Schneider ATV320U22N4C Altivar Machine ATV320 Variable Speed Drive — Specifications, Pricing, and Selection Guide

When a controls engineer or maintenance manager searches for the Schneider ATV320U22N4C by exact catalog number, the decision is already close. The question is not "what is a VFD" — it is "does this specific 2.2kW drive match my motor, my power supply, and my cabinet space, and can I get it quickly?" The ATV320U22N4C is part of Schneider Electric's Altivar Machine ATV320 series: a compact variable frequency drive rated at 2.2kW, accepting three-phase AC input at 380–500V, with a maximum output current of 5.5A, and an IP20 standard protection class suitable for dry industrial control cabinets. This article confirms the specifications, surfaces the ordering risks, and gives you an honest verdict on whether this is the right part for your application.

Who Should Buy the ATV320U22N4C — and Who Shouldn't

The ATV320U22N4C is the right choice when all of the following are true for your application:

  • Your incoming power supply is three-phase AC at 380–500V — single-phase power cannot be used with this drive under any configuration
  • Your motor nameplate power rating is 2.2kW or lower — the drive's rated capacity is a hard ceiling, not a guideline
  • Your motor is a three-phase asynchronous (induction) or synchronous AC motor — DC motors, stepper motors, and single-phase motors are not compatible
  • Your installation environment is a dry, enclosed control cabinet where IP20 protection class is adequate — wet, washdown, or dusty environments require a different protection class
  • Your cabinet has sufficient ventilation for passive convection cooling — this drive uses no internal fan and relies on airflow around it
  • Schneider Electric brand support and authorized North American distributor availability are relevant to your procurement or maintenance strategy

If your motor exceeds 2.2kW, look at the ATV320U32N4C (3.2kW) or ATV320U42N4C (4.2kW) in the same series. If your power supply is single-phase or outside the 380–500V band, a different drive family is required. If your environment demands IP54 or higher, the broader Altivar product line has suitable options.

What the ATV320U22N4C Actually Does in Your System

The ATV320U22N4C converts fixed-frequency three-phase AC power — your facility's 380–500V supply at 50Hz or 60Hz — into a variable-frequency, variable-voltage output that controls motor speed and torque precisely. This is the core function of any variable frequency drive, and the Altivar Machine ATV320 series executes it in a compact, DIN-rail or panel-mountable form factor that allows vertical stacking of multiple drives in the same cabinet. The 5.5A maximum output current defines the usable motor load ceiling and is the number your cable sizing, disconnect switch, and overcurrent protection calculations must reference.

The drive supports both asynchronous (induction) motors — the dominant type in industrial machinery worldwide — and synchronous motors, which is verified directly on Schneider Electric's product page. Input frequency is auto-detected at 50Hz or 60Hz, which means the same physical unit can be deployed in North American 60Hz facilities or 50Hz environments without firmware changes. This dual-frequency capability is factory-confirmed, not inferred.

The IP20 protection class is the standard offering. IP20 is appropriate for installation inside a clean, dry control enclosure. An IP21 variant exists for environments with occasional moisture exposure. Neither rating is appropriate for outdoor, high-humidity, explosive, or chemically corrosive environments — if those conditions apply, the Altivar Machine ATV320 in this protection class is not the correct product.

Typical System Architecture and Signal Chain

The ATV320U22N4C sits between the facility's three-phase power distribution and the motor it controls. Understanding its position in the chain prevents both wiring errors and specification mismatches.

  • Facility three-phase AC distribution panel (380–500V, L1/L2/L3) feeds a three-pole circuit breaker or motor disconnect switch upstream of the drive
  • The circuit breaker output connects to the drive's power input terminals (L1, L2, L3 or R, S, T per regional convention)
  • The drive's output terminals (U, V, W) connect to the three-phase AC motor via shielded cable — shielding reduces electromagnetic interference to nearby signal wiring
  • A separate control signal path — typically a terminal block accepting 24VDC start/stop logic and a 0–10V or 4–20mA analog speed reference — connects the drive to the PLC or control system
  • The drive chassis ground connects to the facility ground bus, and the motor frame is independently grounded per local electrical code

Where This Drive Gets Deployed: Industries and Use Cases

The 2.2kW power class covers a wide range of light industrial and commercial machinery. Packaging and labeling lines are among the most common deployments — transport belt motors, label applicator drives, and positioning actuators all fall within this power range and benefit directly from variable speed control. The compact form factor of the ATV320 series is particularly valued in OEM machine builders who are fitting multiple drives into a single cabinet.

