3.5.16 On-the-fly measurement

This function offers the possibility to save the actual position value on the rising or falling
edge of the digital input DIN9. This actual position value can then be read out for
calculation within a controller, for example.

The function is activated during configuration, and the edge to be monitored is selected.


The On-the-Fly Measurement function supports continuous sampling, i.e. the configured
edge is monitored and the stored actual position values are overwritten with each sample
event.

3.5.17 Endless positioning

For applications such as “synchronised conveyor belt” or rotary indexing table, endless
positioning is possible in one direction via relative positioning records.
No endless positioning is possible in jog mode, since absolute positions are always used
as target here.
For relative position records, an overrun of the position counter is possible. That is, the
position counter jumps from +32767 revolutions to -32768 revolutions, for example.
To be able to use the Endless Positioning function, the following settings must be made
during configuration.
