In drive configurations with an "electrical shaft", simple auxiliary drives
operating in angular synchronism or other devices which require an
actual position value of the machine are often needed in addition to the
main position-controlled drives. These auxiliary drives and devices
have a pulse encoder input and read in the data supplied by a pulse
encoder mounted centrally on the line shaft. On drives with an electrical
shaft and flexible configuration, this central point is often impossible to
physically define. The SIMOLINK Encoder (SLE) thus simulates an
encoder on the electrical shaft and supplies a central actual machine
value (actual position) which is generated from the master setpoint. The
electrical shaft with the position-controlled main drives is implemented
by means of SIMOLINK and MASTERDRIVES Motion Control drives.
Using an angle setpoint transported via SIMOLINK, the SIMOLINK
Encoder generates two pulse signals in quadrature and a zero pulse.
These are supplied to further devices via the RS422 (EIA422 standard).
It thus simulates a pulse encoder with selectable pulse number per
revolution (1024, 2048, 4096, 8192).
There are two models of SIMOLINK Encoder. The SLE module offers
SIMOLINK functionality and a built-on parameterization device. The
SLE-DP module (SIMOLINK Encoder with PROFIBUS-DP interface)
features the additional option of altering certain parameter settings
remotely via the PROFIBUS.
The SIMOLINK transmission medium is a fiber-optic cable. Fiber optics
made of glass or plastic may be used. SIMOLINK has a ring-shaped
structure, with each node in the ring acting as a signal amplifier. A
maximum of 201 active nodes can be interconnected on the SIMOLINK
ring.
