5.
The 9200 servo axis modules can communicate via the serial
interfaces LECOM1 and LECOM2 with superimposed hosts (PLC
or PC) as well as Lenze operating units.
The LECOM1 interface (connector X1) is used to process the
LECOM A/B protocol. The LECOM1 interface can also be used to
connect devices to the RS 232C standard (LECOM-A) or to the RS
485 standard (LECOM-B). The interface is suitable for parameter
setting, monitoring, diagnosis and process control.
For more demanding applications, a field bus connecting module
can be used. For the parameter setting, this interface is generally
called LECOM2.
The following bus systems are available:
• Interbus-S interface module 2110
• Profibus interface module 2130
5.1.
The standard serial interface X1 fulfills the standard RS 232 C as
well as the standard RS 485.
Using the common RS 232 C interface, simple point-to-point
connection with a maximum cable length of 15 m can be achieved.
Almost every personal computer (PC) or other master system is
equiped with this interface. For several drives and larger distances,
the RS 485 interface must be used. Only two wires are used to
enable the communication of up to 31 controllers via a maximum
distance 1200 m.
The LECOM A/B protocol is based on the 1745 ISO standard and
supports up to 90 controllers. It recognizes faults and therefore
avoids the transmission of faulty data.
