Note:
The data for the field bus status word refer to the I/O mode
with block acknowledgment (default configuration).
Notes on Parameterization/Commissioning
The following settings are made in the I/O mode as default setting:
•
Fixed real-time channel length of 2 bytes. Thus the length of the cyclic
data channel is (P-0-4082 = P-0-4071 = 2)!
•
Bits
0...5 of
P-0-4051
,
Positioning block acknowledgment
are
copied to bits 8...13 of
S-0-0144, Signal status word
.
•
In the real-time channel only
P-0-4068, Field bus: control word IO
and
S-0-0144, Signal status word
are transmitted.
Note:
With this profile selection, the functional compatibility to the
DKC3.1 drive controllers is established!
Control units that process the real-time data in Motorola format
have the high byte and low byte interchanged compared to the
DKC3.1!
There are the following possibilities for free configuration/expansion:
•
The user can freely expand the length of cyclic data channel P-0-4082
or P-0-4071 up to a maximum of 9 words. Apart from the control and
status word, further real-time data can be configured via the
parameters
P-0-4080, Field bus: config. list of cyclic actual value
data ch.
and
P-0-4081, Field bus: config. list of cyclic command
value data ch.
.
•
The content of
S-0-0144, Signal status word
can be freely
parameterized via
S-0-0026, Configuration list signal status word
and
S-0-0328, Assign list signal status word
.
Freely Configurable Mode (Rexroth Profile Type)
Brief Description
To use the extensive and numerous functions of a Rexroth drive with field
bus interface it is necessary, in addition to the I/O mode (downwards
compatible to the DKC3.1), to define another profile, the freely
configurable mode. This implies the use of a new controls and status
word (
P-0-4077, Field bus: control word
and
P-0-4078, Field bus:
status word
).
•
The structure (content) of the real-time data channel must be defined
via the configuration parameters P-0-4080 and P-0-4081. No profile-
dependent settings and checks are carried out!
•
In this profile type the Rexroth-specific definitions for the field bus
control and status words apply. Some bits in the parameters
P-0-4077,
Field bus: control word
and
P-0-4078, Field bus: status word
can
only be used in conjunction with certain operating modes.
•
This profile type allows using the entire drive functionalities (e.g.
velocity synchronization, drive-controlled positioning, ...).
•
The primary and secondary modes of operation can be freely selected
via S-0-0032, S-0-0033, S-0-0034 and S-0-0035.
