4.4.1 Overview
n
The System SLIO motion module FM 054-1CB00 is based largely on the drive profile
CiA 402
.
n
The drive profile
CiA 402
defines state machine, operating modes and objects
(parameters) of components for the drive technology.
n
Here significant objects for control and evaluation of the state machine are
Control
word
,
Status word
and
Operation mode
.
n
Further object serve for configuration and diagnostics of the motion module.
n
All the object are summarized in
Chapter 5 ‘Object dictionary’ on page 96
.
n
The most important objects can be found in
Chapter 4.11 ‘In-/Output area’
n
The access of the objects during runtime happens via
State
machine
- The motion module has a state machine implemented. The status of the
state machine can be controlled by means of commands.
State
change
- The relevant command or any errors cause a state change.
State
- The state is the current state of the state machine. Via the
Status word
‘0x8100-02 - Status word’ on page 110
you can access the state. Here
the state is output via appropriate combinations of bits.
Command
- For triggering of state transitions, certain combinations of bits must be set
in the
Control word
‘0x8100-01 - Control word’ on page 109
combination is called
Command
.
The System SLIO motion module provides its data, such as "Profiling target position" via
an object dictionary. In this object dictionary the objects are organized and addressable a
unique number consisting of
Index
and
Subindex
. The number is specified as follows:
0x
Index (hexadecimal)
-
Subindex (decimal)
Example: 0x8400-03
To improve the structure and for expansion at System SLIO Motion
Module another object numbering (index-assignment) is used besides the
standard CiA 402.
Access to 2 drives
For each drive, there is an object dictionary whose structures are iden-
tical. Please note that the descriptions always relate to drive 1, unless
otherwise noted. To access drive 2, you have to add 0x1000 to the corre-
sponding object.
