3HAC9710-1
ABB 3HAC9710-1 Servo Drive Module (IRC5 Robot Controller Axis Amplifier)
Product Description
The 3HAC9710-1 is a high-performance servo drive module designed for ABB’s IRC5 robot controller, responsible for precise motion control of industrial robot axes. Its core function is to convert DC bus voltage into three-phase AC power with adjustable frequency and amplitude, driving servo motors to achieve accurate position, speed, and torque regulation—critical for applications in automotive assembly, electronics manufacturing, and material handling, where robotic movements require sub-millimeter precision (e.g., welding seam accuracy of ±0.5mm in car body production).
As a key component in the IRC5 controller’s drive system, the module operates in a multi-axis configuration, typically controlling one or two robot axes (e.g., the wrist or arm joints of an ABB IRB 6700 robot). It integrates advanced control algorithms, including field-oriented control (FOC) and proportional-integral-derivative (PID) regulation, enabling smooth motion even at high speeds (up to 200°/s for rotational axes) and rapid acceleration (up to 500°/s²), reducing cycle times in pick-and-place operations by up to 15%.
The module receives position and speed commands from the IRC5’s motion controller via a high-speed internal bus (1Mbps data transfer rate) and adjusts the motor current accordingly, with a current loop response time of ≤100µs to counteract external disturbances (e.g., payload variations of ±5kg in a packaging robot). It supports absolute encoders (17-bit resolution) for precise position feedback, ensuring repeatability of ±0.02mm—essential for tasks like circuit board component placement, where misalignment can render the board defective.
Protection features include overcurrent protection (triggered at 150% of rated current), overvoltage/undervoltage prot
