Delta Electronics ASD-A2-7543-U AC Servo Drive

Delta Electronics ASD-A2-7543-U AC Servo Drive is a 7.5 kW servo drive designed for PLC-controlled motion systems to precisely control servo motor speed, position, and torque. It is used in CNC machines, automated production lines, packaging systems, and robotic equipment, and maintenance teams and system integrators rely on it for replacement, system upgrades, or automation retrofits. It accepts 380–480V AC three-phase input and uses a 110V AC control power supply, supports position, speed, and torque control modes, and communicates via RS-485 (Modbus) and CANopen; it supports high-resolution encoders up to 20 bits, offers up to 300% peak overload capacity, and provides protection against overcurrent, overvoltage, overload, and overheating with forced-air cooling and a panel-mount form factor for 0°C to 50°C operation. Common replacements include Delta ASD-A2-7543-M Servo Drive and Mitsubishi MR-J4-70A Servo Drive.
