Core Functions
Three‑loop control (current/speed/position) for high‑precision motion
Torque, speed, position control modes for diverse conditions
SERCOS interface for real‑time data and multi‑axis synchronization
Integrated holding brake control and regenerative braking management
Full protection: Overvoltage, undervoltage, overcurrent, short circuit, overheating, feedback loss
Auto‑parameter matching for MKD/MSK/MHD motors
Built‑in homing, jogging, point‑to‑point positioning
Application Scenarios
High‑precision CNC machine tools, machining centers, engravers
Packaging, printing, textile, plastics machinery requiring high dynamics
Automated assembly lines, handling equipment, multi‑axis robots
380–480 V AC single‑axis systems needing high precision
ECODRIVE 02 series retrofit projects
Usage and Maintenance
Mount vertically; ≥80 mm clearance top/bottom for airflow
Separate power/signal cables; use shielded encoder cables (single‑end ground)
Clean fan/filters every 3–6 months in dusty environments
Check terminal tightness and cooling paths regularly
Load FWA firmware and set parameters via IndraWorks/DriveTop
Avoid frequent power cycling; disconnect power for long‑term shutdowns
