MCAC806 400W 36V-80V 8A AC Servo Motor Driver Controller

MCAC806 400W 36V-80V 8A AC Servo Motor Driver Controller

The MCAC806 is a fully closed‑loop digital servo drive based on DSP vector control, designed for AC servo motors operating at 48–80 V and rated up to 400 W. It provides adjustable position, speed, and current control loops.


Features:

Multiple pulse input modes: Pulse+Direction, CW/CCW dual‑pulse, A/B‑phase pulse;

Servo reset input (ERC) with opto‑isolation

Typical bandwidth: current loop 2 kHz, speed loop 500 Hz, position loop 200 Hz;

Motor encoder input: differential signal (26LS32);

Configuration interface: RS232C for parameter download via PC or text display;

Protections: over‑current, I²t, over‑voltage, under‑voltage, over‑temperature, over‑speed, differential error;

Status indicators: green (running), red (protection/offline);

Note: Compatible with AC servo motors rated ≤400 W and supply voltages of 48–80 V.
