Detailed Product Description

ALL-DIGITAL  AC SERVO DRIVE

MMT-48APS08AL

Summary
MMT-48APS08AL series all-digital AC 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.
MMT-48APS08AL provide three feedback loops: position loop, velocity loop and current loop.
Three work control mode: position, velocity and torque. MMT-48APS08AL matches with AC servo motor under 80V and 400W.
Features
Position control: light isolate input PULSE/DIRECTION or CW/CCW signal;
Speed control: input simulate 0-3.3V voltage signal (speed input by P1);
Torque control: input simulate 0-3.3V voltage signal (torque input by P1);
Light isolation servo reset input interface ERC;
Light isolation servo failure alarm output interface ALM;
