Drive Mechatronic unit which serves a certain purpose and can be provided with
mechanical, electrical and logical interfaces with regard to its environment. A
device is called a "communication-capable device" if it is able to communicate
as a node in a network.
Unlike the mechatronic unit "system module", a device already is created by
the manufacturer and not only when a system of a concrete project is created.
Examples of devices: drive controllers, PLCs, motors, gearboxes, sensors, en-
coders
DriveServer Lenze software which provides an easy integration of drives into open auto-
mation structures based on OPC ("OLE for Process Control").
OPC
E

the respective device.

F
FIF Abbreviation for "Function Interface". Lenze-specific interface at the controller
which can be plugged onto a function module.
