7. Positioning of pulse motor for feeding - basic point
This adjustment should normally only be carried out if the step motor has been replaced.
Origin point positioning for feed is that the motor pinion with cam touches with the stopper pin and the
motor pinion turns from the position above at a designated angle in reverse direction, while feed regula-
tor gear turns for the feed regulator to stop at the the angle of feed ”0”. (This adjustment has been made
at the factory and is not needed for local maintenance/repair.)
Fine adjustment of feed amount: Adjustment is to be made by turning the screw on the motor bracket
support plate below the feed generating unit as shown on the next page.
It is recommended to adjust feed pitch with stretch stitch patterns such as pattern #17.
Note: Feed pitch for all stitch patterns can be adjusted with the screw A only.
It is desirable to adjust feed pitch with most needed stitch pattern.
