Core Functions

3-loop control (current/speed/position) for high precision

DA02 upgrade: Absolute encoder emulation + enhanced analog command (vs DA01 incremental-only)

Internal convection for standard cabinet installation

Full protection: Over/undervoltage, overcurrent, short-circuit, overtemperature, feedback loss

Application Scenarios

Heavy-load CNC axes (mixed digital/analog with absolute feedback)

Textile/printing/packaging machinery with legacy analog controllers needing absolute position

Heavy gantries, conveyors, automated lines

DIAX02 retrofits requiring 150 A + absolute encoder emulation

Cabinet-space-limited equipment without external cooling

Usage & Maintenance

Ensure unobstructed cabinet airflow for cooling

Keep ambient ≤45 °C to avoid derating

Complete power/feedback/control wiring before power-on

Configure via IndraWorks (motor/load-specific)

Clean heat sinks/air passages every 6 months；inspect terminals

Calibrate loops/encoder signals annually
