Core Functions

Three-loop control of current, speed and position ensures stable dynamic performance under medium loads.

BE12 SERCOS fiber-optic bus realizes high-speed data transmission and precise multi-axis synchronization.

External cold technology reduces cabinet heat load, enabling smaller control cabinets.

Detachable firmware module facilitates quick replacement and data recovery during maintenance.

Modular structure supports flexible function expansion and convenient on-site maintenance.

Comprehensive protection against overvoltage, undervoltage, overcurrent, short circuit, overheating and feedback signal loss.

Supports torque, speed and position control modes for diverse medium-power motion applications.

Application Scenarios

Medium-duty CNC machine tools and precision machining centers

Multi-axis automated production lines and medium-load handling robots

Textile, printing and packaging machinery

Industrial automation systems adopting BE12 SERCOS fiber-optic bus communication

Medium-power servo system assembly and equipment retrofitting projects

Usage and Maintenance

Install the drive vertically and ensure unobstructed external airflow for cooling.

Keep ambient temperature below 45 °C during operation to avoid performance derating.

Install the firmware module correctly and complete all wiring before commissioning. Configure parameters via IndraWorks software.

Clean external heat sink and cooling air passages every 6 months, and inspect terminal connections periodically. Calibrate control loops every 2 years to maintain stable operation.

Transfer the firmware module to a new unit directly for rapid system recovery when drive replacement is needed。
