Mitsubishi Electric MELSEC iQ-R Motion CPUs and MELSEC iQ-F Simple Motion modules are mid-to-premium tier Japanese-OEM multi-axis motor position controllers stocked by Flextech Industrial Supplies for Malaysian machine builders, system integrators, and automation engineers requiring closed-loop synchronised servo axis control from 2 axes to 64 axes on SSCNET III/H fibre optic or CC-Link IE TSN Ethernet motion networks.
Mitsubishi MELSEC motion control hardware represents one of the most established motion controller platforms in the Malaysian industrial automation market – the iQ-R and iQ-F platforms are deeply integrated with Mitsubishi MR-J4 and MR-J5 servo drives via SSCNET III/H, covering the full range of Malaysian machine builder positioning requirements from simple 2-axis X/Y positioners (iQ-F Simple Motion) through 32-axis coordinated robot and gantry systems (iQ-R Motion CPU). Flextech provides iQ-R and iQ-F motion system quotations within 24-48 hours from Puchong, Selangor.

About Mitsubishi MELSEC Motion: Two-Platform Architecture
Mitsubishi Electric's MELSEC motion control product line covers two distinct platforms - MELSEC iQ-R (high-end dedicated motion CPU, up to 64 real axes) and MELSEC iQ-F (compact PLC with Simple Motion positioning module, up to 16 axes) - unified by SSCNET III/H communication to Mitsubishi MR-J4/MR-J5 servo drives and MELSOFT GX Works3 + MT Works2 engineering software.
The two-platform architecture serves different Malaysian machine builder scale requirements: iQ-F Simple Motion for the majority of Malaysian multi-axis machine builds (2-16 servo axes at competitive system cost), and iQ-R Motion CPU for complex high-axis-count coordinated motion systems in automotive, semiconductor, and CNC applications requiring advanced cam profile, electronic gearing, and synchronous control functions.
Mitsubishi Motion Control Product Lines
| Platform | Module | Max Real Axes | Communication | Application |
| iQ-F PLC | LD77MS4 / LD77MS16 | 4 / 16 axes | SSCNET III/H | Compact multi-axis, 2-16 axes |
| iQ-F PLC | RD77MS4 / RD77MS16 | 4 / 16 axes | CC-Link IE TSN | Compact, MR-J5 compatible |
| iQ-R PLC | R16MTCPU | 16 real axes | SSCNET III/H | High-end motion, cam, sync |
| iQ-R PLC | R32MTCPU | 32 real axes | SSCNET III/H | Large multi-axis systems |
| iQ-R PLC | R64MTCPU | 64 real axes | SSCNET III/H | Maximum axis automotive/CNC |
Mitsubishi iQ-F Simple Motion modules (LD77MS and RD77MS series) are positioning modules within the MELSEC iQ-F compact PLC platform - the correct specification for the majority of Malaysian machine builder multi-axis positioning requirements. LD77MS4 controls 4 servo axes via SSCNET III/H connected to MR-J4 drives; LD77MS16 controls 16 axes. Motion functions include: point-to-point positioning, linear interpolation (2-axis), circular interpolation, JOG, home return, speed-position switching, and cam profile output for electronic cam applications.
The iQ-F Simple Motion approach - positioning module within a standard PLC, not a separate motion controller - reduces system hardware count and engineering tool count for Malaysian machine builders: iQ-F CPU + LD77MS module uses a single GX Works3 engineering environment for PLC logic + motion program, without requiring the separate MT Works2 motion programming tool needed for iQ-R Motion CPU.
Mitsubishi iQ-R Motion CPU (R16MTCPU, R32MTCPU, R64MTCPU) is the dedicated motion controller module within the MELSEC iQ-R high-end PLC platform - for complex multi-axis Malaysian machine applications exceeding the capability of Simple Motion modules. iQ-R Motion CPU capabilities include: up to 64 real servo axes per Motion CPU, advanced cam profile (user-defined cam data with up to 65,536 points), synchronous control with electronic gearing and electronic cam, high-speed positioning at 0.44 ms servo update cycle on SSCNET III/H, and multi-axis interpolation with simultaneous path control across all real axes.
