3 Reasons the New M1 VSD Stands Out
• Standard (STD): Modbus RTU built in for cost effective control
• EtherCAT (ECT): EtherCAT with FSoE safety onboard for real time networking, STO to SIL3 /PL e
• EtherNet Multi Protocol (EMP): EtherNet/IP, PROFINET, and Modbus TCP built in
• No additional option cards required across all three variants
• Slim frames from 68 mm W × 127 mm H at the low end
• Supports induction motors, permanent magnet motors, direct drive PM motors, and special motors such as drum motors
• Supports ring topologies in EtherCat models
• 24 VDC control power backup keeps communication and control alive during mains power dips
• V/f and vector control (open & closed loop)
• Torque, speed, and position control with electronic gearing
• Built in encoder / pulse counter and energy saving functions
• Single software for setup, tuning, and monitoring
• Up to 200% torque at 0.5 Hz
M1 Variable Speed Drive vs Competitors
| Area | OMRON M1 Drive Series | Typical Compact Drives |
| Networking | Built in by model (Modbus, EtherCAT, or Ethernet Multi‑Protocol) | Usually limited; others need option cards |
| Safety | STO as standard; FSoE integrated on EtherCAT models | Often external or optional |
| Integration effort | Faster setup with native communications and one software tool | More wiring, add‑ons, and tools |
| Cabinet space | Slim design from 68 mm wide | Larger, less consistent footprints |
| Motor & control flexibility | IM & PM motors with speed, torque, and position functions | Typically IM only, speed control |
| Scalability | One drive series across machine architectures | Multiple drive families often required |
