RELIANCE DASR‑6 MD‑B7005B AC Servo Drive Main Board

DASR‑6 MD‑B7005B is the main control board for Reliance Electric DASR‑6 series digital AC servo drive system. It executes motion‑control algorithms, processes resolver‑encoder feedback signals, and outputs PWM drive pulses to power‑stage components. This board implements position, speed and torque loop regulation for high‑precision industrial servo‑motion equipment.

This multilayer industrial PCB adopts conformal coating for anti‑dust and anti‑interference performance. It supports serial parameter configuration and comprehensive onboard fault diagnosis. Designed for internal slot‑mount inside DASR‑6 servo drives, it delivers stable motion‑control performance for metal‑working machinery, production lines and heavy‑duty automation facilities.
