5.5.1 Functions available
The course program allows you to link several position sets in a sequence. These positions
will be approached one after another. Characteristics of the course program:
ƒ Up to 32 course program steps can be selected.
ƒ Both linear sequences which will terminate automatically and ring−shaped linkages
are possible.
ƒ Via a special digital input, it is possible to approach a selectable position within the
course program. The position can be selected via digital inputs.
ƒ For every course program step, you can select up to 2 following positions. They can
be used for branches in the course program. The branches depend on the logical
status of the digital inputs.
ƒ The course program can control two digital outputs. For every course program step,
there are 4 different options (On, Off, Target reached, Remaining path message)
available.
ƒ The course program provides two alternative entry points. The entry points can be
freely parameterised and are started by means of digital inputs. Thus, you can use a
course program with two entries or, alternatively, two smaller course programs with
up to 32 program steps which can be called completely independently of each other.
ƒ The course program can be easily created and monitored by using the
parameterisation interface. The created application will be saved in a parameter set
or, alternatively, in a course program file and can be transferred to other 931E/K
servo positioning controllers.
ƒ The program lines of the course program are processed every 1.6 msec. This ensures
that each output set by the course program will remain set for at least 1.6 msec.
The course program mode is activated via the corresponding option button in the
command window. See the chapter "Activating the operating mode". (

The setting can be permanently saved in the servo positioning controller.
The course program is controlled via the digital inputs. Digital inputs with level (High/Low)
evaluation must remain at the same level for at least 1.6 msec (cycle time of the sequence
control for the course program) to ensure reliable level detection. Edge−sensitive inputs
must be set for at least 100
ms.
