2.1.2 Inserting the expansion card (AX2000)
To fit the PROFIBUS expansion card into an AX2000, proceed as follows:
l Remove the cover of the option slot (see installation manual of the servo amplifier.)
l Take care that no small items (such as screws) fall into the open option slot.
l Push the expansion card carefully into the guide rails that are provided, without twi-
sting it.
l Press the expansion card firmly into the slot, until the front cover touches the fixing
lugs. This ensures that the connectors make good contact.
l Use the screws on the expansion card to secure it in the drive.

2.1.2.2 Setup of Station Address and Baud Rate
During setup it makes sense to use the keypad on the front panel to preset the station addresses
for the individual amplifiers (see chapter "Setup" in the installation manual).
After changing the station address you must turn the 24V auxiliary supply for the servo
amplifier off and on again for the new address to take affect.
Possible ways for setup:
l keypad on the front panel of the servo amplifier (see installation manual)
l setup software: screen page “CAN / Fieldbus”
l serial interface with a sequence of ASCII commands:
ADDR nn Þ SAVE Þ COLDSTART (with nn = address)
The Baudrate is defined by the hardware configuration in the master controller. Baudrates up to 12
MBaud are possible. During bus initialization, the master controller sends the amplifier the desired
baud rate.
2.1.2.3 Connection technology
Cable selection, cable routing, shielding, bus connector, bus termination and transmission times are
all described in the “Installation guidelines for PROFIBUS-DP/” from PNO, the PROFIBUS User
Organization.
