Product Overview
The XQ-RS9100MB is the ultimate solution for large-scale industrial motion control and smart factory integration. As a flagship 130kg MODBUS industrial actuator, it is specifically engineered to interface directly with industrial PLCs, HMIs, and SCADA systems via the standard MODBUS-RTU over RS485 protocol.

Key Technical Highlights
1. Standardized PLC Integration (MODBUS-RTU)
Utilizes the gold standard for industrial communication, allowing seamless synchronization with factory-floor controllers without complex intermediate logic.
2. Monster 130kg Torque & 4S Efficiency
Optimized for 16.8V HV drive, producing 1805 oz-in of torque to handle massive mechanical loads with absolute precision.
3. Full CNC Armor & Industrial Socket
Full CNC aluminum case and socket interface for rapid deployment and prevention of power fade during continuous high-load industrial cycles.
Frequently Asked Questions
Yes, via the RS485 port using standard MODBUS registers for position, speed, and telemetry backread.
Higher voltage ensures lower current draw and higher efficiency for the massive 130kg torque output.
Choosing the XQ-RS9100MB for a MODBUS Cell
When the XQ-RS9100MB stands in for a stand-alone servo drive, two decisions shape the rest of the integration: how the actuator is addressed, and which pack voltage the joint runs on. MODBUS-RTU traffic stays on the RS485 port the PLC, HMI or SCADA layer already uses, so position, speed and telemetry are read as registers instead of through extra intermediate logic. The 8.4 V–16.8 V window lines up with 2S to 4S packs: 2S gives 0.20 s and 90 kg.cm, 3S gives 0.15 s and 110 kg.cm, and 4S gives 0.12 s and 130 kg.cm (1805 oz-in). Where the joint has to hold that peak load through continuous high-load cycles, 16.8 V is the sensible choice, since the higher voltage keeps current draw down and efficiency up. A 61.0 x 30 x 60.4 mm, 190 g housing that uses a full CNC aluminium case as its heatsink plus a socket interface keeps deployment quick. The closely related 130 kg.cm unit that uses a plain RS485 link rather than MODBUS is described on the XQ-RS9100D RS485 actuator page.
