9.5.6 SIMOLINK
9-118
The SIMOLINK drive interface is the "backbone" of the synchronization
function. SIMOLINK distributes path/angle setpoints and velocity
setpoints from the master axis to the slave axes quickly and time-
synchronously. The synchronization of the sampling times of all stations
is assured by special SYNC messages.

The "Communication" chapter in this Compendium provides
detailed information on the configuration and commissioning of
SIMOLINK.
The list below provides a brief overview:
SIMOLINK has the following features:
♦ Fiber-optic ring with plastic or glass fiber
♦ Baud rate 11 Mbaud
♦ Max. 200 nodes per fiber-optic ring
♦ Polling time with 100 data messages each with 32 bits: 630 µsec
♦ Jitter-free synchronization of the sampling times of all stations by
special SYNC messages
♦ Peer-to-peer configuration (drive-to-drive interface without master)
or master/slave configuration possible
♦ Max. cable length:
• 40 m with plastic
• 300 m with glass
• 1000 m for complete ring
♦ Up to 1000 double word message frames can circulate on the
SIMOLINK ring.
♦ Binectors and connectors allow flexible wiring of signals from and to
the SIMOLINK per software in MASTERDRIVES MC [150...160].
Applications of SIMOLINK:
♦ Replacement of mechanically coupled moving axes with individual
drives
♦ Transmission of angle setpoints between master and slave axes for
angular synchronization and cam function
♦ Replacement of conventional RS485 peer-to-peer connection for
data exchange between SIMOVERT power converters
