The user manual for ABB Sace BSD Series brushless servo drive (BSD Series) (MANIU23-0606 E version, effective June 2006) covers safety instructions, equipment overview, installation, wiring, test operation, parameter settings, servo adjustment, special adjustment, keyboard operation, inspection and maintenance, characteristics, specifications, and RS485 communication. It specifies the matching requirements for servo amplifiers (such as BSD0100 to BSD2000, corresponding to 100W to 2000W) and servo motors (such as BSM0100 to BSM2000), emphasizes safety operating standards (such as waiting for 5 minutes after power failure before wiring, correct grounding to prevent electric shock), equipment installation environment (such as servo motor storage temperature -20 ° C to 60 ° C), ° C, servo amplifier operating temperature -10 ° C to 55 ° C) Parameter configuration methods (such as control mode switching parameter # 09, automatic tuning parameter # 05) and troubleshooting (such as overload, overcurrent and other alarm handling) provide guidance for the full lifecycle operation of the equipment.
Core positioning: ABB AO2000-LS25 is a modular laser gas analyzer that operates in conjunction with the AO2000 integrated analysis system. It is based on tunable diode laser absorption spectroscopy (TDLAS) technology to measure gas concentration and only detects free molecules in the gas, insensitive to bound molecules.
The development of power semiconductors has always been aimed at pursuing the "ideal switch", which requires the characteristics of low pass state and commutation loss, high commutation frequency, and simple driving circuit. In the low-voltage field, the technological iteration from transistors and Darlington transistors to IGBT (Insulated Gate Bipolar Transistor) has achieved significant results. However, in the medium to high voltage field, the long-term dependence on GTO (Gate Turn Off Thyristor) poses problems such as complex control and limited performance.
To solve this dilemma, ABB Switzerland is exploring a new research and development path aimed at integrating the high-power advantages of IGBT with the core strengths of GTO, ultimately developing GCT (Gate Commutated Thyristor) and further developing it into IGCT, becoming an ideal alternative technology for GTO.
Application scenario: Designed specifically for on load tap changers in distribution substations, the secondary voltage of the transformer is regulated by controlling tap changers to ensure stable load voltage and adapt to 50/60Hz power grids;
Core value: Supports independent voltage regulation of a single transformer and parallel operation of multiple transformers, with functions such as line voltage drop compensation, overcurrent/undervoltage lockout, overvoltage detection, etc., to meet the stability requirements of industrial power supply;
Module composition: It consists of an automatic voltage regulation module (SPCU 1D50), a manual voltage regulation module (SPCN 1D56), a power module (SPGU 240 A1/SPGU 48 B2), an I/O module (SPTR 6B32), and a motherboard. It supports fiber optic serial bus communication (requires SPA-ZC series bus modules).
