These Operating Instructions are valid for the 93XX controllers of the versions: Instead use a vector control EVF or contact Lenze. Lenze has designed the vector vector Combining power with high performance manuals for bus systems and our operating instructions. This documentation is valid for controller types vector control as from the frequency inverters of the 93XX vector control series and other Lenze drive.

It comprises an air duct Figure 1which is assembled directly on the frequency inverter heat sink, and an air kenze cover Figure 2. The same cable cross-sections do not have to be used for the input and output.

It is added lenez the value of the brake resistance and has a considerable effect on the total resistance. Motor chokes can also be used to reduce currents in motor bearings. We recommend the following fuses with appropriate cable cross-sections.

Feedback is required for applications, which require a high level of accuracy, wide setting ranges or holding torques at speed 0. Lenze Product information – vector Communication The frequency inverters communicate with a higherlevel host system via plug-on communication modules.

Furthermore, the freely assignable function blocks mean that the vector can be integrated in machine, system and control concepts easily and without compromise.

In the event of low braking power, if necessary, the braking energy may be dissipated either only via the master or only via the slave; in this case use Pmax for the calculation. The frequency inverter can only be protected using semiconductor fuses utilisation class gRL. For complex applications, the links between function blocks are stored in predefined basic configurations e.


Motor chokes reduce the voltage slop at the frequency inverter output and therefore the capacitive leakage currents.

The relevant drivers are installed automatically. The assembly kit is part of the scope of supply.

LENZE Vector Frequency Inverters

Selection of brake resistors The suitable brake resistor must meet the following requirements: This prevents the frequency inverter from setting a pulse inhibit in the event of an overvoltage, which would cause the drive to coast to standstill. This module is particularly useful for servicing applications. The integrated flying restart circuit enables the machine to be restarted even if the shaft is still rotating.

The system bus CAN enables the following functions: The cable has connectors on both vectpr for connection 930 two frequency inverters. Use the following pages to help you: All connections can be accessed easily from outside the unit.

A motor choke is an inductance which is connected to the motor cable at the frequency inverter output. The Keypad XT can also lenae used on devices from the vector, servo and DrivePLC ranges, as well as on distributed motec motor inverters via diagnosis terminal.

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.

The bars and corresponding screws are part of the scope of supply DC connection kit. EJ Optical fibre cable: Therefore, the drive can be put into operation directly after installation.


Unshielded m m Max. Our customers measure the quality of our products. This reduces the load on – or even eliminates the need for – higher-level control systems, free of charge! The vector is a vector-controlled frequency inverter which is ideally equipped even for complex applications.

We offer seamless standard products with flexible application options, quick and easy start-up, reliability and of course a high level of quality. Semiconductor fuses utilisation category gRL are required to protect the DC cables and the frequency inverter. These currents increase the load on the frequency inverter and this may lead to shut-down on faults. The device should be mounted with a clearance of 50 mm at the side. Customised level-specific password protection prevents illegal access.

A list of Lenze sales offices can be found on the last two pages or on the Internet www. Master Lenze x x This provides a high level of flexibility for various drive and automation tasks.

Connecting the control signals The frequency inverter control electronics are located in the master. The Keypad XT is also used for the purposes of status display and error diagnostics.

The following parameters are also preset: In addition, depending on the application, it may also be possible to establish communication with a higher-level host system using plugon communication modules.
