3. Modular design, common DC bus scheme.
4. Rich extension interfaces to meet all customer needs.
5. Multiple fault handling and protection methods, safe and stable.

Built-in multiple function modules

Debugging host computer adapted to working conditions

1. VCSoft debugging software.
2. The graphical interface menu-style operation can complete the simple configuration, parameter setting, fault detection, system maintenance, and service of the complex system in a short time.

Multi-function keyboard

1. LCD display screen.
2. Support Chinese and English languages.
3. Through the built-in Bluetooth of the keyboard, simple and convenient debugging of handheld devices can be realized.
4. Parameter copy and restore.

Modular design

1. Filtering, rectification, inverter and braking are all independent and standard modules.
2. The book-type design is convenient to form a cabinet and reduce the size of the cabinet.
3. The module can be flexibly configured according to the power of the load motor.

Common DC bus

1. In applications such as regenerative load lowering or winding and unwinding, the generated energy and electric energy between the inverter modules are exchanged through the DC bus to save energy requirements (5%-30%).
2. Effectively reduce the current of the rectifier module and brake module, simplifying the system capacity.
3. Unified power supply by the rectifier unit, reducing the amount of the main circuit switching devices and braking units.
4. Reduce the difficulty and amount of wiring of the electronic control system, and save user costs.

Supports multi-module parallel, the maximum extended power is 5600kW

The busbars share direct current and use V8 units for parallel operation. The 400V system supports a maximum of 2800kW, and the 690V system supports a maximum of 5600kW.

Full coverage of the main controller VCU

1. Data interconnection between the VCU control unit and each module.
2. Optical fiber communication, strong anti-interference ability.

Support a variety of expansion modules

Bus adaptation according to usage requirements.

Multiple fault handling and protection methods, safe and stable

1. Inverter protection: Short circuit, overcurrent, overvoltage.
2. undervoltage, phase loss, overheating, overload, encoder disconnection, etc.30 kinds of settings protection and multi-level classification.
3. Functional safety protection: Standard STO-Safe Torque Off function.
4. Hardware detection, disconnect the motor power by blocking the drive pulse, prevent the motor from starting accidentally, and ensure the safety of personnel and equipment.
5. Motor protection: Support PT100 temperature detection protection.
6. Black box: Standard SD card, can store multiple waveform data before and after the fault within a specified time.
7. Fuse protection: When a unit fails, it is quickly protected by the fast-acting on the bus side.
8. Module exit mechanism: When a certain unit fails, it can be withdrawn online, and the system will run with derating.
9. Quick change: There is no need to replace the VCU control unit, no need to set parameters, quickly restore the system operation, and the faulty unit can be repaired within 30 minutes.

Multi-machine transmission + parallel high-power, to meet a variety of engineering transmission applications
