Technical Specifications Three‑phase AC main power input, three‑phase AC motor output, built‑in power rectifier and IGBT inverter power stage. Multiple analog and digital I/O terminals, industrial communication interface. Operating ambient temperature 0 ℃ to +40 ℃, storage temperature ‑20 ℃ to +70 ℃, relative humidity 5%‑95% non‑condensing. Equipped with cooling fan and heat sink assembly.
Functional Features Realizes adjustable frequency and voltage output for AC motor speed control. Supports multiple motor control modes. Integrates over‑current, over‑voltage, under‑voltage, over‑temperature and motor overload protection. Provides rich digital and analog I/O for external interlock control. Supports industrial fieldbus communication for upper system connection. Stores fault history records.
Application Scenarios Industrial motor driving equipment for fans, pumps, conveyors in power plant, chemical industry, mining and manufacturing workshops.
Performance Parameters Nominal motor driving power rating, wide output frequency adjustment range, fast fault response, stable heavy‑load running capability.
Material Composition Metal main frame and protective housing. High‑power rectifier bridge, IGBT power modules. Aluminum heat sink, cooling fan assembly. Main control processing board, signal I/O terminals, bus communication components.
Structural Characteristics Vertical cabinet‑style drive unit structure. Upper section contains control board and signal terminals, lower section arranges power components and heat dissipation system. Main power input and power output terminals located on bottom area. LED status indicators and local operation keypad are placed on front panel.
Working Principle Three‑phase AC input power passes through rectifier circuit and converts to DC bus voltage. Built‑in monitoring circuit continuously detects running parameters and triggers protection action when abnormal condition occurs.
Installation Requirements Complete power wiring and control signal wiring separately, keep distance between power cable and signal cable.
Usage Notes Match drive power rating with motor nominal parameter. Ensure cooling system works normally. Do not operate without proper protective housing. Follow EMC wiring specifications for signal cables.
