SIMOLINK Pulse Generator 02.2001 Product Description
2 Product Description
In drive configurations with an "electrical shaft", simple speedsynchronized 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.
NOTE
For further information about SIMOLINK, please refer to Chapter
"Communication / SIMOLINK“ of the SIMOVERT MASTERDRIVES

SIMOVERT MASTERDRIVES Operating Instructions 2-1
Product Description 02.2001 SIMOLINK Pulse Generator
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 deadtime 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.

How to assemble a
bus cable
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.

The SIMOLINK Pulse Generator updates the setpoint output in
response to every SYNC interrupt with which error-free data are
received. If a communications error occurs, the generator continues to
operate on the old setpoint. If CRC errors occur 8 times in succession,
it sets the frequency generator directly to 0 Hz and does not restart it
until an error-free setpoint is received. It switches to 0 Hz immediately if
communication on the SIMOLIN K is abort ed.
The frequency output of the SIMOLINK pulse generator in the 90°
pulses mode is identical to that of a pulse generator with 1000
pulses/rev and a speed normalization of 1 00 % = 1500 rev/min. If the
generator is to simulate shaft encoders with other pulse numbers per
revolution or different speed normalization, the setpoint to the SLP must
be renormalized. This can be done, for example, by multiplying the
machine setpoint. In this regard, it is important to note that the
maximum setpoint for the SLP on the SIMOLINK data interface must
not exceed 112 % (max. output frequency of approximately 28 kHz in
90° pulse mode).

Fig. 6-4 Example of setpoint normalization parameter settings
The processing time slot and sequence must be taken into account in
the parameter settings. If a time slot other than the time slot for setpoint
calculation is used or the processing sequence altered, the resulting
dead times will cause a lag in the signal output when the setpoint is
changed.
