotation in winding mode) 

DN 

Down position output 

When the needle is down position, DN output is turned on. 

CB 

Buzzer output 

While the buzzer in the operation panel is on, CB output is turned on. 
(including count up/countdown message display) 

UP 

Up position output 

When the needle is up position, UP output is turned on. 

PWR 

Power on output 

While power supply is on, PWR output signal is turned on. 

PUS 

Presser hoot home position 
output 

While presser foot is on the home position, PUS output is turned on. 

MSG 

Message display output 

When the message is displayed on the operation panel, ERR output is turned 
on.
