Expansion card -SERCOS-

This section describes the SERCOS expansion card for SERVOSTAR 300. Information
on the range of functions and the software protocol can be found in our manual "IDN
Reference Guide SERCOS".
If you ordered the expansion card together with the servo amplifier, then the expansion
card is already fitted and screwed into the slot when the servo amplifier is delivered.

Connection technology

For the optical fiber (LWL) connection, only use SERCOS components to the SERCOS
Standard IEC 61491.
Receive data
The optical fiber carrying receive data for the drive in the ring structure is connected to
X13 with an FSMA connector.
Transmit data
Connect the optical fiber for the data output to X14 by FSMA connector.

Indicates whether SERCOS telegrams are being correctly received. In the final
Communication Phase 4 this LED should flicker, since cyclical telegrams are being
received.
Indicates that SERCOS telegrams are being transmitted. In the final Communicati-
on Phase 4 this LED should flicker, since cyclical telegrams are being transmitted.
Check the station 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.
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 ser-
vo amplifier (BAUD RATE) and the fiber-optic connection.
If this LED fades or flickers, this indicates a low level of interference for Sercos
communication, or the optical transmitting power is not correctly matched to the
length of cable. Check the transmitting power of the (physically) previous SER-
COS station. The transmitting power of the servo amplifier can be adjusted in the
setup software DRIVEGUI.EXE on the SERCOS screen page, by altering the LWL
length parameter for the cable length.
