Components which can be destroyed by electrostatic discharge (ESD)

The board contains components which can be destroyed by

electrostatic discharge. These components can be easily destroyed if

not carefully handled. If you have to handle electronic boards, please

observe the following:

Electronic boards should only be touched when absolutely necessary.

The human body must be electrically discharged before touching an

electronic board.

Boards must not come into contact with highly insulating materials - e.g.

plastic parts, insulated desktops, articles of clothing manufactured from

man-made fibers.

Boards must only be placed on conductive surfaces.

Boards and components should only be stored and transported in

conductive packaging (e.g. metalized plastic boxes or metal

containers).

If the packing material is not conductive, the boards must be wrapped

with a conductive packaging material, e.g. conductive foam rubber or

household aluminum foil.

The necessary ESD protective measures are clearly shown again in the

following diagram:

SIMOLINK Pulse Generator 02.2001 Product Description

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.

For further information about SIMOLINK, please refer to Chapter

"Communication / SIMOLINK“ of the SIMOVERT MASTERDRIVES

Compendium Motion Control, Order No.: 6SE7087-6QX50.

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.
