Industrial Automation demands components that perform under pressure — and this drive delivers. Contact our team today for pricing, lead time confirmation, and datasheet access.

Technical Specifications & Selection Guide

Selection Note: The 6SE6440-2UD33-0EA1 is the unfiltered variant. For first-environment (residential/light commercial) installations requiring CE Category C2 compliance, an external EMC filter module is mandatory. For filtered versions, refer to the -0FA1 suffix models.

Core Features & Technical Advantages

Robust Sensorless Vector Control — Delivers high dynamic torque response without encoder feedback, reducing hardware complexity while maintaining precision speed regulation across the full load range.

Automatic Motor Adaptation (AMA) — Self-tunes motor parameters at commissioning for optimal efficiency, eliminating manual calibration and reducing setup time on the plant floor.

Flying Restart Capability — Reconnects seamlessly to a spinning motor without mechanical shock, critical for fan and pump applications where coasting loads are common.

Heavy-duty Overload Rating — Withstands 150% overload for 60 seconds and 200% for 3 seconds, protecting both the drive and connected machinery during transient load spikes.

Flexible Communication Architecture — Standard USS/Modbus RTU enables integration with existing SCADA and PLC System networks; optional PROFIBUS-DP module extends compatibility to Siemens S7-300/400 ecosystems.

Adjustable Switching Frequency (2.5-16 kHz) — Allows engineers to balance acoustic noise, thermal performance, and motor cable length requirements for site-specific conditions.

Typical Application Scenarios

✅ Oil & Gas: Pump and compressor speed regulation in upstream and midstream facilities demands drives that withstand harsh ambient conditions and extended duty cycles. The 6SE6440-2UD33-0EA1’s robust construction and wide temperature tolerance make it a reliable Control Module for wellhead and pipeline automation systems.

Power Plants: Cooling tower fans, boiler feed pumps, and auxiliary drives in thermal and hydro power stations require precise speed control and high overload tolerance. This Siemens MICROMASTER 440 drive meets those demands while supporting integration into plant-wide DCS architectures.

✅ Water & Wastewater Treatment: Variable-speed operation of centrifugal pumps and aeration blowers delivers significant energy savings — often 30-50% — compared to fixed-speed operation. The quadratic V/f characteristic is purpose-built for these centrifugal load profiles.

✅ Automotive & General Manufacturing: Conveyor lines, press feeders, and material handling systems benefit from the drive’s fast torque response and multi-parameter-set storage, enabling rapid changeover between production recipes without re-commissioning.

✅ HVAC & Building Automation: Air handling units and chiller pumps in large commercial or industrial facilities achieve energy compliance targets through variable-speed control, with the drive’s USS protocol enabling BMS integration.

Logistics & Professional Service

✅ 2-Day Express Shipping Available — Stocked inventory enables same-day or next-day dispatch to most global destinations. Urgent breakdown orders are prioritized.

✅ 1-Year Warranty — Every 6SE6440-2UD33-0EA1 unit is covered by a full 12-month warranty against manufacturing defects under normal operating conditions. Warranty claims are processed with minimal lead time.

✅ Global Export Compliance — All shipments are prepared with accurate HS codes, commercial invoices, and packing lists to facilitate smooth customs clearance in your destination country.

FAQ — Frequently Asked Questions

Q: What is the price of the 6SE6440-2UD33-0EA1, and do you offer volume discounts?
A: Pricing for the 6SE6440-2UD33-0EA1 varies based on order quantity, destination, and current stock levels. We offer competitive tiered pricing for bulk procurement — contact sale@ninermas.com with your required quantity for a formal quotation within 24 hours. Volume orders of 5+ units typically qualify for preferential rates.

Q: Is this unit 100% Original and Brand New — not refurbished or remanufactured?
A: Yes, absolutely. Every unit we supply is 100% Original and Brand New, sourced from authorized Siemens distribution channels. We do not sell refurbished, repaired, or grey-market products. Factory seals are intact upon delivery.

Q: What is the lead time for the 6SE6440-2UD33-0EA1?
A: In-stock units ship within 1-2 business days. For out-of-stock scenarios, standard lead time is 3-7 business days depending on sourcing location. Emergency breakdown orders are handled with priority processing — contact us directly for expedited options.

Q: Can you provide the official Siemens datasheet and wiring diagram?
A: Yes. The official Siemens MICROMASTER 440 operating instructions and parameter manual are available upon request. Contact our technical team at sale@ninermas.com and reference model 6SE6440-2UD33-0EA1 in your inquiry.

Q: Is this drive compatible with Siemens S7 PLC systems and PROFIBUS networks?
A: The standard unit communicates via USS/Modbus RTU. PROFIBUS-DP connectivity is available through the optional 6SE6400-1PB00-0AA0 communication module, enabling full integration with Siemens S7-300/400 PLC System architectures and TIA Portal engineering environments.

Q: What is the difference between the 6SE6440-2UD33-0EA1 and filtered variants?
A: The 6SE6440-2UD33-0EA1 is the unfiltered version (Class A1), suitable for industrial environments where external EMC filtering is already present or where the installation is not subject to first-environment EMC regulations. Filtered variants carry the -0FA1 suffix and include an integrated Class A EMC filter.