Technical Specifications: SSCNET III/H Motion Network
SSCNET III/H (Servo System Controller NETwork III/H) is Mitsubishi Electric's dedicated fibre optic motion bus - the communication backbone between MELSEC Motion CPUs/Simple Motion modules and MR-J4/MR-J5 servo drives in Malaysian machine builds.
Transmission medium: Optical fibre cable - immune to electromagnetic interference from inverters, high-frequency drives, and welding equipment common in Malaysian automotive and metalworking plants. This EMI immunity is a material advantage over Ethernet-based motion networks in high-interference Malaysian factory environments.
Cycle time: 0.44 ms servo update interval on SSCNET III/H - deterministic, jitter-free position command update to all connected MR-J4 servo drives simultaneously. Deterministic timing enables synchronised multi-axis interpolation without inter-axis timing variation.
Axis connection: Daisy-chain topology - up to 96 MR-J4 servo drives per SSCNET III/H bus on a single R64MTCPU. Each drive connects to the next with a single fibre cable, eliminating network switches and simplifying panel wiring versus Ethernet-based servo networks.
Compatibility: SSCNET III/H is Mitsubishi-proprietary - MR-J4 and MR-J5 servo drives only. Non-Mitsubishi servo drives (Panasonic MINAS A6, Yaskawa Sigma, Siemens SINAMICS S) are not SSCNET III/H compatible. Malaysian machine builders standardising on MELSEC motion control commit to Mitsubishi MR-J4/MR-J5 servo drive ecosystem.
iQ-F Simple Motion vs iQ-R Motion CPU: Selection Guide
Specify iQ-F Simple Motion (LD77MS/RD77MS) when: (1) Axis count is 16 or fewer. (2) Single GX Works3 tool for both PLC logic and motion program is preferred. (3) Point-to-point and linear interpolation positioning covers the application - no advanced cam profile or 64-axis synchronous control required. (4) System cost optimisation is a priority - Simple Motion module cost is significantly below iQ-R Motion CPU at equivalent basic positioning capability.
Specify iQ-R Motion CPU (R16MTCPU/R32MTCPU/R64MTCPU) when: (1) Axis count exceeds 16, or application requires up to 64 real axes. (2) Advanced cam profile (electronic cam), electronic gearing, or synchronous multi-axis control is required. (3) Dedicated motion CPU isolation from PLC logic CPU provides real-time performance separation. (4) Malaysian automotive assembly, semiconductor handler, or CNC gantry applications requiring complex coordinated path control.
Applications in Malaysian Manufacturing
Automotive assembly (Shah Alam, Rawang, Johor) - R32MTCPU or R64MTCPU on 12-32 axis robotic welding positioner, transfer press feeder, and body assembly jig systems in Malaysian Tier 1 automotive plants. SSCNET III/H fibre optic eliminates EMI interference from welding current on Ethernet cables in these high-interference environments.
CNC machining - Mitsubishi CNC platforms (M800S, M80V) with integrated iQ-R motion on X/Y/Z and rotary axes in Malaysian component machining job shops. MR-J4 or MR-J5 servo drives connect directly via SSCNET III/H to Mitsubishi CNC controllers.
Semiconductor and electronics (Penang, Kulim) - iQ-F Simple Motion with LD77MS16 on 8-12 axis pick-and-place delta robot systems, die bonding stage control, and tape-and-reel machine index drives where 16-axis Simple Motion module covers the positioning requirement at below-iQ-R-Motion-CPU system cost.
Packaging machinery - LD77MS4 (4-axis Simple Motion) on flying shear registration drive, form-fill-seal film feed servo, and cartoning index table control in Malaysian OEM packaging machine builders where 2-4 synchronised servo axes with iQ-F PLC logic integration is the standard system architecture.
NIMP 2030 (National Industrial Master Plan 2030) Industry 4.0 manufacturing digitisation initiatives drive Malaysian adoption of networked servo motion systems - MELSEC iQ-R and iQ-F motion data (position, speed, following error, current) is accessible via CC-Link IE Field to Mitsubishi SCADA and MES integration, supporting the production data connectivity NIMP 2030 mandates.
