SIMOLINK Pulse Generator 02.2001 Product Description
Siemens AG GWE-477 764 4070.76 J
SIMOVERT MASTERDRIVES Operating Instructions 2-1
2 Product Description
In drive configurations with an "electrical shaft", simple speed-
synchronized auxiliary drives or other devices which require an actual
machine value proportional to velocity are frequently 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 Pulse Generator (SLP)
thus simulates an encoder on the electrical shaft and supplies a central
actual machine value (machine velocity) 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.
The SIMOLINK Pulse Generator uses a speed setpoint transported via
SIMOLINK to generate two pulse signals in quadrature of proportional
frequency (100 % = 25 kHz). These are supplied to further devices via
the RS422 (EIA422 standard). The frequency output corresponds to
that of a pulse encoder with 1000 pulses/rev and a speed normalization
of 100 % = 1500 rev/min.
A "100 kHz operating mode" can be activated optionally. Instead of the
signals in quadrature, one signal supplies the quadruple frequency
proportional to the setpoint (100 % = 100 kHz) and the other signal
supplies the sign.
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.

"Communication / SIMOLINK“ of the SIMOVERT MASTERDRIVES
Compendium Motion Control, Order No.: 6SE7087-6QX50.

Product Description 02.2001 SIMOLINK Pulse Generator
GWE-477 764 4070.76 J Siemens AG
2-2 Operating Instructions SIMOVERT MASTERDRIVES
2.1 Description of function
The incoming optical signals from the fiber-optic cable are converted to
electrical signals by means of fiber optic receivers on all SIMOLINK
modules and then transferred to the fiber-optic transmitter where they
are converted back to optical signals. The propagation delays caused
by this process are calculated while SIMOLINK is booting and the dead
times compensated accordingly for active SIMOLINK nodes. The
receive information is derived, depending on parameterization, from the
buffered, electrical signals and transferred with the SYNC interrupt (last
telegram in SIMOLINK polling). The transmit information of the node is
transferred in the opposite direction and written to the associated
telegrams (electrical signals).
The SIMOLINK Pulse Generator is incorporated in the SIMOLINK ring
like a SIMOLINK slave; it is an active node and included in the dead-
time calculation. However, it does not have its own node address and
cannot therefore write transmit telegrams to the SIMOLINK (SLP does
not supply a return value).
The SIMOLINK receive address (0 ... 200; dispatcher mode: Address of
node which is sending the speed setpoint) is set via the DIL switches
on the front panel. The momentary speed setpoint is read in the
MASTERDRIVES 32-bit format (4000 0000 hex = 100 %) from channel
0. Only the 10 highest bits are resolved with a maximum output of
112 %, resulting in a speed resolution of 0.4 %. The speed setpoint
must be updated (new setpoint or identical value if velocity is constant)
in every SIMOLINK cycle by the transmitting node.
The speed setpoint is transferred to the frequency generator with the
SYNC interrupt which then generates the equivalent frequency with the
correct phase sequence of the two output signals (tracks A and B). An
output frequency of 25 kHz corresponds to a speed setpoint of 100 %.
Alternatively, a jumper can be inserted in the mating connector of X2 to
activate the "100 kHz signal" operating mode. The frequency generator
can then output signals from 0 to 100 kHz. In this mode, the frequency
signal is output via track A and the sign (direction of rotation) via track
B. The sign is a static 0 (positive) or 1 (negative) signal.
The RS422 interface forms the desired signal levels which can be
picked off on SUB D socket X2.
The operating states are indicated by the three LEDs on the housing
front panel.

5.3 Fiber-optic cable connection
The fiber-optic cables are connected via plug-and-socket connectors.
The transmit and receive sockets are on the bottom of the housing (Fig.
4-2). The output power of the fiber-optic transmitter is not variable, but
permanently set to the maximum transmitter power defined for
SIMOLINK.
SIMOLINK is a clocked, ring-shaped
fiber-optic bus system. To allow the
flow of signal traffic, the transmit
socket of the first node must be
connected to the receive socket of
the next node and so on, until the
transmit socket of the last node is
connected to the receive socket of
the first node.
The receive socket is dark grey and
labeled RX. The transmit socket is
light gray and labeled TX.
The following Hewlett Packard fiber-
optic modules are installed in the
SIMOLINK Pulse Generator:
♦Transmitter: HFBR 1528
♦Receiver: HFBR 2528
Plastic or glass fiber-optic cables can be used. Depending on the type
of cable selected, the inter-node distances are as follows:
♦Max. 40 m between each node in the case of plastic cables or
♦Max. 300 m between each node in the case of glass cables.
The maximum permissible ring bus length is 1000 m.
A components package for assembling plastic fiber-optic cable
connections can be ordered under number 6SX7010-0FJ50. This
contains: 100 m plastic fiber-optic cable, 40 fiber-optic connectors, 20
connectors for terminal strip X470 SLB.
If glass fiber optics are the selected medium, the connectors attached
to the fiber-optic cable must be suitable, i.e. they must fit into the
transmit and receive sockets on the SIMOLINK Pulse Generator.

5-6 Operating Instructions SIMOVERT MASTERDRIVES
To make connections on a plastic fiber-optic cable, please follow the
instructions below:
1. Cut the correct length of fiber-optic cable. Make sure you cut the
cable at right angles, use a sharp knife. (Fig. 5-7 )
2. Remove approximately 7 mm of the outer, black sheath on the cable
using a suitable cable stripping device. Take great care not to
damage the fiber optic when removing the sheath!
3. Insert the fiber-optic cable into the connector (Fig. 5-7 ó) and push
it into the cylindrical sleeve as far as it will go. The transparent fiber
optic will protrude out of the other side of the sleeve.
4. Fold round the gripping half of the connector and close it by hand
(Fig. 5-7 ì). Once the top half of the connector is latched into the
lower half, the cable is lodged securely in the connector.
5. Use a sharp knife to cut the protruding end of the cable almost flush
with the connector surface. Cut at right angles to the fiber-optic
cable axis.
6. You now need to polish the surface of the fiber optic. To do this,
place the end of the sleeve flat on the surface of the matt, rough
side of the green polishing paper supplied, and "draw" a figure of 8.
Then clean the end with a clean, lint-free cloth.
7. The sleeve end can be polished finely to reduce throughput losses
to a minimum. Fine polishing reduces throughput losses by
approximately 2 dB. To fine polish the sleeve, place it vertically on
the matt, rough side of the pink polishing paper and "draw" a figure
of 8 about 25 times. Then clean the end again with a clean, lint-free
cloth.
