MELSEC iQ-F Series


Synchronous/Cam Controls Contribute to Higher Performance of Small-sized Equipment

The Simple Motion module is provided with synchronous and cam controls required for food processing machines and packaging machines. Combined with the Mitsubishi Electric's high-performance servo amplifier, the Simple Motion module enables downsizing of machinery while achieving outstanding performance. In addition, our extensive engineering environment allows you to create desired systems with ease.

Central Control via SSCNETIII/H Boosts Efficiency in Startup

The Simple Motion module can consolidate multiple servo amplifier parameters, shortening the startup time further. Also, operation information, such as power consumption and total power consumption of the servo amplifiers, can be monitored in real time, which enables further reduction in maintenance time.

Connection with various drive products Upgraded

Not only rotary servo motors but also linear servo motors, direct drive motors, FR-A800 series inverters, and products of Mitsubishi Electric servo system partners are connectable.

(Note-1): When using a partner product or the inverter FR-A800, use one whose version supports the Simple Motion module.

The Simple Motion Module Opens up Many Possibilities for Higher Performance

High-speed Synchronous Network SSCNETIII/H


  • Communications speed is increased to 150 Mbps full duplex (equivalent to 300 Mbps half duplex), three times faster than the conventional speed.
    System response is dramatically improved.
  • Smooth control of a machine is possible using high-speed serial communications with a cycle time of 0.222 ms.
  • Synchronous communications are achieved with SSCNETIII/H, offering technical advantages for machines that require deterministic control.
  • Long distance wiring is possible up to 3200 m (10498.69 ft.) per system (maximum of 100 m (328.08 ft.) between stations x control axes up to 32 axes), suitable for large-scale systems.
  • SSCNETIII/H compatible and SSCNETIII compatible servo amplifiers can be used together.
    (The communications speed when SSCNETIII compatible products are used together in the same system: 150 Mbps full duplex)
  • (Note): SSCNET (Servo System Controller Network)

Positioning Control

Positioning control is easily performed with a sequence program starting positioning data of a point table. To respond to extensive applications, various positioning controls are available: Linear interpolation, 2-axis circular interpolation, fixed-pitch feed, and continuous trajectory controls, etc.

Synchronous/Cam controls

Advanced synchronous control

The advanced synchronous control is the software-based control that can be used as an alternative to mechanical control such as gear, shaft, clutch, speed change gear, and cam.
The settings are easily made with parameters on MELSOFT GX Works3. In addition, the output axes for the synchronous control are operated with a cam.

  [Command generation axis]
Command generation axis is the axis that performs only the command generation.
It is controlled independently of other axes connected to servo amplifiers. (not counted as a control axis)

Cam auto-generation

Cams for rotary knife can be generated automatically.
An ideal cam data can be created just by registering sheet length, synchronous width, and cam resolution to the specified device memory on GOT screen.

Mark Detection Function

The actual position of the servo motor can be obtained based on the inputs from the sensor that detects the registration marks printed on the highspeed moving film. By compensating the cutter axis position errors based on those inputs from the sensor, the film can be cut at the set position.

Engineering Environment

Easy point-and-click programming architecture MELSOFT GX Works3

This software supports the whole product development cycle - creation, startup, debugging and maintenance of sequence programs, parameters, positioning/cam data.
