Turn ON the upper DIP SW No. 2 located on the right side of the operation box panel, and pressing the stan-

dard screen key

, press ten key "1" to enter the adjustment screen.

Starting angle of the 1st hook thread trimming cylinder drive can be set.

The angle at which the rod of thread trimming lever enters the cam is specified.

Ending angle of the 1st hook thread trimming cylinder drive can be set.

Angle at which thread is actually trimmed is specified.

Starting angle of the 2nd hook thread trimming solenoid drive can be set.

The angle at which the rod of thread trimming lever enters the cam is specified.

Maximum speed of the longitudinal movement of the loop clamp feed unit can be

set.

Standard setting : 2,000 Unit : PPS

Standard speed of the loop clamp feed unit is determined at the necessary speed

for actually performing sewing work.

If the speed is set at more than 2,000, the speed of the loop clamp feed unit is in-

creased and the cycle time of the machine is increased. However, it is necessary to

actually limit the handling time within 0.5s and not substantial to increase the speed

more than 2,000.

Further, speed is inverse proportion to driving torque. If the speed is increased, the

torque is decreased, and drawing force of belt loop is decreased.
