12 Serial interfaces
The frequency controllers
tan
communicate with superimposed
hosts (PLC and PC) and the Lenze operating units 323 and 324 via
the serial interfaces
LECOMl
and LECOM2.
12.1
LECOMI
interface X6
The
LECOMl
interface (X6 connector)
tan
be used to connect
devices to the
RS232C
Standard
(LECOM-A) or to the RS485
Standard
(LECOM-B). The interface is suitable for Parameter
setting, monitoring, diagnosis, and simple controls.
Using the
very
common
RS232C
interface, simple
point-to-point-
connections with a cable length of a maximum of
15m
are possible.
Almost every PC or other hosts
have
this interface.
Using the
RS485
interface,
several
controllers
tan
be connected to
a superimposed host (multi-point connection). If you use the
2101 IP interface, cable lengths up to
1200m
are possible.
The LECOM-NB protocol is based on the ISO
Standard
1745 and
supports up to 90
drives.
lt recognizes faults and therefore avoids
the transmission of incorrect data.
