Description

The Sanyo Machine Works STNM-DR-016B is a servo driver module in the SGNR nutrunner system family, manufactured by Sanyo Machine Works, Ltd. of Japan. It is designed to pair with the STNM-MC Multi-Controller unit for use in automated torque fastening systems. Refer to manufacturer documentation to confirm compatibility with your specific application.

The STNM-DR-016B is the driver unit responsible for controlling the servo motor of the connected nutrunner spindle, displaying fastening torque and angle data in real time during each fastening cycle, and reporting error codes when fastening abnormalities occur. The "016" designation in the STNM-DR series is consistent with a Sixteen (16) N·m torque rating, following the established naming convention across the STNM-DR driver family (e.g., STNM-DR-040B, STNM-DR-063B, STNM-DR-100B, STNM-DR-160B). The driver's power supply is divided into separate control and drive supplies, allowing setup and monitoring to continue during an E-stop condition.

When used within the SGNR system with the STNM-MC Multi-Controller, up to eight different fastening programs and thirty-two (32) independent fastening parameters can be pre-programmed per connected spindle, enabling different part models and fastening torques to be handled by a single machine. The SGNR system performs continuous process monitoring over more than forty-five (45) end-of-cycle data items and detects over fifty-nine (59) fastening error conditions.

About ACME MRO Solutions

We started ACME MRO Solutions to fix something we kept running into as contractors — plants down, parts slow, surplus listings you couldn't trust. Our goal is simple: get YOU the right component fast, with an honest description, so you can get back to running.

We describe what we see. Used items show signs of use; if a part has visible wear, damage, or a missing component, the condition description will say so. We don't claim anything is tested unless we tested it — and we don't bench-test parts where testing isn't practical or revealing (feed-through modules, breakers, mechanical components). When we do test something, we'll say so explicitly.

If something is our fault, we don't work through it — we make it right. We are proud to serve American manufacturing. Your uptime is our bottom line.
