3) How to check each test program No.
① CP-1 (Input signal check)
State of input of switches and sensors is indicated on the 8 LEDs.
The table below is the list of LED indication, and you can understand to which LED each switch or each
sensor is assigned.
Letters in the table of LED indication
• EMS ........Temporary stop switch
• PDET ........Feed reference signal The signal occurs one time during one rotation of the sewing machine
when the needle bar angle is between 125˚ and 155˚.
• TG ........TG signal The signal occurs 45 times (an interval of 8˚) during one rotation of the sewing
machine.
• UDET ........Sewing machine up-position signal The signal occurs one time during one rotation of the
sewing machine when the needle bar angle is between 34˚ and 48˚.
• DDET ........Sewing machine down-position signal The signal occurs one time during rotation of the
sewing machine when the needle bar angle is between 80˚ and 123˚.
• AUDET........Sewing machine upper dead point position signal The signal occurs one time during one
rotation of the sewing machine when the needle bar angle is between 5˚ and 30˚.
＊ The aforementioned needle bar angles are those detected from the encoder of the main motor.
＊ Input line Nos, 7 and 8 correspond to the key switch of the operation box provided with AW-2D and
PGM -7.