Material handling applications — specifically conveyor systems, vertical lift motors, and product sorting mechanisms — regularly specify drives in this power class. Speed regulation on conveyors allows synchronization with upstream and downstream equipment without mechanical gearbox changes. In food processing and beverage production, the ability to modulate conveyor belt speed and proportional valve drive mechanisms directly improves line efficiency and reduces product damage.

Pump speed modulation for water circulation, process fluid loops, and light HVAC applications also represents a common deployment. At 2.2kW, the drive fits centrifugal pump motors in the 2–3 horsepower range. Machine tool spindle drives for light-duty lathes and milling centers round out the application picture, where precise speed control across a wide RPM range is essential.

Application Typical Deployment
Packaging and labeling machinery Variable speed control of transport belts and label applicator motors
Conveyor and material handling systems Speed synchronization across conveyor zones; lift motor regulation
Food and beverage processing lines Proportional belt speed control; wash-cycle compatible via cabinet integration
Pump speed modulation Water circulation or process fluid flow control; replaces throttling valves
Light-duty machine tool spindles Variable RPM for lathe and milling spindle speed control
HVAC fan and air handling units Fan speed modulation for energy-efficient air volume control

ATV320U22N4C vs. Other Altivar Machine Series Variants — Which Power Rating Do You Need?

The Altivar Machine ATV320 series uses a consistent compact form factor across its power range. If your motor nameplate is not 2.2kW, the correct selection shifts to the adjacent model in the series. Using an oversized drive for an undersized motor wastes capital without adding protection; using an undersized drive risks thermal fault and shutdown under load.

Model Power Rating Primary Use Case Notes
ATV320U11N4C 1.1 kW Small machinery, light-duty positioning drives Step down for lower power requirements
ATV320U22N4C 2.2 kW Packaging, conveyor, light industrial machinery This model — standard light industrial offering
ATV320U32N4C 3.2 kW Medium industrial machinery, heavier conveyors Step up when load consistently approaches or exceeds 2.2kW
ATV320U42N4C 4.2 kW Larger machinery, demanding duty cycles Higher power variant for more demanding applications

If your motor nameplate reads above 2.2kW, the ATV320U32N4C is the correct next step — confirm the right variant and check availability at LeadTime.ca before placing your order.

Expert Verdict: Is the ATV320U22N4C the Right Drive for This Job?

The ATV320U22N4C earns its place in a specification list by doing exactly what the 2.2kW light industrial segment needs: straightforward variable speed control of standard three-phase motors in a compact, stackable form factor with a support network that most plant engineers can access without difficulty. The 5.5A output current ceiling, the verified compatibility with both asynchronous and synchronous motors, the 50Hz/60Hz auto-detection, and the 12-month warranty make this a low-risk procurement for facilities already on three-phase 380–500V infrastructure. It is the right choice for plant engineers managing packaging lines, conveyor systems, or pump applications where motor power falls at or below 2.2kW and the installation environment is a clean, ventilated control cabinet. System integrators specifying OEM machinery at this power class will find the compact form factor and vertical stacking capability genuinely useful when fitting multiple drives into a single enclosure.

Where this drive has real limits: it is not the answer for single-phase power environments, applications above 2.2kW, or anything requiring IP54 or better protection against moisture, dust, or chemical exposure. For the next power step, the ATV320U32N4C covers 3.2kW in the same series without changing the ecosystem. For wet or harsh environments, the broader Altivar product line — not this specific series — is the correct direction. And for organizations where cost is the primary constraint and brand support is secondary, lower-cost generic VFDs from other manufacturers exist in this power class, though they trade away Schneider's documentation depth and distributor support network. The one non-negotiable before purchasing: physically measure the voltage at your disconnect switch with a multimeter and confirm three-phase 380–500V is present. More ATV320U22N4C projects are delayed by incorrect power supply assumptions than by any other single factor.

