VFD inverter

Advantage:

■The output current is stable and the suppression ability is strong.

■Perfect protection function.

■Special models for parameter upload and download, one-key recovery.

■Electronic circuit short circuit protection.

Main circuit terminal description

The main circuit terminal functions are as follows, please connect correctly according to the corresponding function

Note:

Press "ESC" to enter the parameter setting state. If you press and hold "ESC" for more than 3 seconds and then release, you can only display and modify the factory value parameters when entering the special mode.

When setting parameters again, just hold down the ESC key to exit the parameter setting state and return to the standby mode.

Inverter and control card wiring

Note:

The above wiring diagram explained that only supplies the reference, take theactual product as the suandard, the diagram is subject to change without notice.

Note:

Fuling VFD 220v color is white

Fuling VFD 380v color is black

220v Advantage：

1. Two speed control modes: V/F control
2. No PG vector control (SVC): starting torque 0.5Hz up to 150%
3. 8-stage simple PLC function, multi-speed control and PID control
4. Support multiple frequency settings: digital setting, analog setting, PID setting, RS485 communication setting
5. I/O terminals can be freely programmed to combine multiple working modes according to user needs.
6. With a jump frequency control function, it can effectively suppress mechanical resonance and make the system more stable and reliable.
7. With instantaneous power-down retention function, it can avoid the impact of production due to instantaneous power failure
8. With over torque and under torque detection
9. Automatic voltage adjustment function to effectively solve the low frequency oscillation problem of high power motor
10. Provide a variety of fault protection functions: over-current, over-voltage, under-voltage, over-heat, overload, lack of equal real-time monitoring and protection to ensure safe operation
11. Built-in reactor with inverter above 37kW, which improves the power factor of the input side and improves the efficiency and stability of the whole machine.
12. 0.75~15kW built-in braking unit.

380v Advantage：

1. 10 kinds of main and auxiliary frequency sources can flexibly realize auxiliary frequency fine tuning and frequency synthesis
2. Two sets of 4-point input curves are added for analog input to make it more flexible
3. With two sets of motor parameters, it can realize switching control of two motors
4. Various encoder types are available: support differential encoder, UVW encoder, resolver, etc
5. Linear or S-curve acceleration and deceleration mode, four kinds of acceleration and deceleration time, which can be selected through terminal switch
6. Through built-in PLC or control terminal, automatic cycle switching operation of up to 16 sections of speed can be realized, and the holding time, acceleration and deceleration of each section of speed can be adjusted
7. The whole series has built-in speed tracking function, multiple speed tracking modes, and the speed of speed tracking can be adjusted
8. Torque limit and control: the "excavator" feature can automatically limit the torque during operation to prevent frequent overcurrent tripping; Vector mode can realize torque control

Scope of application:

1. Metal processing, CNC machine tools, wire drawing machines and other mechanical equipment
2. Boiler blower, induced draft fan, coal mine underground exhaust fan
3. Municipal engineering, central air-conditioning energy-saving transformation
4. For cyclones, centrifugal fans, etc
5. Circulating water pump, make-up water pump, oilfield water injection pump, oil delivery pump, music fountain
6. Paper equipment, chemical industry, pharmaceutical industry, textile industry, etc
