Bonfiglioli ACT 400-018 FA Frequency Inverter
The Bonfiglioli ACT 400-018 FA Frequency Inverter is a Vectron drive unit intended for compatible industrial motor control applications. It is identified by the model ACT 400-018 FA, also written as ACT400-018FA. The inverter regulates the electrical supply to an electric motor so that speed and torque can follow the requirements of the machine process.
The ACT400 series is part of the Vectron drive range, which is used in machinery where a robust drive with configurable control functions is required. The drive should be integrated as part of a complete system that includes the motor, the power cables, the protection devices, the control interface, and the cabinet environment.
Drive Role and Control
The ACT 400-018 FA converts a fixed supply into a controllable output for the motor. It receives commands from the machine control system and responds according to the configured logic. Start and stop behaviour, speed references, and fault responses should be planned before commissioning.
The drive is not a substitute for isolation or for protective devices. Safety functions should follow the machine risk assessment.
Selection and Rating Review
The drive must be applied within its specified ratings. Selection should consider supply voltage, motor rating, load profile, duty cycle, ambient conditions, and cabinet space. If the application includes frequent starting, high overload, or regenerative operation, the system design should be reviewed.
The motor nameplate data should be entered accurately during commissioning. The control method and parameter structure should be confirmed for the specific model and firmware.
Cabinet Mounting and Cooling
The inverter should be mounted in a cabinet that provides mechanical support and environmental protection. The mounting surface should be stable and suitable for grounding. Airflow should not be blocked. Clearance around the drive should allow heat dissipation and access to terminals.
Labels should identify the drive and its main connections. The layout should allow safe measurement during commissioning and maintenance.
Power and Control Wiring
Power wiring should be performed by qualified personnel following the site electrical code. Supply, motor, and protective earth connections must be correct and secure. Cable sizes should be selected for current, voltage drop, and installation method. Motor cables should be shielded where required by the EMC plan.
Control wiring should follow the connection diagram. Digital and analog signals should be routed away from power cables. Terminal screws should be tightened and checked before power is applied.
EMC and Grounding
Frequency inverters can generate electrical noise. Good EMC practice includes separation of power and signal cables, proper shield termination, and low impedance grounding. Cabinet panels should be bonded where required.
If interference occurs, the user should inspect cable routing and grounding first.
Commissioning
Commissioning should begin with a visual inspection and safety check. The motor should be tested at low speed and light load. The user should observe current, speed stability, and noise. Direction of rotation should be confirmed.
Commissioning records should include the drive model, motor data, parameter changes, and test results.
Diagnostics and Maintenance
Diagnostics should consider supply quality, motor condition, load, wiring, and parameters. Repeated fault resets without investigation can hide a developing problem. The event history can help identify the sequence of events.
Routine maintenance should include checking cooling, terminals, and cabinet ventilation. The drive should be isolated and allowed to discharge before work.
Application Value
The ACT 400-018 FA supports adjustable speed control in compatible industrial machinery. It can help match motor output to process demand and reduce mechanical stress during starting and stopping.
Summary
The Bonfiglioli ACT 400-018 FA Frequency Inverter is intended for compatible industrial motor control. Correct selection, cabinet installation, wiring, EMC practice, parameter configuration, and maintenance are essential.
