4.5 Control and feedback interface

4.5 Control and feedback interface
Direct access to the control and feedback interface is not needed for use of the module in an
S7-1500 or S7-1200 system. For this case an S7-1500 system has the TO_SpeedAxis,
TO_PositioningAxis and TO_SynchronousAxis technology objects, and an S7-1200 system
has the TO_PositioningAxis technology object. For a detailed description of configuring the
technology module with the axis technology objects, see Function Manual S7-1500T
Motion Control, section "Configuring", which is available for download on theInternet
(https://support.industry.siemens.com/cs/ww/en/view/109481326).
The control and feedback interface of the channels is a partial implementation of the
PROFIdrive interface "frame 3". Additional information on using the control and feedback
interface is available in the section Configuring (Page 26).
