P-0-4083, Field bus: length of parameter channel
•
P-0-4084, Field bus: profile type
I/O Mode
Brief Description
•
The drive is operated in "positioning block mode without lag error with
encoder 1" (see also "Positioning Block Mode" in chapter "Operating
Modes").
•
In this operating mode, 64 programmable positioning blocks can be
selected and started via 6 bits (in the 16 bit wide control word).
•
The jog function can be activated in
P-0-4068, Field bus: control
word IO
. As the 1
st
secondary operating mode, "drive-controlled
positioning" was set (see also "Drive-Controlled Positioning" in chapter
"Operating Modes").
•
For PROFIBUS-DP it is possible to activate an optional parameter
channel with
P-0-4083, Field bus: length of parameter channel
(a
maximum of 6 words). (default: P-0-4083 = 0
→
without parameter
channel)
•
In the I/O mode each real-time channel consists of at least one word
(16 bits), the field bus control word (P-0-4068) and the signal status
word (S-0-0144).
In the real-time channel of the field bus the data configured in
P-0-4081,
Field bus: config. list of cyclic command value data ch.
are
transmitted from master to drive.
Parameters

P-0-4068, Field bus: control word IO

In the real-time channel of the field bus the data configured in
P-0-4080,
Field bus: config. list of cyclic actual value data ch.
are transmitted
from drive to master.

Note:
The content of parameter
P-0-4068, Field bus: control word
IO
is only relevant for profile type "I/O mode"
(P-0-4084 = 0xFF82).
The bits in parameter
P-0-4068, Field bus: control word IO
are fixed by
Bosch Rexroth and cannot be changed by the user. If additional control
bits should be required, the parameter
S-0-0145, Signal control word
has to be configured accordingly and transmitted to the real-time channel
of the field bus.
