Configured for high-speed deterministic motion execution and database connectivity in industrial automation networks, the Omron NX701-1720 (NX701-1720 Motion Controller NX7) provides direct physical/electrical execution.

Controller Architecture & Processing Matrix

The unit delivers core controller functionality encompassing database connection, motion control, OPC-UA, and sequence logic processing. Operating on a primary task cycle time of 0.125 ms, it features 80 MB of program memory and 260 MB of variables memory. The system manages up to 256 synchronous and virtual motion axes concurrently across the high-speed NX I/O bus infrastructure.

Hardware Specifications

Deterministic Network & Backplane Performance

Backplane bus communication velocity and firmware flash compatibility ensure real-time data exchange across connected servo drives and remote nodes. Deterministic networks are maintained via integrated EtherCAT Master, EtherNet/IP, and Ethernet TCP/IP communication ports. I/O density scaling allows seamless expansion without introducing jitter into the sub-millisecond motion task loop.

Mechanical Mounting Guidelines

• Mount the controller vertically onto a standard 35 mm DIN rail inside a ventilated control cabinet to maintain thermal limits.
• Ensure a minimum clearance of 50 mm above and below the module housing for natural convection airflow.
• Torque DIN-rail end stoppers securely on both sides of the base to prevent shifting under heavy machine vibration.
• Route high-voltage power lines and low-voltage communication cables through isolated wire trays to eliminate electromagnetic interference.
