Our most technically advanced inverter drive continues Lenze – AC Tech’s tradition of innovative compact inverter design. The performance and flexibility make the SMVector an attractive solution for a broad range of AC Motor applications and with several communications protocols available, networking drives and components into a system solution can be done now or in the future.

The SMVector NEMA 1 (IP31) is the most common and cost effective drive enclosure for a wide range of applications including packaging, material handling / conveying, positive displacement pumping, and HVAC systems.

The power ranges of the SMVector with NEMA 1 (IP31) include:

  • 200/240V – 1 or 3 Phase Input, up to 3.0 HP (2.2 kW)
  • 400/480V – 3 Phase Input, up to 30 HP (22 kW)

The SMVector Series can be used with 3-phase AC induction motors and is available in NEMA 1 (IP31) , NEMA 4X (IP65) ¹ and NEMA 4X (IP65) ¹ with an integral disconnect switch. Filtered input versions of the SMV are available in NEMA 4X (IP65) models for compliance with the CE EMC directive.

Programmable digital and analog I/O allow the drive to be configured for many application specific tasks such as multiple preset speeds, electronic braking and motor jogging to name a few. Like all Lenze – AC Tech sub-micro drives, the SMVector uses EPM memory technology for fast and efficient programming.

Technical documentation for the SMVector Series Drive, and all AC Tech brand drives, is available in our Technical Library.

¹ type 4X (IP65) enclosures are available for either indoor use, suitable for most indoor industrial environments; or indoor/outdoor use that offers UV protection and has higher impact strength at low temperatures.

For applications in tough environment
SMVector Drives – IP65 frequency inverters

The IP65 SMVector is designed to meet general purpose application requirements.

The IP65 enclosure means that the drive is designed to perform in the harshest of environments, even in areas with high levels of dust or moisture and in areas requiring washdown with low pressure jets. Choose the material of the housing (ABS plastic or Polycarbonate) which suits your application.

SMVector Drives are simple to use. They are easy to program with a integrated keypad – meaning that parameter setting and commissioning takes literally seconds! Impressive and flexible vector performance, a whole array of communication modules for industrial communication and last but not least an available Mains Disconnect option with Lock Off make IP 65 SMVector a very smart and cost effective Solution.

Naturally SMVector Drives are equipped with the unique EPM (Electronic Programmable Module). Parameter setting can be saved on the EPM and copied to other drives as often as required.

Powerful new variable speed drives
L-force Inverter Drives 8400

Precisely tailored to your application – this is what the new Lenze frequency inverter generation stands for. Our customers demanded Rightsizing which made us produce a frequency inverter series where each successive model as BaseLineStateLine, and HighLine builds on the previous one in terms of functionality and drive behaviour. On each and every one, the installation, parameterisation, operation or service are identical. Combined with intelligent features, as provided by the memory module and the online-diagnostics the 8400 drives contribute to process optimisation and more added value in the engineering industry.

Dynamic and precise

Servo systems – drives & motors

Modern systems are often designed in such a way that products can be replaced quickly and without complication. If a high degree of response and accuracy are also required, Lenze’s servo drive systems offer the necessary flexibility. Combined drive controller and servo motor packages featuring perfectly matched components provide solutions for a wide variety of requirements. Compared to mechanical and pneumatic solutions, servo technology is not only more responsive and accurate, but also better value for money and more wear resistant.

Our drive and automation technology is used in a wide variety of industries, for example in materials handling technology, in the packaging industry, the industrial handling sector, the robotics sector and in automotive construction. Our products are carefully co-ordinated and matched and can be combined as required to provide the right solution for your needs. Automation solutions with integrated software and system engineering and a global customer service network complete the offer. Our reliability combines with the quality of our products and services to enable us to increase the productivity of our customers in mechanical engineering and that of machine operators.

We have developed L-force in response to the increasing complexity of applications and processes. As well as being an innovative drive and automation product family, L-force is Lenze’s new and integrated solution portfolio.

The intelligent drive for modular machines
9300 servo inverter

9300 intelligent drives are ideally suited to the independent control of subprocesses within a machine. Taking existing standard applications as a starting point, individual drives can easily be extended with the help of function blocks that can be interconnected as desired; this takes the pressure off the central control and facilitates modular mechanical engineering. The series can be used universally in the power range 0.37 to 75 kW.

In order to meet the most diverse servo technology requirements, four software versions are available:

By using a uniform user interface, the need for training is reduced – once you have learned how to use it, this knowledge will never go to waste. 9000 servo drives can be integrated into current fieldbus systems easily using the pluggable AIF communication module.

The devices are optionally available with the integrated “safe torque off” (safe standstill) function.

A large number of system accessories finish off the entire product range.
