Function block A function block can be compared with an integrated circuit that contains a
certain control logic and delivers one or several values when being executed.
• Each function block has a unique identifier, e.g. "L_MPot_1" (motor
potentiometer function)
DC injection brake The DC injection brake is to brake and/or hold the motor. For this purpose, the
8400 motec creates a quasi DC field at the stator of the asynchronous machine.
The energy to be dissipated is converted into heat in the rotor.
Holding brake The holding brake serves to hold the rotor by means of a mechanical unit.
Diagnosis terminal / keypad The diagnosis terminal combines the keypad with a housing and a connecting
cable. The diagnosis terminal serves to check or change individual settings. In a
quick commissioning menu, the inverter can be parameterised in the basic
settings by means of the diagnosis terminal.
Note: If this documentation contains descriptions of settings with the keypad,
use the diagnosis terminal instead for the 8400 motec, since the keypad cannot
directly be plugged into the diagnostic interface of the 8400 motec.
LA Abbreviation: Lenze Application block
• Example: "LA_NCtrl" – block for the "actuating drive speed" application.

Subcode If a code contains several parameters, they are stored in "subcodes".
This Manual uses a slash "/" as a separator between code and subcode
(e.g. "C00039/1").
This term is also referred to as "subindex" in common parlance.
System block In the application, system blocks provide interfaces to basic functions and to the
hardware of the inverter (e.g. to the digital inputs).
USB diagnostic adapter The USB diagnostic adapter is used for the operation, parameterisation, and
diagnostics of the inverter. Data are exchanged between the PC (USB
connection) and the inverter (diagnostic interface on the front) via the
diagnostic adapter.
• Order designation: E94AZCUS
VFCplus Motor control: V/f characteristic control ("Voltage Frequency Control")
VFCplusEco Motor control: V/f characteristic control - energy-saving
In this motor control mode, the inverter adapts the motor voltage to the
requirements of the load. Especially at speeds lower than 50 % of the rated
speed and a reduced torque, losses in the motor and in the inverter can be
reduced. Hence, the usually bad efficiency of the drive in the partial load
operational range is significantly increased.

2 Introduction: Parameterising the inverter
Being a component of a machine which includes a speed-variable drive system, the inverter needs
to be adjusted to its drive task and the motor. The inverter is adjusted by changing parameters
which are saved in the memory module. The parameters can be accessed by keypad (diagnosis
terminal), by »EASY Starter« or by the »Engineer«. Access is also possible by a master control via
fieldbus communication. For this purpose, various communication units are available, e.g. AS-i,
CANopen, and PROFIBUS.
Danger!
In general, changing a parameter causes an immediate response in the inverter!
• This may lead to an undesirable response at the motor shaft when the inverter has
been enabled!
• Setpoint sources, for instance, may switch over all of a sudden (e.g. when configuring
the signal source for the main setpoint).
Certain device commands or settings which may cause critical states of drive behaviour
constitute exceptions. Such parameter changes are only possible if the inverter is
inhibited. Otherwise, a corresponding error message will be issued.

2.1 Integrated technology applications
The following technology applications integrated in the inverter 8400 motec provide the main
signal flow for the implementation of a general or a special drive solution:
Technology application "Actuating drive speed"
This preset technology application serves to solve speed-controlled drive tasks, e.g.
conveyor drives (interconnected), extruders, test benches, vibrators, travelling drives,
presses, machining systems, metering units.
Technology application "actuating drive speed (AC Drive profile)"
This technology application available from version 04.01.00 provides a speed and
torque control by means of "AC Drive Profile". For this purpose, the Communication
Unit EtherNet/IP™ is required.
"Switch-off positioning" technology application
This technology application available from version 05.00.00 is used to solve speed-
controlled drive tasks which require a pre-switch off or stopping at certain positions,
e.g. roller conveyors and conveying belts. The pre-switch off is implemented by
connecting switch-off sensors.
Detailed information on each technology application can be found in the main chapter
entitled "Technology applications". (220)

2.2 Selection of the appropriate commissioning tool
There are several possibilities for commissioning the 8400 motec inverter:
Tip!
The Engineering tools »EASY Starter« and »Engineer StateLevel« are provided free of charge
in the internet:
http://www.Lenze.com Download Software downloads
For communication between PC and inverter, the USB diagnostic adapter can be used for
instance (see the following subchapter).
Commissioning via keypad X400 (or diagnosis terminal X400)
The keypad is an alternative to the PC for the local operation, parameterisation, and
diagnostics in a simple manner. The keypad is especially suited for test and
demonstration purposes and for the case that only few parameters have to be
adapted.
Note:
• Use the diagnosis terminal for the 8400 motec inverter. The diagnosis terminal
combines the keypad with a housing and a connecting cable.
• The description how to make the settings with the keypad also applies to the
diagnosis terminal.
Commissioning with PC and »EASY Starter«
The »EASY Starter« is a Lenze tool for easy online diagnostics, parameter setting and
commissioning of the inverter.
Commissioning with PC and »Engineer«
The »Engineer« is a Lenze engineering software for parameter setting across all
devices, configuring and diagnosing individual components (as for instance inverters,
industrial PCs, motors, I/O systems) and machine control systems.

2.2.1 Overview: Accessories for commissioning
Fast communication via diagnostic interface
From version 06.01.00, the diagnostic interface also supports the fast communication with
57,600 Baud (instead of 4,800 Baud).
• If no read or write access takes place via the diagnostic interface for 3.5 s, it is changed over to
normal communication again with 4,800 Baud.
• 57,600 Baud are only possible if the 8400 motec comes with the fast diagnostic interface and
an »Engineer« from version 2.19 or a keypad from firmware version 4.2 is connected.
• The current baud rate of the diagnostic interface is displayed in C01905.
