Key Features
  • Built-in Safe Torque Off (STO): Integrated STO function compliant with IEC/EN 61800-5-2 SIL2 standards ensures personnel safety during maintenance and emergency situations. Eliminates the need for external safety contactors, reducing panel space and system cost.
  • Flexible Power Input: Supports both single-phase and three-phase 200-240V AC input, making it ideal for global deployment across regions with varying power infrastructure.
  • High Response Bandwidth: Achieves 3.1 kHz speed response bandwidth with settling time reduced by up to 40% compared to previous ASDA-B2 series.
  • 24-bit High-Resolution Encoder Support: Supports 24-bit absolute and incremental encoders for exceptional positioning precision and ultra-smooth low-speed operation.
  • Advanced Auto-Tuning: Built-in auto-tuning automatically calibrates drive parameters to match load inertia and mechanical characteristics.
  • Versatile Communication: Supports MODBUS RS-485, CANopen, and EtherNet/IP for seamless integration into diverse automation architectures.
  • Energy Regeneration: Built-in regenerative energy utilization improves overall system efficiency and reduces operational costs.
