Yaskawa NX100 Series Technical Notes

The Evolution of NX100 Architecture

The NX100 controller architecture is built around a VME-bus backplane with a proprietary Yaskawa communication protocol (MECHATROLINK-II on motion axes). It replaced the XRC's older ISA-based architecture with a more modular, rack-mounted card cage design. The CPU board (JANCD-NCP01) manages task scheduling and interpolation, while dedicated I/O boards (JANCD-NIO01, JANCD-NIO02) handle field-level signal interfacing. Power distribution is managed by the JZRCR-NTU01D-1 and related PSU boards, which convert incoming AC supply to regulated DC rails (+5V, ±15V, +24V) for the backplane and servo amplifier logic.

The NX100 was succeeded by the DX100 (circa 2008) and subsequently the DX200 and YRC1000 platforms. However, the NX100 remains in active service at facilities where the capital cost of controller migration is prohibitive. Compatibility between NX100 and DX100 modules is limited; most boards are not cross-compatible due to differing backplane pinouts and firmware architectures. This makes sourcing genuine NX100 spare parts a critical operational requirement for maintenance teams.

Quality Control for the NX100 Range

NX100 modules present specific test challenges due to the VME backplane architecture and proprietary MECHATROLINK-II communication protocol. DriveKNMS applies the following test procedures to all NX100 boards prior to dispatch:

All tested units are issued a DriveKNMS inspection report with test date, technician ID, and measured parameters. Units that do not meet specification are quarantined and not offered for sale.
