This inverter is designed as standard to provide connectivity to open field networks. In addition to
built-in Modbus communication functions, the inverter also supports various system designs.
⚫
Open field network
Installing any of the following optional communications units enables the inverter to support the cor-
responding open network.
It means that the host of each communications unit can perform the inverter operations, stop con-
trol, status monitor, and functions to read and write various parameter settings.

⚫
Modbus communication functions
This inverter has built-in Modbus communication functions as standard.
These Modbus communication functions of the inverter include sophisticated, convenient functions
as listed below.
•
Modbus mapping : Up to 10 register addresses can be set as desired. This is con-
venient, for example, when designing a replacement.
•
Broadcasting to up to 5 groups
(Simultaneous broadcast) : Broadcasting to up five inverter groups can be performed by
dividing those located within a single network connected to
this inverter. It is useful to reduce the variation in the startup
timings within a group.
•
High transmission speed : This inverter supports the maximum transmission speed of
115.2 kbps. This helps reduce the communications data pro-
cessing time.
•
Co-inverter communication : Mutual data exchange can be performed among inverters,
without presence of the master in Modbus communication.
OMRON gives consideration to not only the functions inherent to the inverter, but also its service life
and energy efficiency.
⚫
Automatic energy-saving function
The automatic energy-saving function automatically adjusts the output power of the inverter operat-
ing at a constant speed to the minimum. It has an energy-saving effect in applications such as a fan
or pump.
⚫
Compliance with safety standards
All models of the inverter comply as standard with the EC Directive and UL/cUL Standards.
⚫
Complies with RoHS Directive
The Inverter also complies as standard with the RoHS Directive, which restricts the use of hazard-
ous substances.
