Danfoss 131G0447 FC 302 4 kW Frequency Inverter
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Danfoss 131G0447 is a VLT AutomationDrive FC 302 frequency inverter, also known as a variable frequency drive, for industrial motor control. Model/type FC-302P4K0T5E20H2BGCXXXSXXXXA0BXCXXXXD0 is rated at 4 kW or 5 HP and uses a three-phase 380-500 V AC supply. It supports induction, permanent-magnet and synchronous reluctance motors for applications requiring controlled motor speed, torque and process operation. The IP20 chassis enclosure is intended for installation inside a suitable control cabinet or protected electrical enclosure.
This configuration includes an integrated dynamic brake chopper for controlled stopping and regenerative braking applications, together with an H2 Class A2/C3 RFI filter. The Graphical Local Control Panel supports local setup, monitoring, diagnostics and parameter backup or restoration. For engineering access, the USB Mini-B service interface connects the drive with VLT Motion Control Tool MCT 10. A replacement should match the complete part number, typecode configuration, voltage family, power rating, enclosure and option configuration; parameter transfer or restoration may be required before the spare can operate in the machine.
The FC 302 provides an RS-485 terminal-strip interface supporting Modbus RTU and Danfoss FC Protocol, while the Graphical LCP, MCT 10 and RS-485 status word readout provide diagnostic access. The ON LED indicates an active power supply, WARN indicates a warning while the drive continues to operate, and a flashing ALARM LED indicates a trip or fault condition that stops motor output. During replacement or troubleshooting, check the installed configuration, communication connection and brake resistor wiring before returning the drive to service. Conformally coated PCBs provide added protection for the drive electronics in demanding industrial environments.

Programming and Configuration
The Danfoss Graphical LCP provides local parameterization, monitoring, diagnostics and parameter backup or restoration. Four independent parameter setups can be stored in internal non-volatile EEPROM memory, supporting configuration management for the FC 302 drive.
The USB Mini-B engineering interface enables connection to VLT Motion Control Tool MCT 10 for commissioning, troubleshooting, parameter management and configuration transfer. When installing a spare, transfer or restore the machine parameters and confirm that the drive configuration matches the original unit before operation.
The complete typecode must be checked against the failed drive, including the 380-500 V AC supply range, 4 kW / 5 HP rating, IP20 chassis enclosure, RFI filter, brake chopper and option configuration. Brake resistor wiring should also be checked as part of commissioning.
Communication and System Integration
The FC 302 provides a built-in RS-485 terminal-strip interface for serial integration. Supported protocols are Modbus RTU and Danfoss FC Protocol, allowing the drive to operate within compatible RS-485 networks.
The USB Mini-B service interface is intended for connection to VLT Motion Control Tool MCT 10 during commissioning, troubleshooting, parameter management and configuration transfer. The Graphical LCP provides local access to drive setup and monitoring.
RS-485 status word readout provides a further diagnostic method. For replacement work, retain the required communication configuration and verify the network connection before placing the drive back into automatic operation.
Diagnostics and Status Indication
Drive status and faults can be viewed through the Graphical LCP readout and Alarm Log menu. VLT Motion Control Tool MCT 10 provides additional commissioning and troubleshooting access, while the RS-485 interface supports status word readout.
The front-panel indicators distinguish normal power, warning and trip conditions. ON shows that the power supply is active, WARN indicates a warning while operation continues, and a flashing ALARM indicates a trip or fault condition in which the drive stops motor output.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| ON | Green - On | Power supply is active |
| WARN | Yellow - On | A drive warning condition is present; the unit continues operation |
| ALARM | Red - Flashing | A trip or fault condition is present and the drive stops motor output |
Replacement and Spare Part Considerations
For a Danfoss 131G0447 replacement, compare the complete part number and model/type FC-302P4K0T5E20H2BGCXXXSXXXXA0BXCXXXXD0. The replacement must match the 4 kW / 5 HP rating, three-phase 380-500 V AC supply, IP20 chassis enclosure, H2 Class A2/C3 RFI filter, integrated dynamic brake chopper and option configuration.
A spare drive may require parameter transfer or restoration before commissioning. Configuration backup and restore are supported through the Graphical LCP or VLT Motion Control Tool MCT 10, and four independent parameter setups are stored in internal non-volatile EEPROM memory.
Before returning the machine to operation, verify the RS-485 communication connection, required Modbus RTU or Danfoss FC Protocol settings and brake resistor wiring. When a fault remains after configuration and connection checks, a repair or tested exchange unit can provide a practical route to restoring the drive.
