Term/abbreviation Meaning
Homing run The reference position and therefore the source of the basis system of the
axis are defined by a homing run.

Input and/or output
Jog mode Manual positioning in positive or negative direction (only on field bus
variants of the MTR-DCI via the field bus or only with FCT or control panel).
Motor unit Integrated unit consisting of the controller, motor, measuring system and,
if applicable, gears (e.g. motor unit MTR-DCI).
Operating mode Type of controller or internal operating mode of the controller.
– Type of control: Record Select, Direct mode
– Operating mode of the controller: Position profile mode, homing mode,
Demo mode, ...
PLC Programmable logic controller; in brief: controller: (PLC: progammable
logic controller)
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:
– The number of the position set
– The absolute or relative basis of the nominal position
– The nominal position of the position set
– The positioning speed of the position set
Project zero point (PZ) Basis point for all positions in positioning tasks (Project zero point). The
project zero point forms the basis for all absolute position specifications
(e.g. in the position set table or with direct control via the control or diag-
nostic interface). The basis point for the project zero point is the axis zero
point. With the MTR-DCI the project zero point PZ and the axis zero point AZ
are identical.
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. SMT-8 or SIEN) which serves for ascertaining the
reference position and is connected directly to the controller.
Referencing Complete definition of the basis system of the axis with reference point
and, if applicable, zero point.
