
Position control
This inverter provides position control that enables the control of up to eight points with a single
inverter unit.
With the standard pulse train input function, it realizes accurate position control based on the feed-
back of the pulse generator (PG) signal or the encoder’s phase-A/B signal.

PID control function
The inverter provides PID control that adjusts the feedback value to match the target value.
This is available to the process control such as temperature, pressure, flow rate.

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
convenient, for example, when designing a replacement.
• Broadcasting to up to five groups (Simultane-
ous broadcast)
: Broadcasting to up five inverter groups can be performed
by dividing those located within a single network connect-
ed 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
processing time.
• Co-inverter communication
: Mutual data exchange can be performed among inverters,
without presence of the master in Modbus communication.
Environmental Consideration
OMRON gives consideration to not only the functions inherent to the inverter, but also its service life
and energy ef
ficiency
.
This inverter
, as a standard, complies with the RoHS Directive and other international standards to re-
alize an environmental-friendly inverter.

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.

Side-by-side installation
This inverter can be installed side by side, which contributes to the reduction of the installation
space.
Depending on the model, the reduction of the carrier frequency and the derating of the rated cur-
rent are required. Refer to 2-1-2 Installation Environment on page 2-2 for details.
