Programming a Fuji Electric FRENIC AC drive can be done in several ways depending on the model and user preference. Below are the most common methods used to configure and tune a FRENIC drive:
Built-in Keypad (Digital Operator)
Most FRENIC drives come with a built-in or detachable keypad for manual programming.
Features:
- 7-segment display or LCD screen (varies by model)
- Scroll through parameters using arrow keys
- Easily set motor data, acceleration/deceleration time, frequency limits, I/O logic, etc.
Ideal For:
- Quick setup or on-site adjustments
- Users without a PC or software
PC-Based Programming via FRENIC Loader Software
Fuji Electric offers FRENIC Loader, a free Windows-based software tool.
Features:
- View, edit, and save parameter sets
- Upload/download settings from drive
- Monitor real-time performance (speed, current, voltage)
- Save backups and clone settings to multiple drives
Requirements:
- PC with Windows OS
- USB-to-RS485 converter or USB cable (depends on drive model)
Ideal For:
- Commissioning multiple drives
- Advanced tuning and diagnostics
- Creating parameter backups
Smart Loader USB (For Some Models)
Select FRENIC models support a Smart Loader USB interface, allowing parameter transfer via USB memory stick.
Features:
- Plug-and-play configuration transfer
- Great for OEMs and field engineers
- No PC needed on site
Ideal For:
- Rapid drive setup in the field
- Preconfigured installations
Remote Keypad / Digital Operator (Optional Accessory)
External operator panels (e.g., TP-E1-E) allow you to program the drive remotely from outside an enclosure.
Features:
- Full keypad with display
- Extended reach via cable
- IP54 or better enclosures available
Ideal For:
- Control panels
- Hazardous or hard-to-access drive installations
Fieldbus or Network Communication
Many FRENIC drives support network programming through fieldbus options like:
- Modbus RTU
- Ethernet/IP
- Profibus
- BACnet/IP (HVAC models)
Features:
- Set parameters and issue run/stop/frequency commands via PLC or SCADA
- Monitor drive status remotely
Ideal For:
- Automated or integrated control systems
- Facility-wide drive management\
Preset Programs & Macros (Model-Dependent)
Some FRENIC series (like the FRENIC-HVAC or FRENIC-MEGA) offer preloaded function sets or application-specific macros (e.g., pump, fan, conveyor).
Features:
- Quick setup using wizards
- Logical groupings of parameters
- Simplifies common applications
Pro Tips for Programming FRENIC Drives:
- Always start by entering motor nameplate data (parameter group F)
- Use auto-tuning (if supported) for optimized motor performance
- Save a parameter backup before making major changes
- Use monitoring mode to view real-time performance during testing
- Refer to the drive’s parameter manual for detailed descriptions and function codes
