Q04UDVCPU Mitsubishi Melsec-Q series CPU Module

Product parameters

CPU type: Q series general-purpose CPU, supporting integrated logic control and motion control.

Program capacity: 60k steps (standard), maximum expandable to 120k steps; The data storage is 32k words.

Processing speed: Basic instructions 0.034μs per step, application instructions starting from 0.1μs per step. The high-speed processing capability meets the requirements of complex logical operations.

Motion control capability: Supports up to 4-axis pulse output (differential drive), with a maximum pulse frequency of 200kHz, enabling positioning, speed control, and interpolation functions (linear/circular interpolation).

I/O expansion capability: Through Q series substrate expansion, it supports up to 4096 digital I/O points and 512 analog channels, and is compatible with various Q series I/O modules and special function modules (such as temperature control, high-speed counting modules).

Communication interface: Built-in 1 Ethernet port (supporting TCP/IP, MC protocol, CC-Link IE Field), 1 RS-232C port (for programming or connecting peripheral devices), and can expand fieldbus modules such as CC-Link and Profibus.

Power requirement: DC 5V (provided by Q series power module), power consumption approximately 12W.

Environmental adaptability: Operating temperature 0°C-55°C, storage temperature -20 °C-70°C, relative humidity 5%-95% (no condensation), protection grade IP20 (needs to be installed in a control cabinet).

Function

Integrated logic and motion control: 4-axis pulse control (such as servo motor positioning) can be achieved without additional motion control modules, and it supports interpolation function, making it suitable for small multi-axis equipment (such as dispensing machines, small CNC machine tools).

High-speed data processing: With a basic instruction speed as fast as 0.034μs, it can handle complex logic control, timer/counter interlocking, and multi-variable process regulation (such as PID control).

Rich communication and expansion: Connect HMI, SCADA system or MES via Ethernet, and support CC-Link IE Field industrial Ethernet protocol for distributed control; Expandable special modules such as analog quantity, temperature, and weighing can meet diverse signal acquisition and control requirements.

High reliability design: Equipped with self-diagnostic functions such as hardware watchdog, power monitoring, and program verification, it supports online modification of programs and hot plugging of modules (for some modules), reducing downtime for maintenance.

Programming convenience: With the GX Works3 programming software, it supports languages such as ladder diagram, SCL, and ST (Structured Text), and has a built-in dedicated instruction library for motion control, simplifying multi-axis linkage programming.

Application scenarios

Small multi-axis equipment: such as 4-axis dispensing machines, small assembly robots, and laser engraving machines, achieve high-precision positioning and trajectory control (linear/circular interpolation).

Medium-scale production lines: Control assembly lines with 10 to 20 workstations (such as electronic component assembly lines), taking into account both logical control (equipment interlocking, safety interlocking) and local motion control (such as positioning of handling manipulators).

Hybrid control scenarios: In food packaging machines and printing equipment, simultaneously handle sensor signal logic judgment, servo motor drive (feeding, cutting positioning), temperature/pressure and other process parameter adjustment.

Distributed control system: As a workshop-level control unit, it connects to remote I/O stations (such as QX40, QY40 modules) through CC-Link IE Field to achieve centralized control and data acquisition of decentralized equipment.
