Brief: This video provides a detailed walkthrough of the SIGMA BG202-XM-II Elevator Door Drive Controller. You'll see how this compact VVVF inverter ensures reliable operation for both car and landing doors, supporting permanent-magnet and asynchronous motors. We demonstrate its plug-and-play replacement capability for LG-Sigma lifts and explore key features like self-learning, RS485 communication, and field-programmable door speed settings.
Related Product Features:
  • Compact VVVF inverter designed for elevator car and landing door drive and position control.
  • Supports both permanent-magnet synchronous motors (PMSM) and 3-phase asynchronous motors up to 0.75 kW.
  • Offers plug-and-play replacement for LG-Sigma, Besta, and ThyssenKrupp S200/S300 elevator models.
  • Features sensor-less vector control (SVC) with optional encoder support for precise motor management.
  • Includes built-in self-learning, auto-reopen, obstruction re-open, and fire-emergency input functions.
  • Equipped with RS485 Modbus-RTU communication for seamless integration and monitoring.
  • Field-programmable door speed from 0.1 to 1.0 m/s and opening width from 700 to 2400 mm.
  • Provides comprehensive protection against over-current, over-voltage, under-voltage, short-circuit, and thermal issues.
Faqs:
  • Which elevator models is the BG202-XM-II controller compatible with?
    The BG202-XM-II is designed for plug-and-play replacement and is compatible with LG-Sigma, Besta, and ThyssenKrupp S200 and S300 elevator models, directly replacing older versions like BG202-XM, BG202-XM-I, and BG202-OT31C without needing parameter reloads.
  • What types of motors does this door drive controller support?
    It supports both permanent-magnet synchronous motors (PMSM) and 3-phase asynchronous motors with a power rating of up to 0.75 kW, providing flexibility for various elevator door systems.
  • What communication interface does the BG202-XM-II offer for system integration?
    The controller includes an RS485 interface with Modbus-RTU protocol, enabling easy communication and integration with elevator control systems for monitoring and configuration.
  • Are there any built-in safety or operational features?
    Yes, it features built-in self-learning for setup, auto-reopen and obstruction re-open functions for safety, and a fire-emergency input to comply with safety standards, along with protections against over-current, over-voltage, and thermal issues.
