NOTE: If Slow Speed is set to a value higher that Fast Speed then Slow Speed is automatically
changed to equal the Fast Speed. Therefore, Slow Speed can never exceed Fast Speed.
Limits: Minimum - 0 Maximum - 10 Default - 5
Unit of Measure - RPM
Thread Break Enable Delay
When the machine is not running the Thread Break eyes are dark as in an actual Thread Break condition.
When the machine starts running, it takes a few seconds for the thread detection devices to report
properly. This setting delays when the Needle and Looper Thread Breaks become active.
Limits: Minimum - 0 Maximum - 5.0 Default - 1.0
Unit of Measure - Seconds
Thread Break Debounce
When the machine is not running the Thread Break eyes are dark as in an actual Thread Break condition.
Therefore, Needle and Looper Thread Breaks are not active until the machine has been running for the
time set by the Thread Break Enable Delay setting. During the process of sewing the needle and looper
thread may loosen or tighten causing the Thread Break Detect eyes to go dark. The Thread Break
Debounce gives the thread time to "settle down" in order to report an actual thread break. If this number
is set too low you may get false thread break errors. Conversely, if set to high, several stitches may pass
before the operator is alerted.
Limits: Minimum - 0 Maximum - 5.0 Default - 1.0
Unit of Measure - Seconds
Undertrimmer Delay
The Undertrimmer is the knife mechanism under the needle plate that trims the needle thread when
needed. The Undertrimmer activates during a jump move in a Sew and Jump pattern. During the jump
portion of a Sew and Jump pattern, the machine stops after it has moved the Needle Tail Length
distance. The machine then stops to allow for the Undertrimmer to activate. The Undertrimmer Delay is
the amount of time the jump move is delayed to allow the Undertrimmer to cut the needle thread. Once
undertrimming is complete the machine continues the jump move.
Limits: Minimum - 1.00 Maximum - 4.00 Default - 2.00
Unit of Measure - Seconds
