Description
The CPUs support the standard Motion Control func-
tions via the technology objects speed axes, positioning
axes, synchronous axes, external encoders, cams, cam
tracks and measuring inputs.
Speed-controlled axis for controlling a drive with
•
speed specification
Positioning axis for position-controlled positioning of
•
a drive
Synchronous axis to interconnect with a master
•
value. The axis follows the synchronous operation
of the position of the leading axis
External encoder for detecting the actual position of
•
an encoder and its use as a master value for syn-
chronous operation
Cams, cam track for position-dependent generation
•
of switching signals
Measuring input for fast, accurate and event-
•
dependent sensing of actual positions
PID Compact (continuous PID controller)
•
PID 3Step (step controller for integrating actuators)
•
PID Temp (temperature controller for heating and
•
cooling with two separate actuators)
