The positioning functions are only available in the CU250S-2
Control Unit and are functionally identical to the positioning func-
tionality of SINAMICS S110. Due to its flexibility and adaptability,
the basic positioner can be used for a wide range of positioning
tasks.
The functions are easy to handle both during commissioning
and during operation. Furthermore, they are characterized by
their comprehensive monitoring functions.
Many applications can be carried out without external position
controllers.
The EPos basic positioner is available as an additional function
module that can be activated, and is used for the absolute/
relative positioning of linear and rotary axes (modulo) with both
rotary and linear motor encoders (indirect measuring system).
User-friendly configuring and commissioning including control
panel (operation using PC) and diagnostics with the STARTER
commissioning tool V4.3 or higher.
In addition to extremely flexible positioning functions, EPos
offers a high degree of user-friendliness and reliability thanks
to integral monitoring and compensation functions.
Different operating modes and their functionality increase
flexibility and plant productivity, for example, by means of
"on-the-fly" and bumpless correction of the motion control.
Preconfigured PROFIdrive positioning frames are available
which, when selected, automatically establish the internal
"connection" to the basic positioner.
