MELSEC-Q Series

CC-Link IE Field

CC-Link IE Field Network

  • The new industrial Ethernet field network with high flexibility enables intelligent manufacturing systems to perform high speed I/O control and Motion control simultaneously.
  • The network wiring layout is highly flexible to best fit the needs of the application. Choose from line, star, or mixed line and star topology.
  • QD77GF can be used as the master station of CC-Link IE Field Network, and connected to a wide variety of devices, such as I/O devices.
  • Shorten tact time by using the 1Gbps CC-Link IE Field Network.
  • Based on Ethernet standards, cables and connectors are widely available around the world.

Deterministic and synchronized communication

Synchronous control and interpolation functions are achieved with the synchronized communication of CC-Link IE Field Network, being applied to machines which need synchronous control such as food machineries and processing machines.

Flexible Network Topology

Line, star, and line/star mixed topologies are available for the CC-Link IE Field Network wiring layout.

Line/star mixed topology

Star topology is available using an industrial switching HUB.
HUB applied: DT135TX (manufactured by Mitsubishi Electric System & Service Co., Ltd.)

Line topology

The Simple Motion modules (Master station) can be connected to slave devices without using a HUB, which reduces cost.

CC-Link IE Field Network Servo Amplifier MR-J4-GF

  • Having a superior control function of MR-J4 series, MR-J4-GF supports CC-Link IE Field network.
  • Together with the Simple Motion module, advanced synchronous control and interpolation control are enabled.

Positioning Control

  • To respond to various applications, a machine can be controlled by various control methods such as linear interpolation control, 2-axis circular interpolation control, fixed-pitch feed control, and continuous trajectory control.
  • Automatic operation can be executed by setting the positioning addresses and speeds, etc., to a sequence program.
  • Powerful sub-functions are available such as M codes, skip function, speed change function, and target position change function.

Synchronous Control/Cam Control

  • Achieve synchronous control and cam control by using input pulses from a synchronous encoder or virtual servo amplifier.
  • Use an incremental synchronous encoder with the directly built-in interface of QD77GF.
  • Further improve the synchronization accuracy with the phase compensation function, designed to compensate for synchronous encoder delays.

Control Flow

The start of positioning operation by the Simple Motion module is programmed in PLC CPU.
The Simple Motion module starts operation from the designated positioning data No. and continues operation until the operation pattern ends.
