A.3
Configure the PROFIBUS Link
To configure this information into the drive, the following parameters
need to be set:
Table A-1 Basic set-up
Parameter
Value
Meaning
P75.02
10
Set the node address to 10
P75.06 is set to warn until the link has been fully commissioned, at
which time it can be set to the desired state.
To configure the drive set P75.05 to a 1. This will be rewritten to a
zero when configuration has been completed. With the PROFIBUS
link disconnected, or if the PROFIBUS master has not yet been
configured to communicate with slave 10, LED H3 will change from
steady to either flashing (no traffic detected on the network), or off
(traffic detected on the network). At the same time the warning LED
on the keypad will illuminate. When the PROFIBUS-DP Master has
been correctly configured for slave 10, with the correct packet
length, the warning LED will extinguish.
Note:
Setting P75.04 to a 1 allows the PROFIBUS board to
be automatically configured as the drive powers up.
Baud rate:
There is no Baud rate selection as the Slave
automatically Baud selects to the rate of the Master,
however the valid values are shown in Section 2.1.1.
A.4
Adding Drive Parameters
Having configured the PROFIBUS link it is then necessary to
configure where the information to be transmitted over the link
comes from and received information goes to. There are three basic
types of data parameters: simple parameters, references and
control/status bits.
A.5 Simple
Parameters
Simple parameters are parameters that the PROFIBUS board can
write to or read from directly. In this example the minimum speed,
speed feedback and torque demand are examples of simple
parameters.
To transmit simple parameters out onto the link, enter the
parameter number into the appropriate Transmit parameter. The
set-up for monitored values would be as in Table A-2 below.
