Schneider ATV310HU15N4 Replacement for Altivar 310

Product Overview

Schneider ATV310HU15N4 Replacement for Altivar 310: Seamless Migration & Smooth Transition

The Schneider Electric ATV310HU15N4 is a 1.5 kW (2 HP) three-phase 380–460 V AC variable frequency drive from the Altivar 310 series, engineered for pump and fan applications in industrial environments. As legacy control systems age and original equipment reaches end-of-life, plant engineers and maintenance teams increasingly seek a reliable, drop-in replacement that preserves existing wiring infrastructure, retains communication compatibility, and minimises production downtime during the changeover. TOPNLMS stocks verified ATV310HU15N4 units and provides full migration support to help you execute a smooth, low-risk upgrade.

Whether your facility is retiring an older Altivar 28 or Altivar 31 drive, consolidating a mixed-brand VFD fleet, or simply replacing a failed unit on an urgent basis, the ATV310HU15N4 offers a well-documented upgrade path. Its compact DIN-rail-compatible footprint fits standard control cabinet cutouts, and its terminal block layout closely mirrors predecessor models, reducing rewiring effort to a minimum. The drive supports Modbus RTU communication natively over RS-485, making it immediately compatible with existing SCADA systems, Schneider Electric Modicon M340 PLCs, and third-party HMI panels without gateway hardware.

Seamless Upgrade Solutions

A successful ATV310HU15N4 retrofit rarely involves the drive alone. During the migration process, engineers typically audit and replace several adjacent components to ensure system-wide reliability. The VW3A1104 RJ45 Modbus communication cable is the standard accessory for connecting the ATV310 to a PC running SoMove configuration software, allowing parameter upload, comparison, and download without manual keypad entry — a critical time-saver when replacing multiple drives across a production line.

On the power supply side, the ABL8REM24030 Phaseo regulated 24 V DC power supply is commonly installed alongside the ATV310HU15N4 to feed the drive’s control circuit and any associated Preventa XPS safety relay modules in the same cabinet. Where the existing cabinet uses a Modicon TM3 expansion I/O rack connected to a Modicon M221 or M241 logic controller, the ATV310’s native Modbus RTU port integrates directly without additional protocol converters, preserving the existing network topology.

For applications where the legacy system used a Telemecanique LC1-D series contactor upstream of the old drive, that contactor can typically be retained as-is, since the ATV310HU15N4 input current profile is compatible with standard IEC contactor sizing for 1.5 kW loads. If the retrofit involves upgrading the motor protection scheme, pairing the drive with a TeSys GV2 manual motor starter on the input side provides both short-circuit and overload protection in a compact form factor suited to existing DIN rail space.

In multi-drive installations — such as HVAC air-handling units or water treatment pump stations — it is common to replace the ATV310HU15N4 alongside neighbouring ATV310HU22N4 (2.2 kW) or ATV310HU40N4 (4.0 kW) units during the same maintenance window, standardising the cabinet on a single drive family and simplifying spare-parts inventory. Signal isolation between the drive’s analog output and a legacy 4–20 mA PID loop can be maintained using a ZCAT signal conditioner or equivalent DIN-rail isolator if the existing field wiring impedance is outside the ATV310’s specified range.

Retrofit Guidance FAQ

Q: Can I reuse the existing motor cable and wiring?
A: In most cases, yes. The ATV310HU15N4 uses standard screw-terminal U/V/W output connections. Verify cable cross-section against the drive’s rated output current (4.1 A at 1.5 kW) and ensure the cable shield is bonded to the drive’s PE terminal at the drive end only to avoid ground loops.

Q: Do I need to re-enter all drive parameters manually?
A: Not necessarily. Schneider Electric’s SoMove software (free download) can read parameters from a connected ATV310 and store them as a project file. If the outgoing drive is still functional, export its configuration first, then import to the replacement unit via the VW3A1104 programming cable. If the old drive has failed, parameters must be re-entered from the original commissioning sheet or reconstructed from motor nameplate data.

Q: Is Modbus RTU addressing affected by the swap?
A: No. The Modbus slave address, baud rate, and parity are stored in the drive’s NVM and must be set to match the existing network configuration (typically address 1–247, 19200 bps, even parity for Altivar 310 default). These settings are accessible via the drive’s front keypad or SoMove without any hardware changes to the RS-485 wiring.

Q: Will the ATV310HU15N4 fit in the same cabinet cutout as the Altivar 31?
A: The ATV310 series has a slightly different depth profile compared to the ATV31. Verify the cabinet depth clearance (minimum 149 mm behind the mounting plate) and confirm that the existing cable entry glands align with the ATV310’s terminal cover position. In most standard 400 mm deep enclosures, no mechanical modification is required.

Q: What communication protocols does the ATV310HU15N4 support natively?
A: The drive includes a built-in Modbus RTU (RS-485) port as standard. CANopen, DeviceNet, PROFIBUS DP, and Ethernet/IP connectivity are available via optional communication cards (e.g., VW3A3607 for PROFIBUS DP), allowing integration into virtually any existing plant network architecture without replacing the host PLC or SCADA system.

Warranty Assurance

Every ATV310HU15N4 unit shipped by TOPNLMS is covered by a 12-month warranty from the date of delivery. Prior to dispatch, each drive undergoes a functional power-on test and visual inspection to confirm correct display operation, fan function (where applicable), and absence of physical damage. Units are packed in anti-static foam-lined cartons with desiccant to protect against humidity during international transit.

In the event of a confirmed defect within the warranty period, TOPNLMS will arrange a replacement unit or issue a full refund — whichever the customer prefers — with return freight covered on our account. Our technical support team is available via email at [email protected] to assist with installation queries, parameter configuration, and compatibility verification before and after purchase. Typical order processing time is 1–2 business days, with DHL Express and FedEx International Priority options available for urgent replacement scenarios.
