/in , , /by

All AC Tech SMVector drives come equipped with a default password to protect the drive from operators changing parameters without the programmers consent. Although this process can be confusing the first time you open your AC Tech SMVector VFD, or Variable Frequency Drive, it is easy to do once you’ve done it once.

Password protection is becoming more and more prominent in the world of Variable Frequency Drives and the SMVector illustrates this process right out of the box. The purpose of protection is to keep the program within the drive protected from outside modifications or to allow OEMs to protect their proprietary configurations when selling a machine.

Many customers also opt to purchase a EPM module for their SMVector drive to keep their configuration files backed up to a separate module, just in case of a drive failure or EPM program failure. Whatever the reason for accessing the parameters, the process of accessing the parameter menu is extremely easy.

How To Wire 120 Volt Input To An SMVector VFD Drive

/in , /by

The SMVector series of drives supports input voltages up to 600 volts. Although these voltages are pretty much the standard in the US, many people do not realize the differences in wiring between single phase and three phase. One of the slightly deceptive configurations in the 120 Volt SMVector drive is that it shows and L1 and L2 input but the hot wires are actually only wired to L1 and N.

Wiring the SMVector series drive is a simple enough process, but the proper safety precautions should always be taken to ensure injury or death do not occur. For this reason, it is ultimately the responsibility of the one performing to work to take the proper precautions as designated by their local safety laws and regulations.

Abstract:

This article illustrates how to wire an SMVector series drive for 120 volts main supply input. It also illustrates how to determine what voltage the SMVector drive is rated for.

Note: This tutorial and task should only be performed by a qualified drives specialist.

How To Wire 120 Volt Input To An SMVector VFD Drive:

Before You Begin: Make sure the drive’s input voltage rating is rated for 120 Volts AC by looking at the drives nameplate (the demonstration image below shows input voltage of 400/480 V 3 phase).

Note: 240 Volt Drives can be powered with 120 Volts but the wiring will be different and the drive must be derated for the application. Contact us for more details.

Before You Begin - Make Sure The Drives Input Voltage Is 120 Volts (or 240 Volts if you are Derating the drive)

1. Make sure the mains power supply you will be wiring has been completely shut off and locked out.

2. Note the manuals wiring diagram for wiring 120 Volt single power phase to an SMVector drive. To protect your drive, it is recommended that you properly fuse the hot line coming into your L1 input.

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.
