Regenerative converter VF64R
The VF64R regenerative converter further advances the VF61R, with consideration for the power supply environment, options for system upgrades, and open network support.
Features/functionality
- Control modes: PWM sine wave converter mode and 120-degree electric current mode
- Multiple options for system upgrades
- Open network support
Customers can choose either PWM sine wave converter mode or 120-degree electric current mode (regeneration function only), whichever is best suited to the installation environment.
Super block diagram and ladder screen
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. Design/adjustment using PC tools is also supported.
Traceback screen
A variety of open networks are supported by using optional cards, allowing the construction of networks with a variety of devices, including those that output commands to converters and those that monitor converter status.
