Basic electricity and physical parameters
Core power specifications: Rated output power of 7.5kW, corresponding to 10 horsepower, rated output current of 18A, with overload capacity of 150% rated current for 1 minute, capable of handling short-term load peaks in industrial scenarios. Input compatible three-phase 380-480V AC voltage, in compliance with industrial three-phase power supply standards; The protection level is IP20, suitable for the conventional dust-proof installation environment inside the control cabinet, with a working temperature range of -10 ℃ -+40 ℃ and a storage temperature range of -20 ℃ -+60 ℃, suitable for most industrial temperature and humidity environments.
Physical installation dimensions: The external dimensions are 200mm × 323mm × 183.2mm, with a total weight of approximately 10kg. The dimensions are consistent with the 5.5kW model of the same series, and the installation compatibility is strong, making it easy to plan and layout in industrial control cabinets.
Core control performance parameters
Frequency regulation capability: The output frequency can be accurately adjusted between 0.1-400Hz. If there are special requirements, it can also be extended to 2000Hz high-speed output through factory programming. The adjustment range of acceleration and deceleration time is 0.1-3600 seconds, which can be flexibly set according to the start stop characteristics of the equipment to avoid impact loads during startup or shutdown; Simultaneously supporting adjustable V/F curves, it can adapt to the speed torque requirements of different types of motors.
High performance control mode: The core supports sensorless vector control and V/F control, which can achieve constant torque output and ensure the smooth operation of the equipment. Its starting torque performance is excellent, reaching 150% of the rated torque at 1Hz, which can easily drive heavy-duty equipment to start; It also supports flexible switching between primary/secondary frequency sources and first/second frequency sources, adapting to complex control logic.
Multi stage speed control: Equipped with 16 stage speed control and 15 stage preset speed program operation functions, it can directly achieve automatic speed switching of multiple processes through parameter settings without the need for additional controllers, adapting to multi working conditions such as assembly lines and machine tools.
Practical functions and safety protection parameters
Automation auxiliary function: Built in PID feedback control function, which can be directly used for flow and pressure closed-loop regulation of pumps, fans and other equipment; Equipped with automatic torque boosting and slip compensation functions, it can reduce the impact of load fluctuations on motor speed, ensure the stability of equipment speed under different loads, and also have sleep/wake-up functions, which is conducive to energy conservation and consumption reduction.
Comprehensive safety protection: Supports DC injection braking and dynamic braking. The braking unit can be equipped with external components as needed to enhance safety and stability during shutdown. In addition, it can monitor and protect against overcurrent, overvoltage and other faults during operation, avoiding equipment damage due to electrical faults; The zero speed hold function can also prevent equipment from accidentally moving under specific operating conditions.
