Variable-frequency Inverter Product Description

Variable-frequency Inverter Product Features

Intelligent IGBT module heat protection design

• Built-in dynamic junction temperature model, Monitor IGBT junction temperature in real time.
• Unique short-circuit and circuit through protection technology, protect system security.
• Delay overcurrent protection reset, suppress overcurrent

Adaptive IGBT drive control stability design

• Reliable self-developed IGBT module stability design platform.
• Able to obtain main parameters in the IGBT open/close process, to evaluate the function and performance of IGBT drive board.
• Able to evaluate the reasonableness of IGBT module design, to ensure the design of product power system is safe and reliable, guarantee the stable operation of power system.

Powerful PC tools – HVManager, provide programming, setting, debugging, monitoring and other functions

• Monitor the VFD status in real time.
• Comprehensive parameter setting function, easy to debug by user.

All series have built-in EMC filter (user can choose)

• User can discocnnect EMC filter by the short sheet in the image, mainly used in the situation which require the installation of RCD and the leakage current lower than 30mA.

Function modular design, has both advantages of European models and Japanese models

• Easy to setting like Japanese models, also has strong functional expansions like European models.

• Dual RS485 interface, optional A, B interface and RJ45 interface

4kW and above models are configured DC reactor as standard

• Decrease 50% of current distortion rate.
• Inhibit impact from grid, protect rectifier bridge.
• Increase the power factor of input side.
• Increase the overall efficiency and heat stability of the VFD.
• Inhibit the effect from higher harmonics of input side to the VFD, decrease external transmission and radiation interference.

Profibus communication

• Convenient communication setting.
• Good environmental adaptability.
• Support five PPO data communication format (PPO1 ~ PPO5).

Built-in powerful logic and arithmetic modules, support custom DIY for special functions

• Built-in simplified PLC, control terminals can be customize, user can design operation mode according to his special requirement.

Can set DI terminals leakage and source mode by function code

• DI input common port can choose 0V or 24V, the factory default value is 0V, user can select by setting parameter P09.21; P09.21 = 0 means the common port is 0V, P09.21 = 1 means the common port is 24V.

Built-in PID control module

• Realize the close loop control of temperature, pressure, flow and other signals, increase the stability and accuracy of production.

Can drive two different motor in vector control mode

• Can store two sets of motor parameter, and can switch flexibility in the situation which need not to run two motors in the same time, to save the cost, reduce the space occupation.

Typical Application

Oilfield pumping unit

• Technical advantage: Wide voltage range, strong adaptability to harsh grid Low starting current, smooth speed, small impact to grid Built-in EMC filter, standard configured DC reactor, low radiation.

Steel plant cold saw

• Technical advantage: High overload ability, high speed response ability. Adapt to high temperature and high protection requirements in steel workshops. Support Profibus DP network.

Steel plant roller

• Technical advantage: Adapt to reciprocating acceleration and deceleration operation. Long - term continuous operation. Adapt to high temperature and high protection requirements in steel workshops Support Profibus DP network.
