  • Features
  • Spec・Dimensions
  • System Configuration

Safety Motion function can be added to the RC8A.

This function achieves harmonious coexistence of humans with robots while ensuring safety and high productivity.
Using this function, robots can be operated at a safe speed and stopped by monitoring the status of robots and humans.

Technical Feature

  • Compact design

    World's smallest* high-performance 8-axis controller
    This small and lightweight product has a high degree of design flexibility and is space-saving.
    ※As of December 2016, according to Denso Wave, in the case of robot controllers for 6-axis robots (3 kw class)

  • Excellent ease of operation

    More user-friendly menu structure and enhanced
    usability are achieved.
    Improved GUI and functions shorten time needed
    for robot introduction.

  • Meets global standards and has
    capability to adapt to standards

    ● Support for open networks [ORiN]
    ● Many certifications obtained
     ・ ISO 10218-1:2011/CE (standard, UL)
     ・ UL (UL)
     ・ PLe /SIL3 (standard, UL)
     ・ PLd/SIL2 (safety motion)
     ・ KCs (standard, safety motion)
    ● Support for global network standards
     ・ CC-Link
     ・ DeviceNet
     ・ Ethernet/IP
     ・ EtherCAT

  • Great potential for expansion

    This product enables robots to connect with and control
    various devices, meeting diversified needs by
    ● Since control programs can be written by accessing
    the provider from PacScript, robots can be controlled
    from the RC8 with a provider that is compatible with
    external devices.
    ● By developing a provider, connecting with and
    controlling various products are possible.
    * For details, including how to develop it, contact our
    sales representative.
    The control panel of the multi-functional teaching
    pendant can be customized easily from WINCAPS®III.
