Term/abbreviation Meaning
Operating mode Type of controller or internal operating mode of the controller.
Ĉ Type of control: Record Select, Direct mode
Ĉ Operating mode of the controller: Position profile mode,
Homing mode, Demo mode, ...
PLC Programmable logic controller; in brief: controller
(also IPC: industrial PC).
Positioning mode
(Profile position mode) Operating mode for processing a position set or a direct positioning
task.
Position set Positioning command defined in the position set table, consisting of
target position, positioning mode, positioning speed and accelerations.
Project zero point (PZ) Measuring reference point for all positions in positioning tasks (Project
zero point). The project zero point forms the basis for all absolute posiĆ
tion specifications (e.g. in the position set table or with direct control via
the controller interface or diagnostic interface). The basis point for the
project zero point is the axis zero point.
Reference point (REF) Basis point for the incremental measuring system. The reference point
defines a known orientation or position within the positioning path of
the drive.
Reference switch External sensor (e. g. type SMT−10) which serves for ascertaining the
reference position and is connected directly to the controller.
Reference travel The reference position and therefore the source of the measuring
reference system of the axis will be defined by the reference travel.
Referencing
(Homing mode) Operating mode in which reference travel is carried out.
Referencing method Method for defining the reference position: against a fixed stop
(overcurrent/speed evaluation) or with reference switch.
SLTE... Type designation, electric slide.
