Multi-axis handling robots and automated assembly lines

Automation equipment with analog control systems (needing extra I/O)

Retrofit projects of traditional analog servo systems

Usage and Maintenance

Ensure unobstructed cabinet airflow for cooling efficiency

Keep ambient temperature ≤45 °C to avoid performance derating

Complete power, feedback, and analog wiring before power-on

Configure parameters via IndraWorks per application requirements

Clean air ducts and heat sinks every 6 months; inspect terminal connections

Calibrate control loops and feedback signals annually
