10.2.4 Expansion card -SERCOS-
This chapter describes the SERCOS expansion card for SERVOSTAR 600.
Information on the range of functions and the software protocol can be found in the manual
"IDN Reference Guide SERCOS".
10.2.4.1 Front view
10.2.4.2 Light emitting diodes (LEDs)
RT
indicates whether SERCOS telegrams are being correctly received. In the final Communi
-
cation Phase 4 this LED should flicker, since cyclical telegrams are being received.
TT
indicates that SERCOS telegrams are being transmitted. In the final Communication
Phase 4 this LED should flicker, since cyclical telegrams are being transmitted.
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 communication,
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
DRIVE.EXE on the SERCOS screen page, by altering the parameter for the cable length.
10.2.4.3 Connection technology
For the fiber optic cable connection, only use SERCOS components to the SERCOS Standard IEC
61491.
Receive data
The fiber optic cable carrying receive data for the drive in the ring structure is connected to X13 with
an F-SMA connector.
Transmit data
Connect the fiber optic cable for the data output to X14 with an F-SMA connector.