From a procurement standpoint, the ATV320U22N4C is a standard catalog item with established distributor channels worldwide, but real-world lead times from authorized North American distributors run approximately 15–25 business days depending on regional stock levels. Backorder risk increases during peak manufacturing seasons, and lead times from the original manufacturing location in Indonesia are considerably longer. Ordering through a specialist distributor like LeadTime.ca gives you access to pre-order compatibility consultation — confirming voltage, motor type, and protection class before the order ships, not after it arrives — along with clear warranty terms and direct support for North American buyers.

What Engineers Need to Know Before Ordering the ATV320U22N4C

Community discussion specific to the ATV320U22N4C catalog number is sparse in publicly accessible forums — this is typical of a standard industrial component that works as documented and generates support tickets only when installation mistakes occur. The more useful body of knowledge for this drive comes from the recurring patterns of ordering errors and commissioning failures that specialist distributors and applications engineers see across the Altivar Machine series. These are not hypothetical; they are the reason LeadTime.ca's pre-order consultation step exists.

The most consequential mistake is power supply misidentification. Engineers sourcing a replacement drive or specifying a new installation occasionally assume three-phase availability based on facility drawings or verbal confirmation from maintenance staff, then discover at commissioning that the circuit routed to the cabinet is single-phase. The ATV320U22N4C will not operate on single-phase power — and the potential for input circuit damage means this is not simply a nuisance fault. Measuring actual phase-to-phase voltage at the disconnect before the drive is connected is not optional. Similarly, the protection class question — IP20 versus IP21 — is frequently bypassed during specification, leading to incorrect installations in environments with incidental moisture. IP20 is the standard offering for this catalog number; if there is any possibility of washdown or high-humidity exposure, confirm whether IP21 is appropriate or whether the application calls for a different product series entirely.

Thermal management is the third consistent failure point. The ATV320U22N4C uses passive cooling with no internal fan, which means its thermal performance is entirely dependent on the airflow environment of the installation cabinet. Sealed enclosures without ventilation or fan-assisted cooling will trigger thermal alarms and, over time, shorten the drive's service life. The integrated thermistor provides a warning before shutdown, but the correct response is designing adequate ventilation into the cabinet before installation — not responding to thermal alarms after they appear. When ordering multiple drives for vertical stacking, calculate the combined thermal load and confirm the cabinet cooling strategy handles the aggregate dissipation at your maximum ambient temperature.

Wiring and Installation Overview

This section provides a high-level overview of installation requirements. Full wiring diagrams and connection procedures are documented in the Schneider Electric commissioning manual for the ATV320 series — always consult the manufacturer's documentation for detailed procedures.

  • Connect three-phase AC input (L1, L2, L3 or R, S, T per local convention) from a three-pole circuit breaker or motor disconnect switch rated for the drive's input current; the 5.5A maximum output current is the reference for sizing upstream overcurrent protection
  • Connect motor output leads to drive terminals U, V, W; use shielded cable where electromagnetic compatibility is a concern, and confirm cable gauge is appropriate for the run length and load current
  • Connect the drive chassis ground to the facility ground bus and ensure the motor frame is independently grounded per applicable electrical code — CE marking confirms electromagnetic compatibility with correct installation, but shielded cables may be required to meet EMC category requirements
  • Control signal wiring (start/stop, speed reference) connects to the drive's terminal block; typical configurations accept 24VDC dry-contact logic for start/stop and either 0–10V or 4–20mA analog input for speed reference — confirm signal types against your PLC output specifications before wiring
  • Verify input voltage at the disconnect with a multimeter before energizing the drive; confirm all three phase-to-phase voltages are within 380–500V and that phase sequence is correct — incorrect phase sequence will cause the motor to run in reverse, corrected by swapping any two motor output leads

Commissioning Overview

Full parameter configuration procedures are contained in the Schneider Electric commissioning documentation. The following summarizes the key steps engineers should plan for:

