SMV-Part-Number-Designation.png

How To Interpret The AC Tech SMVector Part Number

/in , /by

Anyone who has spent a fair amount of time working with catalogs and price books understands that each company designates their part numbers differently. Lenze / AC Tech does this in a very intuitive way for their SMVector series of AC Drives. This allows support specialists and field techs to quickly identify hardware in the field.

The importance of a clear part number designation cannot be undervalued. Many times randomized part numbers can be used making it difficult to adequately specify a replacement for an existing unit. Lenze / AC Tech created an all encompassing solution by breaking up the part number into four separate categories: Power Rating, Communications, Input Voltage, Input Phase, Input Line Filter and Enclosure.

Abstract:

This article illustrates how to interpret the part number on any Lenze / AC Tech SMVector drive.

How To Interpret The AC Tech SMVector Part Number:

 

1. When looking at the nameplate of your AC Tech SMVector drive, you will notice the part number is designated under the category of Type: as shown in section B of the image below.

SMV Nameplate Overview and Designation

2. The SMVector Drive part number is broken up into the following 7 different categories: Power Rating, Communications Module, Input Voltage, Input Phase, Input Line Filter and Enclosure.

SMV Part Number Designation

3. If we take the sample part number from Step 1 (ESV751N04TXB), we interpret the following information about the drive based upon the SMV Number Type Designation

  • ESV SMVector Series Drive
  • 751 0.75 kW (or 1 HP)
  • N0 No Extra Communication Installed, Standard Keypad
  • 4 400 / 480 VAC
  • T Three Phase Input Only
  • X No EMC Filter / No Disconnect Switch
  • B NEMA 1 / IP31; Indoor only

4. For many, just the part number from Lenze / AC Tech offers a massive amount of information about the device allowing for extended support on product replacements and alternatives.

Conclusion:

The Lenze / AC Tech part number is a great tool to have on hand. It is important to note that external communications can be purchased separately and the option for communications may not actually reflect what is being used in the field. For this reason, it is extremely important to gather additional information on top of the standard nameplate information when troubleshooting the drive.
