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.

When laying out cables, ensure adherence to national and local regulations.
A motor choke is an inductance which is connected to the motor cable at the frequency inverter output. 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 digital frequency input — Via the operating module — Via a communication module directly from a host system.
This adapter is plugged into the PC parallel port. The system bus CAN enables the following functions: LV 20 For this purpose, the setpoint potentiometer can be connected to the analog control terminals of the vector. This module is particularly useful for servicing applications. U1, V1, W1 a1 a Note: Unshielded m m Max.
Lenze 9300 vector frequency inverter 110 … 400 kW
LV mankal 20 This makes Lenze the ideal supplier for your applications not only for individual components, but also for complete drive systems, from project planning to setup and commissioning. Selection of brake resistors The suitable brake resistor must meet the following requirements: Company Street Order ref. Feedback is required for applications, which require a high level of accuracy, wide setting ranges or holding torques at speed 0. The Keypad XT can also be used on devices from the vector, servo and Vetor ranges, as well as on distributed motec motor inverters via diagnosis terminal.
LENZE Vector Frequency Inverters
This enables for example bus connections to be made between several Lenze inverters and automation components, with little cabling required. Use the following pages to help you: Install the motor choke oenze close as possible to the frequency inverter.
Our product range includes frequency inverters, power converters, variable speed drives, rocker gears and speedtransforming gears, as well as brakes and clutches. Therefore, the drive can be put janual operation directly after installation. We offer seamless standard products with flexible application options, quick and easy start-up, reliability and of course vevtor high level of quality. The maximum speed limit ensures stable operation at all times with static and dynamic loads.
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. For complex applications, the links between function blocks are stored lenzd predefined basic configurations e. The components required for parallel connection DC connection kit are included in the scope manuzl supply. The frequency inverter has a heat sink fan which dissipates the heat outwards via the air lock.
Three LEDs are located on the communication module to indicate the communication status. The following parameters are also preset: Observe the operating conditions of the motor chokes manul page We recommend the mqnual fuses with appropriate cable cross-sections. System requirements for GDC Hardware: The brake transistor integrated in the vector frequency inverter as an option connects the external brake resistor when the DC bus voltage exceeds a certain switching threshold.
In addition, its built-in memory can be used to transfer parameters to other inverters. Our customers measure the quality of our products. The length of the motor cable determines whether the cable inductance is sufficient or if additional motor chokes are required: Predefined basic configurations are available for complex applications.
Components which support this protocol are available for various systems e. For the host system we offer optical fibre adapters which can be plugged into the interface of the host computer.
Name Setpoint potentiometer Order ref. A scale and a rotary knob are also available. Simple dialogue boxes e. The brake resistor converts mechanical braking energy into heat. PC system bus converter Type ref.
It comprises an air duct Figure 1which is assembled directly on the frequency inverter heat sink, and an air vectoe cover Figure 2. The brake resistor is fitted with a temperature switch as standard isolated NC contact, max.
Master Lenze x x Motor chokes should therefore be used on long motor cables. The integrated flying restart circuit enables the machine to be restarted even if the shaft is still rotating. The assembly kit is part of the scope of supply. This leads to a reduction in the frequency inverter load and parasitic currents and makes it possible to use a long motor cable.
Braking is always controlled when using an external brake resistor. It is our responsibility to meet their requirements. Motor chokes reduce the voltage slop at the frequency inverter output and therefore the capacitive leakage currents.