  • Before power-up, confirm motor nameplate data is available (rated power, voltage, frequency, full-load amperage, and motor type — asynchronous or synchronous) and that the installation environment's ambient temperature is within operating range
  • Access drive configuration via commissioning software (Schneider SoMove or equivalent) or the drive's onboard interface; enter motor nameplate parameters including the 2.2kW power rating, rated speed, and frequency
  • Set acceleration and deceleration ramp times appropriate for the load inertia; typical starting points are 3–10 seconds, adjusted based on how the mechanical load responds during no-load testing
  • Configure control input signal types and speed reference range — verify the analog input signal voltage is present and correctly scaled at the terminal block before enabling the start command
  • Run a no-load test at low speed before connecting to full mechanical load; confirm correct motor rotation direction and smooth ramp behavior before advancing to full-speed operation

Wrong-Part Prevention Checklist

Before placing your order for the ATV320U22N4C, work through this checklist. Each item represents a documented source of incorrect orders and post-delivery returns:

  1. Confirm input power is 3-phase AC at 380-500V—single-phase motors and power cannot use this drive
  2. Verify motor nameplate power is 2.2kW or lower; oversizing the drive for undersized motors wastes capital
  3. Check motor type compatibility: this drive works with both asynchronous (induction) and synchronous motors
  4. Confirm IP20 or IP21 protection class matches the installation location (covered control cabinet vs. washdown area)
  5. Calculate heat dissipation: drives generate waste heat; confirm installation space allows adequate ventilation
  6. Verify mechanical mounting: ensure DIN rail or panel mounting space and cable entry points are available
  7. Check firmware version and commissioning software availability in your region (North American support may vary)

If any item on this checklist raises a question, contact the LeadTime.ca team before ordering — confirming fit before the order ships is faster and less costly than processing a return after delivery.

Frequently Asked Questions

Can the ATV320U22N4C run on a single-phase 240V supply if I use a phase converter upstream?

The drive requires three-phase AC at 380–500V at its input terminals. While a rotary phase converter can theoretically generate three-phase power from a single-phase supply, this configuration is not officially supported and may affect the drive's input current characteristics and warranty status. If your facility has only single-phase power, a different drive family designed for single-phase input is the correct specification path.

What happens if motor load briefly exceeds 2.2kW — does the drive shut down immediately or does it derate?

The drive supports a typical overload capacity of 150% of rated current for 1 minute, which provides a buffer for motor inrush on startup and brief load spikes. Beyond the overload window, the integrated thermistor and drive protection logic will issue a warning and, if the condition persists, shut the drive down to protect both the drive and motor. The commissioning manual specifies exact overload timing and reset procedures for this model.

Is the ATV320U22N4C a direct replacement for older Altivar series drives in an existing installation?

The ATV320 series is not a pin-for-pin or terminal-for-terminal replacement for all previous Altivar models. Terminal layouts, parameter structures, and commissioning software may differ between generations. Before ordering as a replacement, compare the terminal block layout of the drive being replaced against the ATV320U22N4C installation guide, and confirm that control signal wiring is compatible without re-termination.

Does this drive support Modbus RTU or Ethernet fieldbus communication with a PLC?

Fieldbus and network communication capability in the ATV320 series depends on the specific variant and any optional communication modules. The base ATV320U22N4C catalog number should be verified against the Schneider Electric product page for built-in communication options. If Modbus RTU, CANopen, or Ethernet integration is required for your PLC architecture, confirm the communication interface before ordering rather than assuming it is included.

What do the drive's LED indicators mean during normal operation versus a fault condition?

LED indicator states — power, run, and fault — are documented in the ATV320 commissioning manual with specific fault codes and recommended corrective actions. Common fault conditions include input voltage out of range (confirm 380–500V three-phase is present), thermal overload (confirm cabinet ventilation is adequate), and motor overcurrent (confirm motor load does not exceed 2.2kW). The manufacturer's fault code reference is the authoritative source; do not attempt to interpret LED patterns without the manual present.

What is the realistic lead time for the ATV320U22N4C in North America, and is it likely to be in stock?

Authorized North American distributors typically quote 15–25 business days for the ATV320U22N4C, with actual availability varying by region and season. The drive is manufactured in Indonesia, which means direct-from-manufacturer lead times are considerably longer. In-stock availability at regional distribution centers improves turnaround, but stock status should always be confirmed at time of order — backorder risk increases during peak manufacturing periods. Contact LeadTime.ca directly for a current lead-time confirmation before committing to a project schedule.
