A6 Series AC Servo Driver

Product Overview

The A6 series motor uses a 17-bit encoder, with 131,072 pulses per revolution, greatly improving the motor's positioning accuracy and enabling smoother operation at low speeds with smaller speed errors. It supports 17-bit absolute value encoding to prevent position loss during sudden power outages, eliminating the need for installing home switches and limit switches, which saves equipment installation time and reduces potential failure points.

Features

1. The A6 series servo driver adopts a new 32-bit digital controller, 2. with a main frequency up to 168MHz, 3. enabling a higher servo response frequency, 4. capable of meeting more application scenarios.
