Which servo-system parameters matter most when sourcing a packaging machine?
• Positioning accuracy within ±0.1mm, repeatability ±0.05mm, governs film cut registration.
• Rated/peak torque must cover film-tension peaks; keep ≥1.5x load margin.
• Servo bandwidth ≥1kHz with PLC scan ≤2ms for high-speed cycle synchronization.
• Encoder ≥17bit, support EtherCAT/PROFINET for multi-axis synchronization.
• Verify brand (Yaskawa/Panasonic/Inovance), spare-part lead time, and FAT acceptance.
