SERCOS INTERFACE SETUP
The SERVOSTAR S- and SERVOSTAR C-Series drives comes with SERCOS
interface communication capability. It must be ordered from the factory with
this option. The Encoder Equivalent Output D9 connector (C4) is replaced with
two fiber-optic ports, transmitter (Tx) and receiver (Rx).
This section provides the SERCOS interface-specific information needed to
complete the installation and setup of a SERCOS interface SERVOSTAR drive
to the fiber-optic ring.
DIP Switch Configuration
DIP switch configuration is similar to that of the standard SERVOSTAR drive.
Through these switches, the drive’s address and communication power levels
are set.
Setting Drive Address
Up to 31 SERVOSTAR drives can be configured on the SERCOS interface
ring. The first five switches of the DIP set the drive address.
When the address is
zero (00000), the drive operates as a SERCOS interface repeater and as a single-
axis unit with serial communication. You can monitor and configure the drive
through the serial port. Any other address setting, 1-31 (00001 – 11111),
establishes the drive as an active SERCOS interface ring participant with
communications through the Tx/Rx ports. When the drive has a non-zero
address, you can communicate through the serial port only for monitoring
purposes.
Setting Transmission Power Levels
The SERCOS interface transmitter power level (DIP switch 9) should be set
according to the expected signal attenuation between a SERCOS interface
transmitter and the next receiver. Signal attenuation is based upon cable length,
cable type, and intermediate connection losses (e.g. bulk head connectors). The
following table may be used to calculate the maximum allowable and minimum
required signal attenuation for a given power level and cable attenuation:
Power Level Attenuation Specifications
Attenuation Low Power High Power
Maximum 9.5 dBm. + 2 m. *Ac 12.5 dBm. + 2 m. *Ac
Minimum - 1.5 dBm. + 2 m. *Ac
Note: Ac = Fiber optic cable attenuation in dBm./m.
