BONFIGLIOLI VECTRON INVERTER 11 kW ACT410-23 4A
The BONFIGLIOLI VECTRON INVERTER 11 kW, model ACT410-23 4A, is an AC drive designed for adjustable speed control of three phase asynchronous motors. The Vectron ACT series is used in industrial automation and machine drive applications where controlled acceleration, energy efficient speed regulation, and motor protection are required. The 11 kW rating places the drive in the medium power range suitable for conveyors, pumps, fans, mixers, and packaging machinery.
Product Overview
A frequency inverter converts a fixed supply into an adjustable output voltage and frequency for a motor. By changing the output frequency, the drive controls motor speed; by regulating the voltage, it maintains appropriate motor flux. The Vectron ACT series includes a keypad and display for local parameter setting and monitoring. The drive supports configurable digital and analog inputs and outputs for integration with control systems.
The ACT410-23 4A is intended for panel mounting and industrial wiring. The 11 kW rating provides enough power for medium duty applications. The drive includes terminals for motor connection, braking resistor connection where supported, and control signals. Protective functions monitor overcurrent, overvoltage, undervoltage, overload, and overtemperature conditions.
Construction and Design
The inverter housing contains power electronics, control circuitry, cooling provisions, and terminal blocks. Heat is generated during operation, so the installation location must provide adequate ventilation and clearances. The drive should be mounted vertically on a rigid surface according to the recommended spacing. Power wiring should be separated from control wiring to reduce electrical noise.
The control terminals accept digital inputs for start and stop, direction, and preset speeds. Analog inputs can be used for speed reference from a potentiometer or external controller. Relay outputs can indicate drive status or fault conditions. The built-in keypad allows local control and parameter access.
Performance Characteristics
The Vectron ACT series supports V/f control and sensorless vector control. V/f control is suitable for simple fan and pump duties where dynamic response is not critical. Sensorless vector control improves torque performance at low speed and supports more demanding loads. The drive provides adjustable acceleration and deceleration ramps to control starting current and mechanical stress.
The output frequency range and carrier frequency are configurable. Higher carrier frequency can reduce motor noise but may increase drive losses. The drive monitors DC bus voltage and output current to protect the power stage. Braking resistor terminals allow energy from decelerating loads to be dissipated when required.
Applications
The Bonfiglioli ACT410-23 4A inverter is suitable for variable speed control of conveyors, pumps, fans, mixers, packaging machines, and general industrial drives. The 11 kW rating supports medium power applications. In conveyor systems, the drive supports soft starting and adjustable line speed. In pump and fan applications, speed control can reduce energy consumption.
The inverter can be integrated into control panels with PLCs, sensors, and other automation devices. Communication and I/O options allow the drive to receive speed references and report status to the control system. Correct selection of the drive rating, motor cable length, and protective devices helps ensure reliable operation.
Installation Guidelines
Installation should begin with a check of the nameplate data and a review of the product documentation. The drive should be mounted in a clean, dry location with adequate ventilation. Power wiring should be connected through appropriate protective devices. The motor cable should be sized for the current and length requirements. Control wiring should be separated from power wiring and shielded where necessary.
After wiring, the drive parameters should be set for the motor and application. Motor overload protection should be configured correctly. The direction of rotation should be verified before connecting the load. A low speed test run helps confirm that the drive and motor operate correctly.
Maintenance Recommendations
Regular maintenance supports reliable inverter operation. The cooling fans and heatsink should be kept clean to maintain airflow. Enclosure filters should be checked and replaced if necessary. Terminal connections should be inspected for tightness and signs of overheating. Parameter settings should be recorded for backup and troubleshooting.
In dusty or humid environments, additional protection may be required. The drive should be kept dry and free from conductive contamination. Maintenance records help identify trends and support planned servicing.
Selection Considerations
When selecting the ACT410-23 4A inverter, engineers should confirm the supply voltage, motor power, motor current, duty cycle, and control requirements. The 11 kW rating must be suitable for the motor and load. The installation environment affects cooling and enclosure requirements.
The control method should match the application. Simple fan and pump duties may use V/f control, while higher torque demands may benefit from sensorless vector control. Braking requirements should be evaluated for loads with high inertia or frequent stops.
Conclusion
The BONFIGLIOLI VECTRON 11 kW ACT410-23 4A inverter offers a medium power AC drive solution for three phase asynchronous motors. Its control features, configurable I/O, and protective functions support adjustable speed control in conveyors, pumps, fans, and packaging machinery. With correct installation and maintenance, the inverter provides reliable performance and long service life.
