LENZE Vector Frequency Inverters

Why not find out for yourself? We offer seamless standard products with flexible application options, quick and easy start-up, reliability and of course a high level of quality.

The vector is a vector-controlled frequency inverter which is ideally equipped even for complex applications. An excellent drive response – even without the use of speed feedback – and previously unimaginable options for open and closed-loop control tasks are just some of the features which make this frequency inverter so impressive. The integrated flying restart circuit enables the machine to be restarted even if the shaft is still rotating.

Operational reliability An adjustable slip compensation function compensates load-dependent speed deviations without complex speed feedback. The maximum speed limit ensures stable operation at all times with static and dynamic loads.

All connections can be accessed easily from outside the unit. Ready for immediate operation The frequency inverters are preset for standard operation. The following parameters are also preset: User-friendly A wide variety of topic-related and applicationspecific menus are sure to help you solve your drive task and find the parameters required for it. Simple dialogue boxes e. Alternatively, a plug-on operating module is available.

The correct setpoint source for every application — Via setpoint potentiometer on the control current on the control terminals — Via master reference voltage or master reference current on the control terminals — Via vecgor frequency input — Via manuaal operating module — Via a communication module directly from a host system.

Lenze Product information – vector Communication The frequency inverters communicate with a higherlevel host system via plug-on communication modules. This enables for example bus connections to be made between several Lenze inverters and automation components, with little cabling required.

Open and closed-loop control free of charge More than freely connectable function blocks such as PID controllers, flipflops, counters, comparators, delay elements, logic and mathematical functions are available.

This enables the vector to perform other open and closed-loop control functions in addition to the actual drive task in the same way as a PLC. This reduces the load on – or even eliminates the need for – higher-level control systems, free of charge! Furthermore, the freely assignable function blocks mean that the vector can be integrated in machine, system and control concepts easily and without compromise. In order to help us to do this, please make sure you provide the following information: Ex works according to the delivery method specified, excluding packaging.


Use the following pages to help you: Selection of accessories — Motor chokes e. A list of Lenze sales offices can be found on the last two pages or on the Internet www. More frequency inverter types such as the vector range are available for the power range 0. Unshielded m m Max. Motor chokes are an alternative method of reducing shaft currents see page Mr Setting range 1: The components required for parallel connection DC connection kit are included in the scope of supply.

The device should be mounted with a clearance of 50 mm at the side. Master Lenze x x 10 1 Note: Other inverters in the range servo or vector can also be used for the DC supply or DC bus connection in the models shown on these pages. Master Lenze x x The frequency inverter can only be protected using semiconductor fuses utilisation class gRL.

Standard fuses and suitable holders e. LV 20 Semiconductor fuses utilisation category gRL are required to protect the DC cables and the frequency inverter. We recommend the following fuses with appropriate cable cross-sections. LV [V] 20 The same cable cross-sections do not have to be used for the input and output.

When laying out cables, ensure adherence to national and local regulations. Following mechanical installation, the master and slave are connected electrically parallel connection: The bars and corresponding screws are part of the scope of supply DC connection kit.

You must ensure the correct mounting distance between the master and the slave 50 mm in order that the DC connecting bars can be installed without problems. Connecting the control signals The frequency inverter control electronics are located in the master. The control signals are connected to the slave via polarised plug connections. Motor-side connection The motor-side parallel connection can only be made via an inductance at the outputs of the master and slave.

The length of the motor cable determines whether the cable inductance is sufficient or if additional motor chokes are required: Observe the operating conditions of the motor chokes see page This also applies if a DC supply or DC bus connection is being used. In addition, depending on the application, it may also be possible to establish communication with a higher-level host system using plugon communication modules.

This provides a high level of flexibility for various drive and automation tasks. Feedback is required for applications, which require a high level of accuracy, wide setting ranges or holding torques at speed 0. The incremental encoder signal can be output again at the master frequency output for slave drives.

The cables have a connector on one end for connection to the vector. This enables, for example, the precise and speed synchronous control of multiple motor systems. The cable has connectors on both ends for connection to two frequency inverters. The system bus CAN enables the following functions: Therefore, the drive can be put into operation directly after installation. Description A wide variety of topic-related and application-specific menus are sure to help you solve your drive task and find the parameters required for it.


Predefined basic configurations are available for complex applications. This adapter is plugged into the PC parallel port. The relevant drivers are installed automatically. PC system bus converter Type ref.

The quick set-up function enables the entire vectoe to be set up quickly and easily, supported by self-explanatory dialogs. For complex applications, the links between function blocks are stored in predefined basic configurations e. System requirements for GDC Hardware: The Keypad XT is also used for the purposes of status display and error diagnostics.

In addition, its built-in memory can be used to transfer parameters to other inverters. Customised level-specific password protection prevents illegal access. The Keypad XT can also be used on devices from the vector, servo and DrivePLC ranges, as well as on distributed motec motor inverters via diagnosis terminal. To facilitate handling, a connection cable can be used to plug the Keypad XT into a hand-held device so that it can be used as a diagnosis terminal. For the RS interface there is an additional screw terminal for connecting through to the next frequency inverter.

The optical fibre can be easily elnze through an optical fibre socket at the module.

For the host system we offer optical fibre adapters which can be plugged into the interface of the host computer. This module is particularly useful for servicing applications. The DeviceNet fieldbus has been particularly successful in the American and Asian markets. Components which support this protocol are available for various systems e.

Simatic S5 in order to facilitate integration into a control system. Three LEDs are located on the communication module to indicate the communication status.

EJ Optical fibre cable: Two LEDs are located on the communication module to indicate the communication status. For this purpose, the setpoint potentiometer can be connected to the analog control terminals of the vector.

A scale and a rotary knob are also available. Name Setpoint potentiometer Order ref. Motor chokes reduce the voltage slop at the frequency inverter output and therefore the capacitive leakage currents.

This leads to a reduction in the frequency inverter load and parasitic currents and makes it possible to use a long motor cable. The cable capacitances of the motor cable cause leakage currents between the motor phases or to PE.

These currents increase the load on the frequency inverter and this may lead to shut-down on faults. The amount of current is determined by the voltage slope and the chopper frequency of the frequency inverter as well as by the effective capacitances of the motor cable.

Motor chokes should therefore be used on long motor cables. Motor chokes can also be used to reduce currents in motor bearings.
