  • Integrating a Two-Axis SERVOPACK and Controller saves 34 mm in width.
  • The I/O required for equipment control and an Ethernet port are provided as standard features to allow you to build a small-scale equipment system based around just this one unit (no PLC required).
  • Up to six axes can be configured (two internal axes plus four external axes connected via MECHATROLINK-Ⅲ).
  • You can use Σ-7C SERVOPACKs for equipment modularization or for distributed control systems.
