• non-qualitied personnel is prohibited trom working at the
equipment and machinery or in its vicinity.
Oualitied personnel inoludes persons who, based on their training,
experience and instructions as weil as their knowledge ot the
relevant standards, regulations, satety standards and operational
environment, have been authorized by the person responsible tor
the safety ot the equipment to pertorm the required work and are
able to recognize and avoid potential risks.
(Definition ot qualitied personnel according to VDE 105 or tEC

1. Survey
LECOM-LI is a grnup et cennectinn elements te centrel the Lenze
drive centrellers via plaatic tibre-optic cablea.
The greup et LECOM-LI cnnnectien elements cemprises adaptnrs
with optical tranamitters and nptical receivers, diatributers and
pewer supply unit tor intercennecting plastic fibre-eptic cables.
As drive centrnller yen mey use any unit of the follewing series
equipped with the RS-232 interface:
• 4800
• 4900
• 8100
• 8300
• 8600
• 9200
Any computer equipped with the RS-232 interface can be uaed as
master:
• PLC
• PC
• treely pregrammable procesaer
The tibre-eptic adapter must be directly cennected te the RS-232
interface ef the Lenze drive controtler and the master computer.
All the single drives are interconnected in a ring-type netwerk by
means ot an tibre-eptic cable which starta and ends at the master.
The drive controliers are optically, not electrically interconnected.
As a result the communication cables have the best posaible
protection againat electrical interterences (EMC>.

2. General
2.1 Function
LECOM-LI werks on the basis of optical transmission by means ot
plastic tibre-optic cables.
The tibre-optic adaptors are equipped with an optical tranamitter
and an optical receiver.
By meaes ot the electrooptic tranaducer (light tranamitter) electrical
signals are changed to optical signals, the optoelectric transducer
changes (light receiver) optical signals te electrical signals.
The fibre-optic adaptor is equipped with two Iamps tortunction
control:
The receivlflg pilot lamp (RxD) flashes when receiving an
optical signal.
Thetransmitting pilot lamp (TxD) tlashes when
transmitting an optical signal
The tibre-optic adaptor must be directly connected te the RS-232
interface of the digitized Lenze drive controllerorthe master
computer.

2.2. Cammunlcatian protacol
LECOM-LI supports the communication protocol
— LECOM-A/B.
The protocol LECOM-A/B allows the master computer te use all
parameters of the drive controller. LECOM-A/B transmits all
parameter values in (orm ot acknowledged messages.
The transmission time is 9600 baud which means 20 te 30
parametern are transmitted per second. The transmission ot one
parameter usually takes abeut 30 ms te max. 50 ms.

2.3 Type af cannectian
LECOM-LI is the optical connection between the master computer
and the drive controller.
2.3.1 Fibre-aptic ring
A ring.shaped topology is used. The signals are transmitted to the
next ring by means 01 an tibre-optic adaptor. The optical signal is
amplitied by the fibre-optic adaptor and transmitted te the next
component ot the ring. The TxD-lamp at Ihe tibre-optic adaptor
flashes when an optical signal is amplified and transmitted and a
signal is transmilted by the controller.
