ABB 3HAC9710-1

Description

Introduction to the ABB 3HAC9710-1

Product Description

The ABB 3HAC9710-1 is a specific servo drive module designed for ABB’s industrial robot systems. This module is part of the drive system that controls the motion of individual robot axes. It functions as a single-axis servo amplifier, receiving motion commands from the robot controller and delivering the precise power required to drive a servo motor connected to a robot joint. The ABB 3HAC9710-1 integrates power electronics, control logic, and communication interfaces in a compact, ruggedized package built to withstand the demanding environment of a robot controller cabinet. Its performance directly affects the robot’s speed, accuracy, and smoothness of motion. As a genuine ABB Robotics spare part, it ensures perfect compatibility and restores original performance.

Product Parameters

• Product Series: ABB Robotics Drive Module

• Article Number: 3HAC9710-1

• Module Type: Single-Axis Servo Drive / Servo Amplifier

• Compatibility: Designed for specific ABB robot controller models (e.g., IRC5) and robot families (e.g., IRB 6600, IRB 7600 series). Exact compatibility must be verified.

• Output Power: Rated for a specific output current/voltage to drive a defined size of servo motor.

• Control Technology: Features high-speed current and velocity control loops.

• Feedback: Interfaces with the motor’s resolver or encoder for closed-loop control.

• Communication: Connects to the robot controller’s drive communication network (e.g., Drives Bus).

• Input Power: Accepts DC bus voltage from the main power supply unit within the controller.

• Protections: Includes safeguards against overcurrent, overvoltage, short circuit, and overtemperature.

Advantages and Features

The primary advantage of the ABB 3HAC9710-1 is its guarantee of original equipment manufacturer (OEM) performance and reliability within the ABB robot ecosystem. It ensures optimal torque control, dynamic response, and seamless communication with the robot controller. The drive is designed for high power density and efficient operation, minimizing heat generation. Its robust construction ensures reliable operation in environments with vibration and electrical noise. Using the genuine 3HAC9710-1 module maintains the robot’s safety certifications and motion performance, preventing potential issues caused by mismatched components.

Application Cases in Industry

This servo drive is used in the repair and maintenance of ABB industrial robots across various sectors. In automotive manufacturing, it would be replaced to restore precise motion in robots performing welding, painting, or assembly. Within metal fabrication, it ensures accurate path control for cutting, milling, or bending robots. For material handling applications like palletizing or machine tending, replacing a faulty drive with the ABB 3HAC9710-1 restores speed and positioning capability. It is a critical spare part for robots in the electronics, plastics, and food and beverage industries.

Comparison with Competing Products

Competing products include third-party or rebuilt servo drives for ABB robots. Unlike generic or reverse-engineered alternatives, the genuine ABB 3HAC9710-1 offers guaranteed compatibility with the robot’s firmware, communication protocols, and safety systems. Third-party drives may have variable performance, potentially leading to reduced speed, accuracy, or unexpected faults. While sometimes lower in initial cost, non-OEM parts can incur higher long-term costs due to compatibility issues, voided support agreements, and the risk of causing damage to other controller components. The ABB 3HAC9710-1 provides system integrity and peace of mind.

Selection Suggestions and Precautions

Selection of the ABB 3HAC9710-1 must be based on the exact robot controller model, serial number, and the specific axis drive being replaced. Always cross-reference the article number using ABB’s official spare parts catalog or RobotStudio documentation. Verify the drive is listed as compatible for your specific robot type. It is highly recommended to procure this part through authorized ABB channels to ensure authenticity.

Precautions:

• Dangerous Voltage: Servo drives contain high DC bus voltage that remains present even after power is off. Installation must be performed by ABB-certified robotics technicians following strict electrical safety procedures.

• The robot controller must be powered down and locked out/tagged out (LOTO) before any work begins.

• Capacitors must be allowed to discharge fully or be actively discharged according to procedure.

• Incorrect installation can cause immediate drive failure, damage to the motor or controller, and create a serious electrical hazard.

• After replacing a servo drive like the 3HAC9710-1, a motor calibration (phasing) and potentially a full robot calibration are absolutely mandatory to restore accurate positioning and avoid uncontrolled motion.

• Using non-genuine parts may compromise safety and void the robot’s warranty.
