C
COB-ID: Communication object identifier.
Consistency: A data range which is defined as consistent is transmitted complete, i.e. in one bus
cycle.
Controller: Control electronics which evaluate the control signals and provide the voltage supply for
the motor via the power electronics (power electronics + controller + positioning controller).
E
EDS file: Electronic data sheet which describes the functions and features of a CANopen device in
standardised form.
F
Festo Configuration Tool (FCT): Commissioning software with uniform project and data
management for all supported device types. The special requirements of a device type are
supported with the necessary descriptions and dialogs by means of plug-ins.
Festo Handling and Positioning Profile (FHPP): Uniform fieldbus data profile for positioning
controllers from Festo.
Festo Parameter Channel (FPC): FHPP-specific parameter channel version.
FHPP: Uniform fieldbus data profile for positioning controllers from Festo (Festo Handling and
Positioning Profile).
FPC: FHPP-specific parameter channel version (Festo Parameter Channel).
G
GSD file: Device master data file in which all specific features of the slave are saved (e.g. number of
I/Os, number of diagnostic bytes, etc.).
H
Homing: Homing defines the reference position and thereby the origin of the measuring reference
system of an axis.
Homing method: Method for defining the reference position: against a fixed stop (overcurrent/speed
evaluation) or with reference switch.
Homing mode: Operating mode in which homing is carried out.
J
Jog mode: Manual movement in positive or negative direction.
N
Node ID: Used for unique identification of a bus station.
P
PDO: Process Data Object.
PKE: Integral part of the parameter channel (PKW) which contains the task and reply identifiers (AK)
and the parameter number (PNU).
PKW: Telegram part used for transmitting parameters. PKW refers to a parameter identification value
(see also "Festo Parameter Channel (FPC)").
