（3） Core functional characteristics

1. Control mode and accuracy

Support dual mode operation of open-loop and closed-loop: closed-loop mode requires external sensors (encoders) to achieve position feedback, while open-loop mode is suitable for basic positioning scenarios;

Ultra high micro step resolution (1/2048 full step): significantly improves positioning accuracy and meets precision motion control requirements;

Trapezoidal speed curve: optimizes acceleration and deceleration during motion, reduces impact, and ensures smooth operation.

2. Feedback and Security Protection

Encoder input support: compatible with A/B orthogonal signals (TTL/RS-422 standard), with a sampling frequency of up to 60MHz, providing high-precision position feedback for closed-loop control;

Multiple switch protection: equipped with 2 limit switches (to prevent overtravel), 1 reference point switch (positioning calibration), and 1 index switch (precise triggering), all of which support programmable configuration;

Stall detection function: When the position error exceeds the programmable threshold (with the cooperation of sensors), the motor will automatically stop running to avoid equipment damage.

3. Communication and expansion capabilities

Communication interface: USB and RS-232 interfaces are standard to meet the command and control requirements of the computer;

Networking Expansion: Supports daisy chain network, with a maximum of 16 devices (USB interface) and 6 devices (RS-232 interface) connected to a single interface, suitable for multi axis collaborative control scenarios;

Manual control: Supports external analog joystick (Y cable can achieve 2D motion) and button box, making it convenient for on-site debugging and operation.

4. Software and programming support

Control software: Comes with PIMikroMove (graphical operation software) and PITerminal (command-line operation tool);

Programming support: Provides LabVIEW driver, Windows/Linux dynamic library, MATLAB library, compatible with mainstream programming environments;

Featured features: Support for launching macros (non-volatile storage, enabling independent operation), data logger (recording operational data such as speed/position/position error), watchdog timer (ensuring system stability).
