Basic power parameters
Core power and current: Rated output power of 3.7kW, corresponding to 5 horsepower, rated output current of 8.5A, with overload capacity of 150% rated current for 1 minute, capable of handling short-term load peaks. Input suitable three-phase voltage of 380-480V, in line with industrial three-phase power supply standards.
Physical installation dimensions: The external dimensions are 150mm × 260mm × 160mm, and the compact size design facilitates installation inside industrial control cabinets, saving equipment layout space.
Core control performance parameters
Frequency regulation capability: The factory default maximum operating frequency is 60Hz, and the setting range can be expanded to 50.00-400.00Hz. Some channels indicate that their maximum output frequency can reach 800Hz, which can adapt to the needs of high-speed operating equipment; Support frequency hopping settings to avoid device resonance intervals and ensure smooth operation.
Multi control mode: supports two core modes: V/F control and vector control, and can be optionally equipped with a PG card to achieve V/F control or vector control with PG, improving speed regulation accuracy; Linear acceleration and deceleration, automatic acceleration and deceleration, and S-curve acceleration and deceleration modes can also be set. The acceleration and deceleration time adjustment range is 0.1-3600.0 seconds, and the time unit can be accurate to 0.01 seconds.
Frequency and command source: The first frequency command source can flexibly choose digital operators, external terminal analog signals (such as AVI signals of 0-100V, ACI signals of 4-20mA, etc.), or RS-485 communication inputs; The source of operation instructions can also be switched between digital operators, external terminals, and RS-485 communication to adapt to different control scenarios.
Auxiliary functions and protective parameters
Operation auxiliary function: equipped with 16 preset speeds and 15 program operation functions, meeting the requirements of multi process automation control; Built in PID feedback control, suitable for closed-loop regulation of flow and pressure conditions such as pumps and fans, while supporting automatic torque and slip compensation to reduce the impact of load fluctuations on speed.
Comprehensive protection configuration: supports multiple electrical protections such as overcurrent, overvoltage, and overheating, and can also monitor radiator temperature and achieve overheating warning; The motor parking mode can be selected from deceleration braking, free running, and other modes, combined with DC injection braking to enhance the safety of parking; Simultaneously equipped with parameter protection function, it can set password to lock parameters and prevent misoperation.
Display and detection: The multifunctional display screen can display various data such as output frequency, current, voltage, power, radiator temperature, etc; Support parameter reset function, which can restore parameters to factory settings of different voltage standards, facilitating debugging and fault recovery.
