Bonfiglioli ACT 401-22A Frequency Inverter
The Bonfiglioli ACT 401-22A Frequency Inverter is a Vectron drive unit intended for compatible industrial motor control applications. It is identified by the model ACT 401-22A, the software reference SW 4.1.1, and the code DSACT509003001. The inverter regulates the electrical supply to a motor so that speed and torque can follow the machine process requirements.
The software reference and code should be recorded because they help define the drive behavior and compatibility. The ACT 401-22A should be integrated as part of a complete drive system that includes the motor, cables, protection devices, control interface, and cabinet environment.
Drive Role and Software Reference
The ACT 401-22A provides adjustable output for compatible motor control. The software reference SW 4.1.1 identifies the firmware family associated with the unit. Firmware can affect parameter structure, supported functions, and diagnostic messages. The user should confirm that the software version is suitable for the application.
The drive receives commands from the machine control system and responds according to the configured logic. Start and stop behavior, speed references, and fault responses should be planned for the application. Safety functions must follow the machine risk assessment.
Model Identification and Compatibility
The model ACT 401-22A, the code DSACT509003001, and the software reference SW 4.1.1 should be checked against the project documentation. The complete identification helps confirm that the drive matches the intended application. Similar drive models can differ in rating, firmware, and configuration.
Compatibility includes the motor rating, supply voltage, control interface, and parameter support. If the drive is part of an existing system, the current configuration and firmware should be reviewed. A drive that fits mechanically may still require specific settings.
Cabinet Installation
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, software reference, and main connections. The layout should allow safe measurement and maintenance. If the cabinet includes other heat producing devices, the thermal design should be reviewed.
Power Wiring and Protection
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 and voltage drop. Motor cables should be shielded where required by the EMC plan.
Protective devices should be coordinated with the drive and motor. The user should confirm that short circuit and overload protection are suitable. Terminal screws should be tightened and checked before power is applied.
Control Wiring and Parameters
Control wiring should follow the connection diagram. Digital and analog signals should be routed away from power cables. Parameter setup should include motor data, frequency limits, acceleration and deceleration times, and input and output functions.
Parameters should be changed in a controlled manner and recorded together with the software reference. Default settings may not fit the application. The drive should be tested at low speed and light load before normal operation.
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. Sensors and communication lines are sensitive. A physical installation correction is often more effective than a parameter change.
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. Protective functions should be tested before normal operation.
Commissioning records should include the drive model, code, software reference, motor data, parameter changes, and test results. These records help future maintenance and replacement planning.
Diagnostics and Troubleshooting
Diagnostics should consider supply quality, motor condition, load, wiring, parameters, and software version. Repeated fault resets without investigation can hide a developing problem. The event history can help identify the sequence of events.
If the drive does not start, the user should check control commands, supply, and safety chain. If the motor runs roughly, the user should review motor data, load conditions, and mechanical alignment.
Maintenance and Service
Routine maintenance should include checking cooling fans, filters, terminals, and cabinet ventilation. Dust accumulation should be removed according to site policy. The drive should be isolated and allowed to discharge before work.
If the drive must be replaced, the replacement unit should be configured with the correct software and parameters, then tested with the motor. Parameter backups and commissioning notes reduce replacement time.
Application Value
The ACT 401-22A supports adjustable speed control in compatible industrial machinery. Recording the software reference and code helps maintain consistency across the installed base and supports efficient service.
Summary
The Bonfiglioli ACT 401-22A Frequency Inverter is intended for compatible industrial motor control. Correct selection, cabinet installation, wiring, EMC practice, parameter configuration, software verification, and maintenance are essential.
