Core Functions

Current/speed/position three-loop control for stable low-power motion

BE12 dual-interface: SERCOS for bus control + resolver for harsh-environment feedback

Internal cooling saves cabinet space, ideal for 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 basic automation tasks

Application Scenarios

Low-power CNC machines with resolver feedback

Multi-axis packaging/printing machinery requiring SERCOS synchronization

Textile machinery with rugged resolver position control

Robotics/handling systems with compact cabinet layouts

Medium-to-low power servo retrofits with BE12 interface

Usage and Maintenance

Install with adequate cabinet ventilation for internal cooling

Operate below 45 °C to avoid performance derating

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

Wire SERCOS fiber and resolver cables correctly to BE12 interface

Clean internal air passages every 6 months; inspect terminals periodically

Calibrate control loops and resolver feedback every 2 years
