Mitsubishi Electric has
upgraded the FR-F700-EC
range of inverters with
network support for BACnet, the
most common data communications
protocol in building automation and
control networks. Introduced in 1987,
BACnet is today the backbone of the
vast majority of building services
networks, and support for the
protocol on the FR-F700-EC makes it
easy to integrate the drive into
building services automation systems
for the likes of heating, ventilation
and air-conditioning control.

Particularly well suited to driving
fans and pumps, the FR-F700-EC also
provides built-in PLC functionality,
with support for functions such as
‘square root’ that can be used to
enable flow control – for example in
air conditioning systems – via PID,
using just an additional pressure
sensor. This can significantly boost
energy savings by enabling the true
airflow to be managed rather than the
pressure.
