Danfoss 195N1041 VLT2815PT4B20STR0DBF10A00 — VLT 2800 Series 1.5 kW Compact AC Drive

Danfoss · VLT 2800 · VFD / Inverter · 1.5 kW · 3-Phase 380–480 V

The Danfoss 195N1041 (VLT2815PT4B20STR0DBF10A00) is a 1.5 kW compact AC drive from the Danfoss VLT 2800 family, designed for 3-phase 380–480 V industrial mains. It integrates a built-in RFI filter, an integrated brake chopper, RS-485 Modbus RTU communication and a removable LCP local control panel, making it a workhorse for brownfield retrofits, MRO replacement and OEM machine builds where compactness, reliability and easy commissioning matter more than fieldbus breadth. KOEED sources the full VLT 2800 family alongside Allen-Bradley PowerFlex, Siemens Sinamics, Mitsubishi FREQROL, Omron MX2 / RX, Fanuc spindle drives, Schneider Altivar, Yaskawa V1000 / A1000, Panasonic Minas and KEYENCE servo platforms, so multi-brand bills of materials can be quoted in one email.

1. Key Technical Specifications & Overview

The full ordering code VLT2815PT4B20STR0DBF10A00 decodes the VLT 2800 series naming convention. VLT2815 places the unit in the 1.5 kW power class; the trailing “PT” denotes the PC Tool programming option (VLT Motion Control Tool MCT-10). The “4” declares a 3-phase 380–480 V AC input, B20 adds a brake chopper and built-in RFI filter, ST indicates the standard control variant, R0 means no integrated display (LCP is supplied separately or shared across drives), and DBF10A00 packages the options suffix used by Danfoss configurators. The drive is housed in a compact IP20 / NEMA 1 frame size A2 chassis suitable for cabinet mounting, with side-by-side and book-style installation supported to save panel space on dense machine layouts.

2. Application Scenarios & Where It Fits

The VLT 2815 1.5 kW is the classic “general purpose” drive for the 0.37–1.5 kW power band. It is the right pick when the load is a standard induction motor in the 1–2 HP range and the user does not need safety-rated STO or high-speed fieldbus. Typical deployments include:

• Pumps and fans — HVAC air handling units, chilled water pumps, exhaust fans; the integrated PID and skip-frequency bands suit constant-air-volume boxes.
• Conveyors and material handling — packaging lines, sortation, palletizers running a few hours per shift.
• Mixers, agitators and small extruder screws in food, chemical and plastics plants.
• Simple hoist and winch positioning where the integrated brake chopper dissipates regenerative energy.
• OEM machine builds — textile machines, washing systems, small woodworking CNCs feeding a Fanuc or Mitsubishi controller, or a Siemens SIMATIC S7 cell.
• Brownfield MRO — replacing 20-year-old Allen-Bradley 1336 or Yaskawa VS mini units on existing conveyors where a direct-fit compact form factor is preferred.

The VLT 2800 family has been in continuous production for roughly a decade, so it is well supported in the field, well documented, and widely understood by maintenance technicians — an important consideration for plants that standardise on Danfoss and need fast MRO turnaround rather than the latest iC2 / iC7 platform.

3. Integration & Wiring Notes

Power terminals follow the standard Danfoss VLT 2800 layout for the A2 frame: L1 / L2 / L3 for the incoming 3-phase 380–480 V mains, U / V / W for the motor output, and DC+ / BR for the external brake resistor. Control terminals include 6 digital inputs, 2 analog inputs (0–10 V or 0/4–20 mA, switchable), 1 analog output, 2 relay outputs, and the RS-485 Modbus RTU pair (terminals 68 / 69). The factory default for the analog input is voltage; for current-loop setpoints from a PLC, parameter group 3 must be reconfigured.

When tying the VLT 2815 into a multi-brand cell — for example a Siemens S7-1200, a Omron CP1H, a Schneider Modicon M340 or a Panasonic FP-X — Modbus RTU on terminals 68/69 is the simplest path. For higher-level Modbus frame generation and CRC validation, KOEED’s free calculator helps pre-build request frames. The drive also accepts a hardware STO-style safe-stop input via the digital terminals when wired per Danfoss application note MN.20.A1.01; for category 3/PL d machinery safety, an external safety relay is normally added.

The integrated RFI filter (B20 option) makes the drive compliant with EN 61800-3 Class A1, so cabinet installation does not require an external line filter in most industrial environments. For machine builders exporting into residential or light-commercial environments where EN 55011 Class B applies, the B20 filter still helps, but a short motor cable (under 5 m) and proper grounding of the motor housing are mandatory to keep emissions inside the limit. Earth the drive chassis to the cabinet PE bus with a short, large-gauge strap — not through the mounting bolts alone.

4. Installation & Commissioning Tips

Plan for at least 100 mm of clearance above and below the drive for vertical cooling airflow. The VLT 2800 frame A2 supports side-by-side mounting with no derating, which is useful when packing several drives into a single cabinet. The book-style (flat-mount) option requires the optional mounting bracket. Ambient temperature must stay between −10 °C and +40 °C without derating; up to +50 °C requires either a derate or forced cabinet ventilation.

On first power-up, run the Quick Menu for motor data (parameter 1-20/1-22 /1-23) and confirm ramp times in 3-4x (accel) and 3-8x (decel). For a 1.5 kW pump or fan, a 5–10 second accel/decel ramp is a safe starting point. If the load is a brake-controlled hoist, drop decel to 1–2 s and verify the brake resistor ohm value against the drive’s minimum permitted R_min (printed on the label) — never go below it.

Most field issues with the VLT 2815 trace to three root causes: (1) the analog input configured for voltage while the PLC outputs current, giving full-scale-at-zero behaviour, (2) the STO / safe-stop terminal left open, preventing the start command, and (3) the brake resistor undersized for the duty cycle, which trips warning “W19”. Use the LCP 2 to read the active alarm number, then cross-check the code in the PLC Error Code Database or feed the photo of the rating plate into the AI Diagnostic Tool for a faster cross-reference.

For firmware programming, MCT-10 (Danfoss PC Tool) connects via the drive’s RS-485 port using the traditional 9-pin to terminal adapter. Parameter sets can be backed up to the LCP 2 and cloned across a fleet, which is convenient for OEM builds with multiple identical lines. Always lock parameter group 0 (parameter 0-60 = [1] Locked) once commissioning is complete to prevent field operators from changing critical setpoints.

5. Procurement, Warranty & Lead Time

The 195N1041 is part of the VLT 2800 long-running catalog, with broad aftermarket availability through the channel. KOEED typically keeps both new-surplus and tested pull units on the shelf for fast MRO. Each drive is inspected for visible damage, power-on smoke-test (no-load), and parameter reset to factory defaults before shipment.
