Danfoss 134F6769 at a glance
The Danfoss 134F6769 is a 3.0 kW / 4.0 HP VLT HVAC Drive FC 102 for 3 × 380–480 V AC supplies, made for the fans, pumps and compressors in building services. It is a frame A4, IP66 / UL Type 4X, A4 frame unit, built for wall mounting in wet, dusty or wash-down locations.
This configuration has RFI class A1/B (C1), no brake chopper, and a graphical LCP 102 control panel. The full type code is decoded alongside the FAQs.
Sizing and installation
- Continuous output current: 7.2 A / 6.3 A. Size the drive on the motor nameplate current at your actual supply voltage.
- Intermittent (overload) current: 7.92 A / 6.93 A — the normal-overload rating that suits variable-torque fan and pump loads.
- Enclosure: IP66 / UL Type 4X, A4 frame — built for wall mounting in wet, dusty or wash-down locations.
- EMC: RFI class A1/B (C1). Check the permitted screened motor cable length in the Danfoss FC 102 Design Guide.
FC 102 features for HVAC
- Built-in RS-485 protocols: Danfoss FC, Modbus RTU, BACnet MS/TP, Metasys N2 and FLN Apogee — connects to most building management systems without an option card.
- Fire Mode keeps the drive running during an emergency, for example to keep smoke-extract fans turning.
- Automatic Energy Optimisation (AEO) cuts motor losses at part load — Danfoss quotes a further 5–15% saving.
- Pump and fan functions: sleep mode, dry-pump, end-of-curve and broken-belt detection, plus a built-in cascade controller for pump sets.
- Built-in DC coils limit mains harmonics (EN 61000-3-12).
- Smart Logic Controller for simple sequencing without a PLC.
Where the energy saving comes from
Centrifugal fans and pumps follow the affinity laws: absorbed power falls with the cube of speed. Running at 80% speed needs roughly half the power of full speed (0.8³ ≈ 0.51, before motor and drive losses) — which is why speed control pays back faster on fans and pumps than almost any other load.

Frequently asked questions
Which communication protocols are built in?
Danfoss FC, Modbus RTU, BACnet MS/TP, Metasys N2 and FLN Apogee over the built-in RS-485 port. This unit has no fieldbus option card fitted, so PROFIBUS, PROFINET, EtherNet/IP or BACnet/IP would need an MCA option card.
What output current does it deliver at 400 V and at 480 V?
Continuous output current is 7.2 A / 6.3 A; intermittent current is 7.92 A / 6.93 A. Always size on the motor nameplate current at your supply voltage.
Can this drive be wall mounted without a panel?
Yes. The IP66 / UL Type 4X, A4 frame enclosure is designed for direct mounting.
