3HAC4776-1/1
Product Name
ABB 3HAC4776-1/1 Robot Axis Servo Drive Module (IRC5 Robot Controller Dedicated)
(Naming convention explanation for ABB robotics components:
- “3HAC”: Product family prefix, identifying ABB Robotics’ core control and drive modules (distinguished from “3HNE” for sensors or “3HAB” for mechanical parts).
- “4776-1/1”: Model-specific code: “4776” denotes the mid-power servo drive series; “1/1” specifies the hardware revision (Revision 1) and single-axis configuration (vs. multi-axis variants).
- Core positioning: Acts as the “motion execution unit” for ABB IRC5-controlled robots, regulating the torque, speed, and position of individual robot axes (e.g., shoulder, elbow, wrist axes) to achieve precise motion paths.
2. Product Description
The ABB 3HAC4776-1/1 is a high-precision servo drive module engineered to address robotic axis motion control challenges in manufacturing environments (e.g., automotive assembly, electronics production, material handling). As a critical component of ABB’s IRC5 robot controller ecosystem—renowned for high dynamic performance and reliability—it delivers validated value through four key capabilities:
2.1 Single-Axis Precise Motion Control
Optimized for controlling individual robot axes with ultra-low latency:
- Employs ABB’s proprietary Advanced Motion Control (AMC) algorithm to achieve ±0.01mm positional accuracy and <5ms dynamic response time—critical for tasks requiring micron-level precision (e.g., robotic welding, PCB component placement).
- Supports torque, speed, and position control modes, adapting to diverse robotic applications (e.g., torque control for assembly tasks, position control for pick-and-place operations).
2.2 Seamless IRC5 Controller Integration
Plug-and-play compatibility with ABB’s IRC5 controller reduces setup complexity:
- Connects directly to the IRC5 controller’s drive bus (ABB proprietary SERCOS III-based interface) for real-time data exchange—enabling synchronized motion across multiple axes (e.g., 6-axis articulated robots).
