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.

Ex works according to the delivery method specified, excluding packaging.

Simple dialogue boxes e. 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.

Therefore, the drive can be put into operation directly after installation. Lenze Product information – vector Communication Vectr frequency inverters communicate with a higherlevel host system via plug-on communication modules.

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. PC system bus converter Type ref.

LV [V] 20 The length of the motor cable determines whether the cable inductance is sufficient or if additional motor chokes are required: 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.


Furthermore, the freely assignable function blocks mean that the vector can be integrated in machine, system and control concepts easily and without compromise. These currents increase the load on the frequency inverter and this may lead to shut-down on faults.

The control signals are connected to the slave via polarised plug connections. The components required for parallel connection DC connection kit are included in the scope of supply. Motor chokes are an alternative method of reducing shaft currents see page Feedback is required for applications, which require a high level of accuracy, wide setting ranges or holding torques at speed 0. 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.

U1, V1, W1 a1 a Note: It comprises an air duct Figure 1which is assembled directly on the frequency inverter heat sink, and an air lock cover Figure 2. The Keypad XT is also used for the purposes of status display and error diagnostics.

The bars and corresponding screws are part of the scope of supply DC connection kit. The brake resistor converts mechanical braking energy into heat. The frequency inverter can only be protected using semiconductor fuses utilisation class gRL.

Do not undercut the minimum permissible value!


The integrated flying restart circuit enables the machine to veftor restarted even if the shaft is still rotating. 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 vechor cause the drive to coast to standstill.

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

Figure 1 Figure 2 Note: Alternatively, a plug-on operating module is available. When laying out cables, ensure adherence to national and local regulations. The DeviceNet fieldbus has been particularly successful in the American and Asian markets.

It is our responsibility to meet their requirements. This reduces the load on – or even eliminates the need for – higher-level control systems, free of charge! Selection of accessories — Motor chokes e. Semiconductor fuses utilisation category gRL are required to protect the DC cables and the frequency inverter.

It is added to the value of the brake resistance and has a considerable effect on the total resistance. LV 20 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.
