2 Basic Information on SERVOPACKs
2.1 Overview
This chapter provides information required to select SERVOPACKs, such as SERVO-
PACK models and combinations with Servomotors.
2.2 The Σ-7 Series
The Σ-7-series SERVOPACKs are designed for applications that require frequent high-
speed and high-precision positioning. The SERVOPACK will make the most of machine
performance in the shortest time possible, thus contributing to improving productivity.
2.3 Introduction to PROFINET
2.3.1 Overview
PROFINET (acronym for PROcess FIeld NETwork) is an industry technical standard for
data communication over Industrial Ethernet, designed for collecting data from, and con-
trolling, equipment in industrial systems, with a particular strength in delivering data under
tight time constraints (on the order of 1 ms or less). The standard is maintained and sup-
ported by Profibus & Profinet International, an umbrella organization headquartered in
Karlsruhe, Germany.
The PROFINET Communications Reference SERVOPACKs implement the PROFIdrive
drive profile for communications.
Basic position and speed control are supported along with synchronized position and
speed. You can select the type of control to match your system from basic positioning to
high-speed, high-precision path control.
You can also use PROFINET communications to control the high-level servo control per-
formance, advanced turning functions and many actuators of the Σ-7 Series.
