Installing the expansion card
To fit the sercos
®
II expansion card, proceed as follows:
1. Remove the cover of the option slot (see instructions manual of the servo amplifier.)
2. Take care that no small items (such as screws) fall into the open option slot.
3. Push the expansion cardcarefully into the guide rails that are provided, without
twisting it.
4. Press the expansion card firmly into the slot, until the front cover touches the fixing
lugs. This ensures that the connectors make good contact.
5. Screw the screws on the front cover into the threads in the fixing lugs.

LEDs
RT
Indicates whether sercos
®
telegrams are being correctly received. In the final
Communication Phase 4 this LED should flicker, since cyclical telegrams are
being received.
TT
Indicates that sercos
®
telegrams are being transmitted. In the final Communica-
tion Phase 4 this LED should flicker, since cyclical telegrams are being transmit-
ted.
Check the stations addresses for the controls and the servo amplifier if:
- the LED never lights up in sercos
®
Phase 1 or
- the axis cannot be operated, although the RT LED is lighting up cyclically.
Err
Indicates that sercos
®
communication is faulty or suffering from interference.
If this LED is very bright, then communication is suffering strong interference, or
is non-existent. Check the sercos
®
transmission speed for the controls and the
servo amplifier (BAUDRATE) and the fibre-optic connection.
If this LED flickers, this indicates a low level of interference for sercos
®
commu-
nication, or the optical transmitting power is not correctly adjusted to suit the
length of cable.
Check the transmitting power of the (physically) previous sercos
®
station. The
transmitting power of the servo amplifier can be adjusted in the setup software
on the SERCOS screen page, by altering the parameter for the cable length.
2.1.4
Connection technology
For the fiber optic cable (FOC) connection, only use sercos
®
components to the sercos
®
Standard IEC 61491.
Receive data
:
The fiber optic cable carrying receive data for the amplifier in the ring
structure is connected to
X13
with a F-SMA connector.
Transmit data
:
Connect the fiber optic cable for the data output to
X14
with a F-SMA
connector.
Tightening torque for connectors max. 0.8 Nm.
