Profibus-DP is a high
speed communications network
and protocol, that allows
large amounts of data to
be transferred quickly to
and from
network are "centralised"
systems, requiring a master
controller (such as a PLC)
which controls the communications
with the slave nodes on
the network. The Profibus-DP
interface for Unidrive is
a slave node only. |

| Key
Features |
|
|
| - |
Supplied
as the large
option module
and fits easily
under the Unidrive
Keypad |
| - |
Full
co-processor
functionality
is retained |
| - |
Supports
data rates up
to 1.5 Mbits/sec |
| - |
Automatically
recognises the
network data
rate |
|
|
|
|
 |
|
| - |
Supports three 16
bit cyclic data channels |
| - |
Two cyclic data
channels can be combined to produce
a single 32 bit cyclic data channel,
allowingcomplete access to all
co-processor Position Controller
parameters via the Profibus-DP
network |
| - |
Full cyclic data
channel mapping allows any cyclic
data channel to control or source
from any driveand
co-processor parameters |
| - |
Default mappings
* Speed/frequency feedback
* Torque feedback
* Status word provides status
bits about 15 drive functions,
eg drive healthy, drive running,
at speed, etc
* Speed/frequency reference
* Torque feedback reference
* Control word allows ENABLE,
RUN, and DIRECTION signals, plus
reference selection and user bit
parameters to be transmitted in
one cyclic data word |
| - |
Non-cyclic data
channel allows the master controller
to access any drive parameter |
| - |
Network loss detection
will trip the drive (if enabled),
when network connection is lost |
| - |
Local network diagnostics |
| - |
Endian selectable |
|
