Product Introduction
Bonfiglioli VCB400-060 is a 30 kW three-phase frequency inverter in the VCB series. It provides speed, torque and position control for asynchronous motors in industrial applications requiring reliable vector performance.
The unit accepts 400 V mains, delivers up to 60 A continuous current and supports overload ratings of 120 % or 150 % for 60 seconds. Optional keypad, communication modules (RS-232/485, CANopen, PROFIBUS) and expansion cards allow integration into larger automation systems while maintaining compact IP20 construction for panel mounting.
Frequently Asked Questions
Q: Does this inverter support hot-swapping?
A: No. Power must be isolated and the DC bus discharged before removal or installation. Live work on the power section risks arc flash and component damage.
Q: Is the VCB400-060 obsolete? Are there direct replacements?
A: The VCB series remains in use on many installed bases. Exact replacements keep the same power rating and control options. Confirm the full suffix (overload class, braking unit, keypad, communication) against the existing unit; firmware and parameter sets must match for seamless change-out.
Q: Will I lose my program during replacement?
A: Parameters are stored in non-volatile memory. Upload the complete parameter set with VPlus software or the KP100 keypad before removal. After installation, download the saved file and verify motor data and protection settings.
