Basic parameters

Applicable motor power: 4.0kW.

Rated output current: Approx. 8.5A.

Power specification: three-phase AC 400 - 500V, power frequency 50/60Hz.

Overload capability: typically 150% of the rated current for short periods of time (e.g., 60 seconds) and 125% of the rated current for continuous operation.

Output Frequency Range: 0 - 600Hz in V/F control mode; 0 - 150Hz in VFC (Vector Control) mode.

Product Description:

Control function: Support V/F control and VFC vector control. It has the function of automatic identification of motor parameters, relying on the mathematical model of the motor, it can automatically identify the stator impedance, mutual inductance, magnetic saturation factor, inertia and other parameters of the motor, and calculate the actual torque, stator flux and rotor speed for real-time control. Band-to-Band control can also be realized, and PWM signals are generated by Band-Band control of flux and torque to control the inverter switching state.

Input/output configuration: There is 1 analog input port for receiving external analog signals to adjust parameters such as output frequency. 6 digital input ports, which can receive control signals such as start, stop, forward and reverse; 3 digital output ports, 1 of which is a relay output, for outputting operating status signals. Integrated TF (PTC Temperature Sensor) voltage supply and evaluation function and TH evaluation function for motor temperature monitoring.

Protection function: It has a variety of protection functions such as overcurrent protection, ground fault protection, overload protection, inverter overheating protection, motor overheating protection, etc. It has multiple error memories to record the operating data at the time of error occurrence and facilitate troubleshooting.

Mechanical characteristics and design: modular, compact design, compact structure, small size, saving control cabinet installation space, easy to install, debugging and maintenance. It can adapt to harsh industrial environments with an ambient temperature rating of up to 50 degrees. The integrated EMC line filter reduces electromagnetic interference and meets the different limits specified in EN 61800 - 3.

Communication and expansion: Communication connection with host computer or other equipment can be realized through optional communication modules (such as FSC11B, FSC12B, FSE24B, etc.), and a variety of communication protocols (such as Modbus, CANopen, etc.) are supported. Input/output expansion is allowed, and additional input and output ports can be added according to actual needs to meet more complex control requirements.
