VEICHI - SD860

The SD860 system represents Veichi’s new generation of modular servo drives, designed for highly integrated applications such as machine tools, automation lines, robotics, and production systems.

The multi-drive architecture allows sharing of a common DC bus and a single rectifier unit, reducing energy consumption by up to 30% and panel footprint by more than 60% compared to stand-alone systems.

Each SD860 module features PWM sinusoidal vector control with IGBT technology and supports 17- to 24-bit absolute encoders, resolvers, sine/cosine encoders, and BISS-C interfaces. Axis synchronization is achieved via EtherCAT or Profinet industrial buses operating at 100 Mbps, with centralized parameter management and simultaneous download for multiple modules.

The product range includes single- and dual-axis modules (up to 24 A per module) and spindle units up to 7.5 kW, all configurable on a single backplane with forced-air cooling and IP20 protection. The system integrates STO SIL3 safety, built-in diagnostics, alarm logging, and a USB Type-C interface for direct debugging. When paired with V7E motors (380 V AC, up to 7.5 kW), the SD860 forms a modular, synchronized servo platform suited for centralized architectures.

The common DC bus design and optional rechargeable battery module minimize maintenance downtime and optimize energy regeneration in high-frequency dynamic cycles.
