BE12: Pre-configured SERCOS + safety I/O (reduces integration effort)

Internal cooling saves cabinet space for dense multi-axis layouts

Comprehensive protection: over/undervoltage, overcurrent, short circuit, overheat, feedback loss

Torque/speed/position control modes

Modular design for easy maintenance/upgrades

Application Scenarios

Medium-power CNC machine axes (with safety requirements)

Textile/printing/packaging machinery (multi-axis sync + safety)

Automated assembly lines & handling robots (SIL2/Cat.3 safety)

Automation requiring SERCOS real-time communication + safety

DIAX03 system upgrades with enhanced safety I/O

Usage and Maintenance

Ensure unobstructed cabinet airflow (maintain cooling efficiency)

Keep ambient ≤45 °C to avoid performance derating

Complete power/feedback/control wiring before power-on

Configure via IndraWorks (match motor/load parameters)

Clean air passages/heatsinks every 6 months; inspect terminals

Calibrate control loops/feedback annually for stability
