Core strengths of this unit: Built-in Class A EMC filter + integrated braking chopper + high low-speed torque via open-loop vector control. It thoroughly resolves industry pain points including sensor interference, violent start-stop impact, film stretching and wrinkling in packaging & 印刷装置. The 5.5kW power rating matches main traction drives for medium-small standalone packaging machines.
場合 1: Fully Automatic High-Speed Plastic Bag Making Machine (Food/Clothing Bags)
- 機器構成
Main traction motor: 5.5kW 3-phase asynchronous motor driving integrated rollers for film feeding, longitudinal sealing, transverse sealing and winding
インバータ: 6SE6440-2AD25-5CA1 without BOP panel; speed regulated via PLC 0–10V analog signal
Matching components: Integrated braking chopper + compatible braking resistor 6SE6400-4BD21-2DA0; S7-200CN PLC for overall machine logic control
- Original On-Site Pain Points (Before Model Replacement)
- Old non-filter inverters caused frequent false triggering of color mark photoelectric sensors, resulting in ±3mm bag length deviation and high reject rates.
- DC bus overvoltage alarms occurred during high-speed emergency stops and speed reduction for roll change; poor stop buffering led to elongated films and misaligned seals.
- Insufficient starting torque at low speeds caused slipping of thin PE films and material stacking at machine startup.
- Retrofit Solutions with 6SE6440-2AD25-5CA1
- Class A EMC Filter Eliminates Interference: Built-in filter suppresses IGBT high-frequency harmonics, eliminating noise in color mark and edge correction analog signals; bag length error stabilized within ±0.5mm.
- Integrated Braking Chopper Enables Smooth Deceleration: Rapid dissipation of regenerative energy prevents film stretching during 120m/min emergency stops with precise longitudinal and transverse seal alignment.
- センサーレスベクトル制御: Full torque output at 0Hz eliminates thin film slipping during low-speed feeding; supports stepless speed regulation from 10–120m/min.
- Pre-set multi-speed parameters: One-key switching among standby low speed, production high speed and cleaning low speed.
- On-Site Operation Results
Single-shift reject rate reduced by 75%; no sensor false alarms during continuous operation. No extra input filter required, simplified cabinet wiring and 20% lower overall retrofit cost.
場合 2: モデル 1000 Paper/Film Slitter (Adhesive Labels, Kraft Paper, PET Film)
- Drive Station Matching
5.5kW motor drives main traction roller paired with 6SE6440-2AD25-5CA1; magnetic powder brake provides passive unwinding tension, while independent low-power MM440 units control rewinders.
- Core Process Requirements
Slitting demands constant linear speed and stable tension during acceleration/deceleration to avoid film/paper shifting, wrinkling and breakage. The machine is fitted with edge correction photoelectric sensors and tension analog acquisition modules highly sensitive to electromagnetic noise.
- Model Matching Advantages
- Class A filter isolates inverter noise to prevent drift of edge correction analog signals and web wandering during wide-width slitting.
- Fast dynamic response under vector mode delivers automatic torque compensation during acceleration/deceleration for constant-tension material transport.
- Built-in braking unit supports frequent start-stop roll changes, eliminating A0911 DC overvoltage faults; replaces external braking units to save cabinet space.
