Function

Single-axis motion control

The 1771-HS1 is specifically designed for single-axis servo control and supports high-precision motion control tasks such as position control, speed control, and acceleration management.

It works in conjunction with feedback devices such as encoders and resolvers to provide precise closed-loop control.

Data processing and program storage

The MML program and motion parameters are stored through a 32 KB memory card, supporting complex motion trajectories and control logic.

The RS-232 port supports program upload/download, debugging and parameter adjustment, facilitating system development and maintenance.

Feedback and Signal Processing

Support encoder feedback (10V DC isolated output, 250 kHz/20 kHz differential or single-ended input) and resolver feedback (excitation of the resolver stator through sine/cosine signals).

The AUX FDBK port provides auxiliary encoder power supply and feedback signal processing.

Emergency stop and rapid I/O

The Axis E-Stop I/O port supports emergency stop signals and rapid I/O responses to ensure system security and real-time control.

It can be connected to the handheld programming terminal (1771-HD) to modify system variables and parameters through the Offline Development System (ODS).

Diagnosis and Monitoring

It is equipped with 4 LED indicator lights for real-time monitoring of the module status (power supply, operation, errors, etc.).

Support diagnostic testing and troubleshoot through switches and buttons.

Flexible system integration

Seamlessly integrated with the 1771 I/O rack and PLC-5 controller, it supports a variety of external devices (such as solenoid valves, indicators, AC motor starters).

The portable programming terminal (1771-HD) provides a convenient operation interface and displays 4 lines of x 16 character error messages or menus.

Application scenarios

Industrial Automation and Motion Control

It is suitable for scenarios that require single-axis precise motion control, such as CNC machine tools, robot arms, conveyor belt positioning and packaging equipment.

The control of complex motion trajectories is achieved through high-precision feedback (encoders or resolvers).

Manufacturing and Assembly Line

It is used for single-axis servo drive control in automated production lines, such as part positioning, cutting or assembly tasks.

Its rapid I/O and emergency stop functions ensure the efficiency and safety of the production line.

Process control

It is used in industrial processes that require precise control of a single motion axis, such as pumping stations, valve control or the movement of mechanical arms.

It is applicable to the chemical, pharmaceutical or food processing industries to monitor and adjust the operating status of equipment.

Maintenance and upgrade of old systems: Applicable to traditional automation systems based on PLC-5, especially when factories need to continue using existing equipment.

It can be used as a transitional module to support migration to modern ControlLogix systems.

Testing and Debugging: The RS-232 port and the handheld programming terminal (1771-HD) facilitate on-site debugging and program modification, and are suitable for motion control systems in the development and testing stages.
