1.3.1  Technology objects for motion control 
Figure 1-1 Technology objects of the S7-1500 – motion control 
 
 
  Speed axis (TO_SpeedAxis) 
The "speed axis" (TO_SpeedAxis) technology objects presents the mechanical 
drive component in the controller. Jobs for specifying the speed of the drive 
can be placed using PLCopen motion control instructions. 
  Positioning axis (TO_PositioningAxis) 
The "positioning axis" (TO_PositioningAxis) technology object displays the 
mechanical drive component in the controller. Through the user program 
positioning jobs can be placed using PLCopen motion control instructions. 
  Synchronous axis (TO_SynchronousAxis) 
The "synchronous axis" (TO_SynchronousAxis) technology object includes all 
functions of the "positioning axis” technology object. In addition, the 
"synchronous axis” technology object can follow the motions of a master axis. 
Positioning axes as well as synchronous axes can be used as master axis. 
  External encoder (TO_ExternalEncoder) 
The "external encoder" (TO_ExternalEncoder) technology object records the 
actual position of an externally controlled drive. The determined actual 
positions can be evaluated in the user program. 
  Cam (TO_OutputCam) 
The "cam” (TO_OutputCam) technology object generates switching signals 
depending on the setpoint or actual position of an axis or external encoder. 
The switching signals can be evaluated in the user program or output via the 
digital outputs. The switching signals of several cams can be interconnected 
with each other via AND or OR links. 
  Cam track (TO_CamTrack) 
The "cam track" (TO_CamTrack) technology object combines up to 32 
individual cams to one cam track. The start and end position of the individual 
cams can be freely selected. Other parameters are valid for all individual cams.
