Machine Data, Modes and Traversing Programs

The IP 266 can execute positioning operations only when it has correct machine
data at its disposal. You cannot start a positioning operation until you have
provided the IP with this data.
The machine data and all permissible parameters are discussed in detail in
Section 5.1. In Section 6, you will find information on how to enter these values
and transfer them to the IP 266.
5.1

Machine Data

The machine data describes the properties of
• the drive system,
• the position encoder,
• and the position controller.
The IP 266 needs machine data in order to compute the correct speed and path.
Errored data can therefore result in an unpredictable or incorrect system
response.
You can also enter machine data values for coordinate shifts and corrections
which are needed, for instance, if tool dimensions change.
Table 5-1 shows you which items of machine data you need for different tasks.
The table also provides cross-references to the sections describing these data
items.
