INTRODUCTION

Clinton's Model 970 is an electronically controlled variable speed drive for industrial sewing machines.
The drive consists of a brushless DC Servo Mini-Taurus motor, controller with a microprocessor, speed
control and a programmable LCD display as an option. No clutches, brakes or synchronizer are used.
All components interact to give a fast accurate and reliable sewing machine drive. The components of
the system are shown in figure below.

The model 970 has outputs for a trimmer, footlift, wiper and needle cooler. It can be used to operate all
Clinton trimmers, as well as the Singer, Union Special, Pfaff, Juki and Brother undertrimmers and chain
stitch machines.

The programmable LCD display is used to select the trimmer type and other parameters.
See section III.
