M68-2000 2-Axis Motion Controller

The M68-2000 is a dedicated 2‑axis motion controller designed for CNC and servo control applications. This compact controller provides coordinated motion for two axes with high‑speed interpolation, making it suitable for positioning tables, pick‑and‑place systems, and small CNC machinery. It operates with firmware version 2.40 and software version 3.1, offering a mature and stable control environment.

The controller features dedicated inputs for limit switches, home sensors, and emergency stop, as well as outputs for servo enable, direction, and pulse signals. It supports both step/direction and analog torque/speed interfaces, providing flexibility for various drive types. The M68‑2000 includes a user‑friendly interface for programming motion profiles, including linear and circular interpolation, with programmable acceleration and deceleration curves.

Typical Applications

• CNC milling and routing: Small table‑top machines with two linear axes.

• Pick‑and‑place systems: XY positioning for component placement.

• Laser engraving: Coordinated motion for beam positioning.

• Test and measurement: Automated probe positioning on semiconductor wafers.

Installation and Configuration

Mount the M68‑2000 on a DIN rail inside the control cabinet. Connect the 24 V DC power and the servo drives to the terminal blocks. Use shielded cables for pulse and analog signals. Configuration is performed via the software: set the resolution, acceleration, and speed parameters for each axis, and upload the motion program. The controller can be operated in standalone mode or as a slave to a PLC via the RS‑232 port. LED indicators show power, communication, and axis status.

Environmental and Compliance

The M68‑2000 complies with EN 61000‑6‑2 and EN 61000‑6‑4, carrying CE marking. It is RoHS compliant and designed for pollution degree 2 environments.

Conclusion

The M68‑2000 offers a cost‑effective, reliable solution for 2‑axis motion control in CNC and automation systems. Its versatile interfaces and mature firmware ensure precise, repeatable motion for a variety of industrial applications.
