The YSC-8361 AC Servo System is a controller designed for industrial sewing machines, emphasizing safe and correct operation. Users are advised to read the manual thoroughly before use and keep it for future reference.
Function Description
The YSC-8361 controller manages various sewing machine operations, including different tacking modes, constant-stitch sewing, bar-tacking, and lower thread counting. It integrates a user-friendly interface with a keypad and a seven-segment display for settings and feedback.
Tacking Modes:
- Single Start Tacking: Allows setting forward (A) and backward (B) stitches, both in a range of 1-15. The sewing process involves A stitches forward, then B stitches backward, followed by normal sewing. If A stitches are set to 0, the process starts with B stitches backward, then normal sewing.
- Double Start Tacking: Similar to single start tacking but with a double sequence of forward (A) and backward (B) stitches, both in a range of 1-15. The sewing process is A stitches forward, B stitches backward, A stitches forward, B stitches backward, then normal sewing. If A stitches are 0, it performs B stitches backward, B stitches forward, B stitches backward, then normal sewing.
- Single End Tacking: Sets backward (C) and forward (D) stitches, both in a range of 1-15. The sewing process involves C stitches backward, then D stitches forward, concluding the sewing. If A stitches are 0, it performs C stitches backward, then ends.
- Double End Tacking: Similar to single end tacking but with a double sequence of backward (C) and forward (D) stitches, both in a range of 1-15. The sewing process is C stitches backward, D stitches forward, C stitches backward, D stitches forward, then ends. If A stitches are 0, it performs C stitches backward, C stitches forward, C stitches backward, then ends.
- Free Sewing: When the pedal is stepped forward, selected start tacking is done automatically, followed by normal sewing. The machine stops when the pedal returns to balance. Stepping the pedal backward automatically performs end tacking, trimming, and wiping (if selected).
Specialized Sewing Modes:
- Constant-Stitch Sewing: Completes F and G stitches E times when the pedal is stepped forward. The system performs the set number of segments and times; if stitches are zero, the machine stops immediately.
- Bar-Tacking Sewing: Completes all seams of bar tacking (A, B, C, D sections) E times, with automatic trimming, when the pedal is stepped forward. The pedal must return to balance for the next sewing cycle.
Counters:
- Lower Thread Counter: Activated by setting A11 to "1". Users can enter the interface to view and adjust the initial value. The counter decreases by 1 for every 10 stitches. If the count falls below 1, a warning sounds, and the display blinks. Sewing can resume after pressing 'S', and the counter continues. Pressing 'S' again returns the display to the initial value.
- Production Counter: Activated by setting A11 to "1". Accessible via SN F2 in the special function interface. It displays the number of stitches and trims for the current process. Pressing 'S' saves the data. The counter warns if the number of stitches collected exceeds 90% or if the number of trimming times exceeds the collected amount by 1. The counter can be cleared by pressing 'S' in the clear counter interface.
