- Compact Size: Smallest model measures just 80×90×75mm for flexible installation in space-constrained scenarios
- Maintenance-Free Design: Data persistence technology eliminates backup batteries, IP20 protection rating for dust and moisture resistance
- Global Compatibility: -INT models passed CE, UL, UKCA, RCM and EAC certifications, wide voltage design (AC 100-240V)
Technical Highlights
- High-Speed Motion Control: Standard 3-axis 100kHz high-speed pulse output, basic instruction execution speed of 0.26μs/step
- Compatible Ecosystem: AutoShop programming software compatible with Mitsubishi syntax, USB offline download support
- Multi-Protocol Networking: 2 independent serial ports (485/422) + USB interface, compatible with Modbus and CANlink 3.0
- Flexible Expansion: Seamless connection with H2U series remote modules, expanding I/O points from 14 to 60
- Strong Anti-Interference: Passed 4kV electrostatic discharge and 10kV surge impact tests, wide operating temperature range (-10℃~60℃)

Common Installation & Operation Issues
Q1: PLC frequently reports errors and trips in Southeast Asian workshop
Likely due to unstable power grid voltage. Measure voltage with multimeter, add voltage stabilizer if fluctuation exceeds ±15%. Check for terminal oxidation in humid environments.
Q2: Program lost after power outage in African factory
Equip with small-capacity UPS backup power supply. Ensure "Permanent Program Storage" is checked during initial program download.
Q3: Communication fails with local HMI in Europe
Change PLC serial port mode to slave in programming software. Use shielded twisted-pair cables with proper grounding.
Q4: Positioning inaccurate when driving stepper motor in Mexican factory
Check pulse wire length (max 20m), verify motor subdivision parameters match PLC pulse counts. Use shielded cables away from power cables.
