2) CP-2 (XY motor / origin sensor check)
Inching operation of the X/Y motor, operation of origin retrieval, and the status of X/Y origin sensors are dis-
played.
1. Preparation
At first, press the key to start origin retrieval for needle thread clamp and work clamp foot/thread trimmer
motors. The presser foot assumes the lowering condition. After the completion of preparation, the sewing
LED is turn on.
2. Operation
3) CP-3 (Continuous operation)
After the setting of continuous operation, the condition moves to the continuous
operation mode.
Turn off the power supply to close the continuous operation mode.
1. Rest time setting
Press the and keys to set up the rest time.
Setting is possible within the range of 0 ~ 9900ms in the unit of 100ms. (Initial
value: 2000ms)
After the completion of setting, press the key.
2. Origin retrieval enable/disable setting at the end of sewing
Press the and keys to set up whether origin retrieval is enabled or
disabled at the end of sewing.
A0: Disable (Initial value)
A1: Every 100 sewing cycles
A2: Every sewing cycle
After the completion of setting, press the key to recover ordinary display.
3. Continuous operation
After the completion of setting, set up the pattern numbers, etc., in the same
manner as that for ordinary operation.
After the completion of sewing, origin retrieval of the X/Y/work clamp foot/thread
trimmer/needle thread clamp motors is conducted if “origin retrieval enabled”
has been set as per 2. above. In this case, automatic sewing operation is
restarted after the lapse of the rest time specified as per 1. above.
To stop continuous operation, press ON the Start SW during the rest time. [E
50] is displayed and operation is suspended.
According to the conditions of the selected X/Y origin sensors, “0” or
“1” is displayed. Changeover is possible by pressing the key.
Using the and keys, the selected X/Y motors are
driven in the directions of +/- in 0.1mm steps.
(Caution) Because of circular interpolation, even the mo-
tors not selected are also driven.
Used to change over the selective condition of the X motor
(X origin sensor) or the Y motor (Y origin sensor) with the
key.
Using the Start SW, origin retrieval of X/Y motors is effected for both shafts.
Used to display whether the X motor (X origin sensor) or
the Y motor (Y origin sensor) is selected. Changeover is
possible by pressing the key.
X enlargement / reduction scale rate LED lit: X motor (X
origin sensor)
Y enlargement / reduction scale rate LED lit: Y motor (Y
origin sensor)
