Basic parameters

Compatible motor power: This model is usually suitable for 4.0kW motor power, which can provide stable and efficient drive control for the corresponding power motor.

Rated output current: The rated output current is about 9.0A, which can meet the power demand of the adaptation motor during normal operation and ensure the stable operation of the motor.

Power Specifications:

Voltage: three-phase AC 380 - 500V, which can adapt to the grid voltage standards in different regions and has a wide range of applicability.

Frequency: 50/60Hz, compatible with different power supply frequency environments.

Overload capacity: It has a certain overload capacity, generally in a short period of time (such as 60 seconds) can withstand 150% of the rated current, and can withstand 125% of the rated current in continuous operation, which makes the inverter can still operate reliably when the motor is started or encounters short-term load fluctuations, reducing downtime caused by overload.

Output Frequency Range: Wide output frequency range from 0 - 600Hz in V/F control mode and 0 - 150Hz in VFC (vector control) mode. The wide frequency range can meet the diverse needs of motor speed in different application scenarios.

Product Description:

Control functions

Various control modes: V/F control and VFC (vector control) are supported. The V/F control mode is simple, which is suitable for general occasions with low requirements for speed regulation accuracy; VFC vector control can achieve more accurate motor torque and speed control, which can meet the application scenarios with high requirements for motor performance, such as machine tools, conveyor lines and other equipment.

Abundant running functions: with fast start, static current function, can make the motor reach the required speed in a short time; It is also equipped with a heating current function to prevent condensation of the motor at low temperatures, which can protect the motor in cold environments. In addition, the speed start function allows the inverter to be quickly synchronized with the running motor, improving the operating efficiency of the equipment.

Input/output configuration

Analog input: Equipped with 1 analog input port, it can be used to receive external analog signals (such as 0 - 10V voltage signal or 4 - 20mA current signal) to realize continuous adjustment of the output frequency, speed and other parameters of the inverter.

Digital inputs and outputs: 6 digital inputs and 3 digital outputs (including 1 relay output). The digital input can be used to receive external switching signals, such as start, stop, forward and reverse control, etc.; The digital output can be used to output the operating status signals of the inverter, such as operation, fault, alarm, etc., which is convenient for linkage control with other equipment.

Motor temperature monitoring: The TF (PTC Temperature Sensor) voltage supply and evaluation function for monitoring the motor temperature and the TH evaluation function for motor temperature monitoring are integrated. When the temperature of the motor is too high, the inverter can take protective measures in time, such as reducing the output frequency, stopping the machine, etc., to avoid damage to the motor due to overheating.
