AC Servo Drive for Packaging Machines
T3A / T3L Series servo drives are engineered for high-speed packaging systems such as VFFS, HFFS, flow wrapping, cartoning, and labeling machines. They solve real production issues such as unstable film feeding, inaccurate cutting length, inconsistent sealing timing, and servo synchronization errors.
Typical Problems in Packaging Machines
Inaccurate Film Feeding
Length deviation caused by poor servo tuning, unstable encoder feedback or incorrect acceleration curve.
Unstable Cutting Position
Servo synchronization delay leads to wrong sealing or cutting timing in high-speed operation.
Film Tension Fluctuation
Mechanical inertia mismatch between motor and load causes unstable tension control.
Servo Alarm / Overload
Incorrect parameter tuning or undersized drive leads to frequent fault trips.
What Our Engineers Ask Before Providing a Solution
✔ What type of packaging machine are you using (VFFS / HFFS / cartoning / labeling)?
✔ What is your required cycle speed (bags per minute or cycles per minute)?
✔ What is the load inertia of your mechanical transmission system?
✔ Are you currently facing positioning error or tension instability?
✔ What controller and servo brand are you replacing or upgrading from?
✔ Do you need high-speed response or high-torque stability priority?
These questions determine whether the problem is: mechanical mismatch, servo tuning issue, or system-level control instability.

Our Servo Engineering Solution for Packaging Systems
In packaging machinery, servo performance depends on system-level engineering rather than a single drive. Our approach focuses on mechanical analysis, motion control optimization, and multi-axis synchronization to improve machine stability, precision, and throughput.
Dynamic Load Modeling & System Matching
We analyze roller inertia, belt transmission, sealing mechanism load, and film tension variation. This ensures correct torque matching and stable operation under high-speed packaging conditions.
Multi-Axis Synchronization Strategy
Electronic gearing and cam profiling are applied to ensure precise coordination between feeding, sealing, and cutting axes, eliminating phase deviation at high cycle speeds.
Servo Parameter Optimization
Gain tuning, acceleration curve shaping, and jerk control optimization are applied based on real packaging cycle behavior, improving motion smoothness and reducing mechanical shock.
Film Tension Control
Real-time torque compensation and adaptive speed regulation maintain constant film tension, preventing stretching, slipping, or cutting deviation in flexible packaging systems.
High-Speed Stability & EMC Control
EMC filtering and disturbance suppression algorithms ensure stable operation in electrically noisy environments caused by heaters, motors, and sealing systems.
Machine-Level Performance Optimization
We evaluate system performance from throughput, reject rate, and mechanical wear perspective, improving long-term production efficiency and machine reliability.
