*1
When a smaller value is set, the feed timing is advanced.
Setting can be carried out in units of 2°.
Normal
The proportional feed time for each stitch is reduced from normal in order to prevent
needle deflection.
* This may be limited by the sewing speed.
When a smaller value is set, the test feeding speed in the Y axis direction becomes
slower.
Setting can be carried out in units of 100 Hz.
When a smaller value is set, the test feeding speed in the X axis direction becomes
slower.
Setting can be carried out in units of 50 Hz.
When a smaller value is set, the test feeding speed in the Y axis direction becomes
slower.
Setting can be carried out in units of 50 Hz.
When a smaller value is set, the test feeding speed in the θ axis direction becomes
slower.
Setting can be carried out in units of 50 Hz.
After sewing is finished, home position detection is not carried out.
Home position detection is carried out for the number of sewing cycles set.
When a larger value is set, the home position detection speed in the X axis direction
becomes slower.
Setting can be carried out in units of 0.1 ms.
When a larger value is set, the home position detection speed in the Y axis direction
becomes slower.
Setting can be carried out in units of 0.1 ms.
When a larger value is set, the home position detection speed in the θ axis direction
becomes slower.
Setting can be carried out in units of 0.1 ms.
