*Note: For pulse width recognition, a dedicated complex signal generator is required to generate signals with different pilot pulse widths to determine the motion direction, and the motion speed is adjusted according to the pulse frequency. For frequency recognition, the motion direction is determined solely by the frequency level, and the speed follows the user’s global speed setting (1–8x). Therefore, the requirements for user signals are simple, with only frequency modulation characteristics required.

Technical Notes

The stage is equipped with a high-performance two-phase stepper motor and achieves nanometer-level pulse resolution through advanced microstep subdivision technology. When used with the O’motion motion controller, it supports stepless speed regulation from 0.78 mm/s to 6.25 mm/s and features an adjustable jog function with a flexible setting range of 0.01–0.5 mm for jog distance. Users can realize precise forward and backward feeding motion through multiple control modes such as jog, creep and Hall stepless speed regulation.

In terms of system integration, the stage supports USB serial communication and adopts the standard ASCII O’motion instruction set, which is compatible with multiple operating systems including Windows, Linux, MacOS and Android, providing users with a convenient cross-platform development experience. Windows-version host computer control program samples and complete communication protocol documents are supplied with the product for easy secondary development and system integration by users.

The stage is equipped with threaded holes and locating dowel holes, providing ample flexibility for the installation of various tooling and fixtures. It adopts a USB serial communication interface, supports the ASCII O’motion communication protocol, and is fully compatible with multiple operating systems including Windows, Linux, MacOS and Android.

Adapter plates and right-angle brackets allow multiple stages to be configured into XY, XZ and XYZ multi-axis setups.
