Our drives are reliable in respect of operation, flexible in terms of application, easy to commission and meet high standards of quality. We can provide a solution to suit any requirement in the power range between 0.25 and 400kW.
Precise positioning – Positioning with frequency inverters
The frequency inverter series for process optimisation throughout all phases of the value-added chain.
The range of modular frequency inverters for standard applications with an extensive set of functions.
The flexible frequency inverter for complex applications with user-definable function block structure.
A sensorless vector drive with IP65 enclosure from 0.37 to 7.5kW needing no panel space and suiting wet or dusty environments.
The compact frequency inverter for simple applications with clear functionality.
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:
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.
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.
Drive features
The modular range of 8200 vector frequency inverters in the power range from 0.25 to 90 kW provides a complete and consistent solution with everything you need to facilitate operation, handling, diagnostics and communication. Pluggable function modules can be used to integrate the 8200 vector into the control and automation world of your machine or plant.
The compact dimensions save you space in the control cabinet. For customised cooling concepts, we can offer “push-through technique” and “cold-plate technique” versions. For operation, you can choose to use either the plug-in Keypad XT operating moduleor a PC running the user-friendly Global Drive Control easy operator software, which is available free of charge.
The devices for 400 V mains voltage are optionally available with the integrated “safe torque off” safe standstill) function from 3 kW upwards.
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 BaseLine, StateLine, 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.
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.
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.
