Glossary
A
Axis
An axis is a special type of system module and generally contains at least one
drive controller and a motor but, depending on the application, can contain
further devices such as gearboxes and encoders.
AIF
Abbreviation for "AutomationInterface". Lenze-specific interface on the
controller for plugging on a communication module.
System module
Generic term for a mechatronic unit which can generally include several
devices, one or several networks, information on parameter values, program
logic and documentation.
A system module provides a specific technological function. It interacts with
its environment and can be generally reused in another environment or
system. The interfaces of a system module are provided by the interfaces of its
components.
Controller
Generic term for Lenze frequency inverters, servo inverters and PLCs.
Application
Implementation of a concrete drive solution (e.g. speed control) on an
individual device.
Application variable
Structure of element variables which is communicated via network(s) using a
specific transfer mode. The definition of an application variable is completely
independent of a specific type of network.
B
Bus server
Fieldbus-specific OPC server according to DRIVECOM specification.
C
CAL
Abbreviation for "CAN Application Layer". Communication standard (CiA DS
201-207) which provides the objects, protocols and services for the event or
polling-controlled transfer of CAN messages and the transfer of greater data
areas between CAN nodes. Furthermore, CAL offers powerful processes for an
automatic assignment of message identifiers, the initialisation of network
nodes and the assignment of an individual identification to network nodes.
CAN
Abbreviation for "Controller Area Network". Serial, message-oriented (not
node-oriented) bus system for max. 63 nodes.
CANopen
Communication profile (CiADS301, version 4.01), which has been created
under the umbrella association of the CiA ("CAN in Automation") in
conformance with the CAL ("CAN Application Layer").
CiA
Abbreviation for "CAN in Automation (e. V.)": International manufacturer and
user organisation with the target to worldwide distribute the knowledge of
the internationally standardised CAN bus system (ISO 11898) and promote its
technical further development.
Internet:
COM
Abbreviation for "Component Object Model": Architecture developed by
Microsoft ® for the co-operation of individual executable software
components (objects) which communicate with each other in a similar
manner and are not connected until the program is running.
Controller
A Lenze Controller is the central control unit of the "Controller-based
Automation" automation system. This enables the machines to be centrally
controlled and/or visualised. The "Controller-based Automation" is Lenze's
central control technology.
