Delta ASD-A2-1F23-F ASDA-A2 DMCNET Servo Drive Unit

Module Feature

ASD-A2-1F23-F is Delta ASDA-A2 series high dynamic servo drive with DMCNET communication interface, rated 15kW, three-phase 220VAC input.

It supports PR internal position command, pulse command, analog speed/torque control, full closed-loop feedback function. Built-in E-CAM electronic cam with up to 720 cam points, dedicated for flying shear and rotary cut applications. Auto notch filter and vibration suppression algorithm reduce mechanical resonance. Gantry synchronous control, high-speed capture and compare function are integrated. 1kHz speed response bandwidth, matched with 20-bit high-resolution absolute/incremental encoder. DMCNET high-speed bus realizes multi-axis synchronous linkage. Fan cooling, DIN rail cabinet installation. Widely stocked spare for printing, packaging, film cutting and CNC machine tool motion cabinet.

Working principle

Three-phase AC power is rectified to DC bus, DSP core outputs PWM pulse to IGBT power stage to drive servo motor.

Position loop, speed loop and torque loop run independently. It reads encoder feedback signal for closed-loop regulation; full closed-loop mode can receive external linear scale signal. DMCNET bus receives synchronous command from upper controller. Continuous self-monitoring captures overcurrent, overvoltage, overtemperature, encoder disconnection and bus communication fault, locks fault code and stops output safely.

Onboard components

IGBT power module, DC bus capacitor bank, Hall current sensor, DSP control core, DMCNET communication chip, encoder differential receiving circuit, vibration suppression processing unit, cooling fan, status LED bank and metal chassis.

LED indicators

Front panel LEDs indicate power, servo ready, running, alarm fault status; digital keypad displays operating parameters and fault codes.

Hardware self‑diagnosis

Built-in supervision detects overcurrent, DC bus over/under voltage, heatsink overtemperature, encoder signal loss, DMCNET communication timeout and hardware anomaly. Configuration and fault diagnosis are completed by Delta ASDA-Soft software.

Programming softwareASDA-Soft, used for motor auto-tune, cam curve editing, filter setting, DMCNET axis mapping and fault history reading.
