2. Fasten with screws and no.4 standoffs L=26.5mm the SBI board to the regu-
lation board, see gure 3A. In case there is the SBI-OFM/OFS-32 card, fasten
the SBI card to the drive regulation card by means of screws and 2 standoffs
L=10 mm + 2 standoffs L=26.5mm, see gure 3B.
The BUS connector is turned in the same direction as the regulation board
terminals.
3. The at cable is connected between the XO connector placed on the R-TPD32-
EV card and SBI-DN card. In case there is the APC300 card, connect the at
cable from APC300 to XO connector on SBI-DN card.
4. The Baud Rate of the SBI board is set via the Switches 7 and 8 of the Dipswi-
tch S1. The Baud Rate is detected only when the board is switched on and it
can be modied only by switching off and swtching on the board again.Table
2 shows the relation between the DIP-Switches and the selectable Baud Rate
value. The Default value is 125 Kbaud.

5. The dip switch S1 determines the Slave address. The address “0” is reserved
to the Master and it must not be used. The switches S1 -7 and S1-8 do not
determine any address. The address is detected only when the board is swi-
tched on. If the address is modied, the Drive has to be switched off and then
switched on in order to assume the new address.
6. Connect the Bus cable to the BUS connection terminal.
7. Switch on the drive.
8. The LEDS PWR and RUN light up.
9. Switch the Device Net power supply on; the LED H1 lights up.

3.2 DATA TRANSFER VIA EXPLICIT MESSAGING
The data transfer via Explicit Messaging is made through two new objects: one for
accessing the Drive parameters, the other to access the parameters of the APC
option card.
3.2.1 Drive Parameter Access
For reading/writing the drive parameters the Drive Parameter Access object is
dened with the following characteristics:
- Class ID: 66h.
- Class Attribute: Revision
- Instance Attribute: This instance does not provide any attribute.

3.2.1.6 Behavior
This object is the interface between the DeviceNet network and all Drive parame-
ters. The access to the Drive parameter is carried out by the parameter index; if the
parameter does not exist or may not be accessed for any reason (for example: try
to write a read only parameter) an error code will be returned.
Drive parameters in text format cannot be accessed.
In the following are repeted patterns of how the data frame of data has to be com-
posed for reading/writing Drive parameters.
3.2.1.6.1 Write Drive Parameter
In this example the writing of a Drive parameter is shown; the cases of positive or
wrong writing are distinguished.
3.2.1.6.1.1 Write Drive Parameter Request
The data frame for writing a drive parameter is composed as follows:

1) Byte or Word depending on the type of allocation executed by the Master.
2) The number of bytes of the “Value”-eld depends on the length of the Drive
parameter; i.e.: if the Drive parameter type is “Integer” the length of VALUE is
2 bytes.
3.2.1.6.1.2 Write drive parameter - Reply OK
If the Drive parameter is written correctly, the response is:
