VFD Control Cabinet

Thank you for choosing DEPUMP® high-performance vector control inverter independently developed by our company.

Vfd control cabinet high-performance vector control inverter uses advanced flux vector control technology, the motor parameters are still not sensitive to the premise of the high-performance motor control. With full frequency, high torque output and fast response, excellent load compatibility, high speed control accuracy and good reliability, it is ideal for high performance general purpose inverters that truly meet the high field requirements.

Vfd control cabinet high-performance vector control inverter is the general needs of customers and industry needs an organic combination of products, to provide customers with a practical PID regulator and constant pressure water supply, simple PLC, programmable input and output terminal control, remote synchronization control , The pulse frequency given and other special inverter control and other powerful features for the equipment manufacturing and automation engineering to provide our customers with high integration of integrated solutions to reduce system costs and improve system reliability with high the value of.

This manual has some guidance for the user's equipment installation,
operation parameter setting, abnormal diagnosis, routine maintenance and safe use. For proper installation and operation of this series of products, please read this manual thoroughly before using the A600 high performance vector control inverter.

  Parameter  

Inverter wiring part of the vfd control cabinet,divided into main circuit and control circuit. The user can lift the cover of the output / input terminal, at this time, the main circuit terminal and the control circuit terminal can be seen. The user must
connect the circuit correctly according to the following figure.

  Main circuit terminal wiring  

  Regular maintenance  

According to the use situation, the user can perform a regular routine inspection on the inverter for a short time or 3 to 6 months to eliminate the hidden troubles and ensure long-term high-performance and stable operation.

Vfd control cabinet 160KW routine inspection content:
1) If the control terminal screws are loose, tighten them with a suitable size
screwdriver.
2)Whether the main circuit terminal has poor contact, whether there are traces of overheating on the cable or copper row connection, screws, etc.

3) Whether the power cable or the control wire has any damage, especially whether the external insulation layer has cracks or cuts.

4) Whether the connection between the power cable and the cold-pressed
connector is loose, and whether the insulation wrap around the connector is aging or falling off.

5) Clean the dust on printed circuit boards, air ducts, etc., and take precautions
against static electricity when cleaning.

6)For the insulation test of the inverter in the vfd control cabinet, all wirings between the inverter and the power supply and between the inverter and the motor must be removed first, and all the main circuit input and output terminals must be reliably short-circuited after the conductors are tested, and then tested on the ground. Please use a qualified 500V megger (or corresponding voltage file of the insulation tester); do not use a faulty meter. It is forbidden to connect only a single main circuit terminal to conduct insulation test on the ground. Otherwise, there is a danger of damaging the inverter.
Do not perform insulation tests on the control terminals. Doing so will damage the inverter. After testing, it is important to remove all wires that are shorted to the main circuit terminals.

7) If the motor is tested for insulation, the wires connected between the motor and the frequency converter must be completely disconnected and the motor must be tested separately. Otherwise, there is a danger of damaging the inverter.
