The ABB ACV 700 Frequency Converters have technical specifications including frequency of 50 Hz or 60 Hz ± 3%, fundamental power factor of 0.97 - 0.99, total power factor of 0.93 - 0.95 (theoretical maximum), and efficiency at rated power > 98%. It has various motor connection parameters, load capacity details, switching frequencies for IGBT - and GTO - inverters, field weakening set - point ranges, acceleration and deceleration times. The enclosure has protection degrees and paint colours, with environmental limits for stationary use, storage, and transportation. Electrical and safety parameters are also specified. The control system APC is flexible, compact, and efficient, programmed with function blocks, can handle unstable + 24 VDC voltage, and has multiple communication buses like AdvantFieldBus 100, RS - 485, PC - Link, and a drive link. There are standard I/O signal connections. The power supply section is composed of different parts for different power ranges, and the drive section has different power stage types (IGBT or GTO) applicable to different power ranges with details on structure, parameters, and control principles.
Drive section
Power stage type: based on IGBT or GTO power stage, different types are applicable to different power ranges; IGBT power stage is applicable to part of the lower power range, GTO power stage is applicable to the higher power range.
Structure and parameters: the main components of the inverter unit, such as IGBT module, GTO, etc.; the size, weight, overload capacity, cooling requirements and other parameters of different types of drive units are given, as well as the control principle and requirements for the use of parallel inverter units.
