4 Operation Modes of the Positioning
4.1 General Issues about Operation Modes
The following operation modes are available for positioning. Operation modes:
− Positioning mode. Automatic operation for sequence-controlled and repeatable
approach to different targets in an application. The target can be selected via an
overriding controller (parameter channel of field bus or digital inputs).
−
Homing. A homing operation is performed in order to define a new point of ref-
erence in the system. After a homing operation, the identified point of reference
is used as the basis of all positioning operations.
−
JOG mode. This operation mode enables free moving via digital inputs. This
mode is often used for setup or service purposes.
−
Teach-in mode. Teach-in mode is normally used only during first commissioning
of a plant or after the plant has been retrofitted. In this mode, a current position
can be saved for a motion block in the frequency inverter.
"Positioning Mode" and "Teach-In Mode" are selected via parameter Operation
Mode
