MCDC706 Digital DC servo drive
1.Introduction
MCDC706 is all-digital DC servo drive system adopts high-performance digital signal processor (DSP) and integrated circuit, and come out to be a cost effective product with simple circuit, high integration, easy operation, and strong practicability. MCDC706 provide three feedback loops:(position loop, velocity loop and current loop). Three work control mode: position, velocity and torque. MCDC706 matches with DC servo motor under 70V and 200W.
