IP 266

Preface

The IP 266 is a powerful intelligent I/O "positioning" module that was developed
specially for installation in the S5-100U programmable controller. The IP 266
makes it possible to operate servomotors via power electronics equipment. The
IP 266 can be used in conjunction with the following CPUs:
• CPU 100 (6ES5 100-8MA02 only)
• CPU 102 (without restriction)
• CPU 103 (without restriction)
The IP 266 provides numerous functions for both open-loop and closed-loop
positioning. These functions are described in detail in the section entitled Modes.
The IP 266 provides modes for
• positioning
• coordinate shift and
• correction (compensation)
All modes can be used both separately and as a consequence of individual
functions in machining programs.
The complex open-loop and closed-loop procedures which a standard pro-
grammable controller must perform in order to carry out a positioning task
require a great deal of processor time.
The IP 266 can considerably reduce the amount of processor time needed because
it takes over the entire positioning process.
Your control program can thus execute in parallel with the positioning
procedure.
Sequences of motions involving several axes are made possible by the use of
additional IP 266 modules.
Sequencing control can be implemented via the IP 266's digital inputs and
outputs.
Because this module can be installed only in an S5-100U programmable
controller, it has been assumed that the reader is well acquainted with the
S5-100U product manual. The fundamentals of STEP 5 programming are not a
topic of discussion in this manual.
