10 Serial interfaces
The frequency inverters can communicate with superimposed hosts
(PLC and PC) and the Lenze operating units 323 and 324 via the
serial interfaces LECOM1 and LECOM2.
10.1 LECOM1 interface X6
The LECOM1 interface (X6 connector) can 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 can be connected to
a superimposed host (multi-point connection). If you use the 2101IP
interface, cable lengths up to 1200m are possible.
The LECOM-A/B protocol is based on the ISO standard 1745 and
supports up to 90 drives. It recognizes faults and therefore avoids
the transmission of incorrect data.
