H5U Series EtherCAT Bus High-Performance Compact PLC
Technology introduces its first compact PLC with integrated EtherCAT bus—the H5U series, designed to enable high-speed operation for production line equipment. Addressing increasing consumer demands and manufacturing pressures, the H5U delivers four core advantages: significant reduction in wiring complexity, substantial decrease in programming and commissioning time, support for multi-axis control requirements, and alignment with strict cost-control objectives. As an innovative product integrating EtherCAT bus into compact PLCs, the H5U provides a high-performance, cost-effective solution for small to medium-sized automated production lines.
Core Advantages & Technical Highlights
Multi-axis Motion Control: Performance Comparable to Medium-sized PLCs
- Superior Axis & Slave Station Capacity: Supports up to 32-axis EtherCAT bus motion control with multiple modes including absolute/relative positioning and speed control. Can connect with up to 72 EtherCAT slave stations, meeting multi-axis coordination needs in electronics manufacturing and packaging industries.
- Rich Trajectory Control Functions: Based on PLCopen motion control instructions, enables linear and circular interpolation, electronic cam, and electronic gear functions. Supports combination of pulse axes and EtherCAT axes for complex trajectory control applications.
- Integrated High-speed I/O: Standard 4-axis 200kHz pulse output and 4-channel 200kHz high-speed input for direct servo or stepper drive control.
Multi-protocol Communication & Expansion
- Comprehensive Interface Coverage: Equipped with RS485, CAN, Ethernet, and EtherCAT interfaces. Ethernet supports ModbusTCP and socket communication; CAN port configurable with CANopen.
- Flexible Expansion Capability: 16 built-in inputs and 14 built-in outputs with expansion for up to 16 local modules including GL20 series blade-type I/O and GR10 series EtherCAT slave modules.
Efficient Programming & Maintenance
- Multi-language Programming Support: Supports ladder diagram, ST language, and SFC programming. Process instructions can be encapsulated into custom process libraries via FB/FC function blocks.
- Advanced Maintenance Features: Supports USB program backup/restoration, built-in event logging, and direct communication with Inovance IT7000 HMI. Operating temperature range of -20℃ to 60℃ for harsh industrial environments.

Installation & Operation Guidance
Q: Why does the H5U overheat in electrical cabinets?
A: Ensure vertical mounting with at least 50mm clearance above/below. Avoid horizontal installation that blocks airflow and consider cabinet fans for environments exceeding 40°C.
Q: How to resolve random I/O signal glitches?
A: Proper grounding is essential. Connect shield cables to the H5U's PE terminal and maintain 200mm separation between power and signal cables. Use 360° shield clamps for optimal performance.
Q: What causes EtherCAT communication errors?
A: Ensure EtherCAT cables don't exceed 100m per segment. Install certified terminators at the last servo and check for loose connectors, especially in vibrating environments.
Selection Tips: Choose models based on actual axis requirements. For EU/NA exports, select -INT version for certification compliance. Match expansion modules to application needs—GL10-1616ETN for digital I/O, GL10-4AD/4DA for analog signals.
