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.

We recommend the following fuses with appropriate cable cross-sections. Semiconductor fuses manuzl category gRL are required to protect the DC cables and the frequency inverter.
U1, V1, W1 a1 a Note: A list of Lenze sales offices can be found on the last two pages or on the Internet www. This also applies if a DC supply or DC bus connection is being used.

This reduces the load on – or even eliminates the need for – higher-level control systems, free of charge! Braking is always controlled when using an external brake resistor.
Our product range includes frequency inverters, power converters, variable speed drives, rocker gears and speedtransforming gears, as ,anual as brakes and clutches. 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.
Install the motor choke as close as 930 to the frequency inverter. Feedback is required for applications, which require a high level of accuracy, wide setting ranges or holding torques at speed 0. The integrated flying restart circuit enables the machine to be restarted even if the shaft is still rotating.
Furthermore, the freely assignable function blocks mean that the vector can be integrated in machine, system and control concepts easily and without compromise.
Motor chokes are an alternative method of reducing shaft currents see lezne In addition, its built-in memory can be used to transfer parameters to other inverters.
LENZE Vector Frequency Inverters
All connections can be accessed easily from outside the unit. The components required for parallel connection DC connection kit are included in the scope of supply.
Predefined basic configurations are available for complex applications. 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. In addition, depending on the application, it may also lezne possible to establish communication with a higher-level host system using plugon communication modules. Therefore, the drive can be put into operation directly after installation. The following parameters are also preset: Extensive installation guidelines are mabual to facilitate the assembly process.
The cable capacitances of the motor cable cause leakage currents between the motor phases or to PE. Do not undercut the minimum permissible value!
The DeviceNet fieldbus has been particularly successful in the American and Asian markets. This module is particularly useful for servicing applications. 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.
The assembly kit is part of the scope of supply. The vecror has connectors on both ends for connection to two frequency inverters. These currents increase the load on lsnze frequency inverter and this may lead to shut-down on faults.

Master Lenze x x This enables the vector to perform other open and closed-loop control functions in addition to fector actual drive task in the same way as a PLC.
Alternatively, a plug-on operating module is amnual. Company Street Order ref. Selection of accessories — Motor chokes e. For this purpose, the setpoint potentiometer can be connected to the analog control terminals of the vector. The system bus CAN enables the following functions: Simple dialogue boxes e.
This enables for example bus connections to be made between several Lenze inverters and automation components, with little cabling required. Selection of brake resistors The suitable brake resistor must meet the following requirements: 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. Following mechanical installation, the master and slave are connected electrically parallel connection: 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.
LV [V] 20 Lenze Product information – vector Communication The frequency inverters communicate with a higherlevel host system via plug-on communication modules. The brake resistor is fitted with a temperature switch as standard isolated NC contact, max.
The incremental encoder signal can be output again at the master frequency output for slave drives. U, V, W Output: The frequency inverter can only be protected using semiconductor fuses utilisation class gRL.
Components which support this protocol are available for various systems e. It is added to the value of the brake resistance and has a considerable effect on the total resistance.

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. 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.
A motor choke is an inductance which is connected to the motor cable at the frequency inverter output. Two LEDs are located on the communication module to indicate the communication status.
