Advanced-function, high-capacity, water-cooled inverter/converter VF64(R)HPW

高機能・大容量・水冷式Inverter・コンバータVF64(R)HPW

This 1,000 kW max inverter/converter uses a high-capacity IGBT and achieves high capacity in a small space by employing water-cooled design.

Features/functionality

Unit configuration

Each unit is 250 kW for up to 1,000 kW when four are connected in parallel. Performing current balance control between units connected in parallel eliminates the balance reactor, and a compact size has been enabled by the use of a high capacity IGBT and water-cooling.

Built-in HC function and sequence function

The HC function implements high-speed operations by combining approximately 30 super blocks that use a high-speed CPU for high-precision, high-response control of motor drive. The sequence function enables the building of approximately 100-step ladder programs within the inverter.

Support using PC tools

Monitoring of operation status and data collection are possible by utilizing the traceback/trend function, enabling precise engineering that quickly responds to system construction. Settings can be easily changed, exported, and copied using a PC.
