1.3 Terminology used
Term Meaning
»Engineer« Lenze PC software which supports you in "engineering" (parameterisation, diag-
nostics and configuration) throughout the whole life cycle, i.e. from planning to
maintenance of the commissioned machine.
Application A technology application is a drive solution equipped with Lenze's experience
and know-how in which function and system blocks interconnected to a signal
flow are the basis for implementing typical drive tasks.
ASM Asynchronous motor
CINH Abbreviation: Controller inhibit (pulse inhibit)
Code Parameter used for controller parameterisation or monitoring. The term is usu-
ally called "index".
DC-injection braking DC injection braking is to brake and/or hold the motor. For this purpose, the
8400 BaseLine C creates a quasi DC field at the stator of the asynchronous ma-
chine. The energy to be dissipated is converted into heat in the rotor.
DCTRL Abbreviation: Drive control (device control)
Display code Parameter that displays the current state or value of an input/output of a sys-
tem block.
EPM Memory module on which all parametes of the drive system are saved non-vola-
tilely. These include the parameters of the controller and communication-rele-
vant parameters for the communication unit used.
Function block A function block can be compared with an integrated circuit that contains a cer-
tain control logic and delivers one or several values when being executed.
• Each function block has a unique identifier, e.g. "L_MPot_1" (motor potentio-
meter function)
Holding brake The holding brake serves to hold the rotor by means of a mechanical unit.
LA Abbreviation: Lenze Application block
• Example: "LA_NCtrl" – block for the "actuating drive speed" application.
Lenze setting This setting is the default factory setting of the device.
LP Abbreviation: Lenze Port block
• Example: "LP_Network_In" – port block for fieldbus communication.
LS Abbreviation: Lenze System block
• Example: "LS_DigitalInput" – system block for digital input signals.
MCTRL Abbreviation: Motor control
Port block Block for implementing the process data transfer via a fieldbus
QSP Quick stop ("Quick stop):
The motor control is decoupled from the setpoint selection and within a parame-
terisable deceleration time, the motor is brought to a standstill (n
act
=0).
Service brake The service brake serves to shutdown rotary or translatory masses in motion in
a controlled manner. The energy to be dissipated in this process is converted into
heat in the form of friction energy. This process is a regular and recurring opera-
ting mode.
SLVC Motor control: Sensorless vector control ("SensorLess Vector Control")
SM Synchronous motor
Subcode If a code contains several parameters, the individual parameters are stored un-
der "subcodes".
This manual uses a slash "/" as a separator between code and subcode
(e.g. "C118/3").
The term is usually called "subindex".
System block In the application, system blocks provide interfaces to basic functions and to the
hardware of the controller (e.g. to the digital inputs).
