Core Functions

Current/speed/position three‑loop control for high dynamic stability

BE37 dual‑interface design: SERCOS for bus control + gearwheel encoder for redundant position feedback

External cooling reduces cabinet thermal load, supporting compact enclosures

Modular architecture enables flexible expansion and fast maintenance

Comprehensive protection: overvoltage, undervoltage, overcurrent, short circuit, overheating, feedback loss

Supports torque/speed/position control modes for complex motion applications

Application Scenarios

High‑precision CNC machine tools with dual‑encoder positioning

Multi‑axis automated lines requiring SERCOS synchronization + gearwheel feedback

Printing, textile, and packaging machinery with redundant position control

Automation systems using BE37 combined communication/feedback interface

Medium‑power servo system retrofitting with dual‑feedback requirements

Usage and Maintenance

Install vertically and ensure unobstructed external cooling airflow

Operate below 45 °C to avoid performance derating

Insert firmware module (DSM02.3‑FW) into slot U5 before commissioning

Wire SERCOS fiber and gearwheel encoder cables correctly to BE37 interface

Clean heat sink and air passages every 6 months; inspect terminals periodically

Calibrate control loops and dual feedback channels every 2 years

Transfer firmware module to replacement unit for rapid system recovery
