ABB 3HAC9710-1 Robot Drive Unit - Product Introduction

Product Overview

ABB 3HAC9710-1 is an original single-axis servo drive unit, a core spare part for ABB IRC5 robot control systems. It delivers high-precision drive and motion control for joint motors of ABB industrial robots. As a key power component, it converts DC power into adjustable AC power per control commands, enabling precise trajectory movement, fast dynamic response and stable operation. This unit is fully compatible with mainstream ABB robot models including IRB 120, IRB 2600 and IRB 4600.

Core Functions & Advantages

• High-Precision Servo Control Equipped with vector control algorithm and 16-bit high-accuracy current sampling. The speed control accuracy reaches ±0.01%, and repeat positioning accuracy is within ±0.05mm. Combined with absolute encoders, it achieves micron-level positioning performance, ideal for precision assembly and welding applications.
• Excellent Dynamic Response Adopts three-loop control (current, speed, position). The command response time is less than 1ms with multi-axis synchronization error below 5ms, perfectly suited for high-speed handling and rapid assembly tasks.
• Industrial-Grade Reliability Featured with optimized heat dissipation and stable current output. It operates steadily at 0°C to 50°C, with strong resistance to vibration and dust for harsh working conditions. Built-in multiple protection mechanisms against overcurrent, overvoltage, overheating and short circuit, along with self-diagnosis and fault logging functions, effectively reduce unexpected downtime.
• Easy Installation & Maintenance Standard cabinet mounting design for direct replacement without extra configuration. Clear status indicators allow quick fault checking, greatly cutting maintenance time.
• Full Compatibility with ABB Ecosystem Seamlessly matches IRC5 control cabinets and supports EtherCAT bus communication. It connects smoothly with RobotStudio for offline programming and simulation, fitting perfectly into ABB automated production lines.
