Abstract
An auxiliary fast stop braking circuit is provided for an electronically controlled sewing machine having the capability to implement a single pattern of a repetitive stitch pattern by implementing needle bar release from its drive means and zero feed motion at the completion of the last stitch of the pattern. The auxiliary fast stop braking circuit is responsive to selection of a single pattern and to activation of the needle bar release solenoid to implement dynamic braking of the sewing machine motor.
