Overview
Function module basic positioner (EPos)
The basic positioner EPos is available as a standard technology
function on all SINAMICS S120 Control Units and can be called
as a function module that can be activated additionally. The
basic positioner can be used to resolve basic motion control
tasks without additional external technological outlay from the
drive itself.
Integrated functionality for absolute and relative positioning
of linear and rotary axes with motor encoders or machine
encoders.
The basic positioner Epos in the SINAMICS S120 drive system
provides powerful and precise positioning functions. 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, and the comprehensive monitoring
functions are outstanding.
Many applications can be carried out without external position
controllers.
The EPos basic positioner is used to position linear and rotary
axes (modulo) in absolute/relative terms with rotary as well as
linear motor encoder or machine encoder (indirect or direct
measuring system).
EPos is a function module that can be activated additionally in
Servo Control and in Vector Control.
User-friendly configuring and commissioning including control
panel (operation using PC) and diagnostics with the STARTER
commissioning tool.
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.
