Synchronization errors in multiple linear electric cylinders (i.e., position differences during movement) are mainly affected by the following three essential factors:

Mechanical Installation: The Physical Foundation of Synchronization Accuracy

The installation parallelism and base rigidity of each linear electric cylinder directly affect synchronization performance.

If the parallelism deviation during installation exceeds 0.05 mm, or the base is deformed, the motion resistance of each linear electric cylinder will become inconsistent. Even with synchronized commands, the actual movement of the cylinders will show deviations.

It is recommended to use a laser interferometer to calibrate parallelism during installation, and select a highly rigid mounting base to avoid synchronization offset caused by vibration or load fluctuation.

Servo System: The Power Core of Consistent Response

Performance matching between servo motors and drivers is critical.

Selecting servo products with fast response, small torque fluctuation and high consistency ensures that all linear electric cylinders are fully synchronized during startup, acceleration and deceleration after receiving commands, avoiding errors caused by motor response delay or performance differences. High-quality servo systems can control command response time at the millisecond level, providing power support for synchronization accuracy.

Control Program: The Intelligent Brain of High Precision Synchronization

As industry experience shows, the core of synchronizing multiple linear electric cylinders lies in program design.

Professional synchronization algorithms programmed via a host computer or motion controller enable precise simultaneous issuance of commands and real-time feedback correction for each linear electric cylinder. For example, the virtual master control mode allows all linear electric cylinders to move based on the same virtual axis, reducing synchronization errors by more than 50%.

The synchronization accuracy of multiple linear electric cylinders is not a fixed parameter, but a goal that can be continuously optimized through system design. Based on a single-cylinder accuracy of ±0.02 mm, standardized mechanical installation, matched high-quality servo systems and professional control programs can achieve different levels of synchronization accuracy ranging from ±0.05 mm to ±0.03 mm.
