Introduction to ACS320
AC drives for pump and fan applications
ACS320 - XXU - XXXX - 2 + XXXX
Making HVAC user friendly
The preprogrammed application macros and easy to use control
panel make installation and drive setup simple. The control
panel on the ACS320 uses HVAC terms and units, removing any
guess work, and comes with 18 languages built-in. The unified
height and depth of the drive frame sizes minimizes needed
installation space.
Energy savings
With energy savings of up to 70 percent, the ACS320 can help
to attain sustainability targets. The drive’s energy optimizer
tunes the drive’s performance to help save even more energy.
Built-in energy efficiency calculators monitor the energy used
and saved. The savings are shown in kilowatt-hours and in local
currency. Carbon dioxide (CO2) emission reductions are also
shown.
Complete HVAC functionality
The ACS320 comes standard with four embedded
communication protocols, including BACnet (MS/TP) for easy
integration into building management systems. Built-in real
time clock and timers help you optimize energy use. The drive
provides full output current at ambient temperatures of up to
50°C without derating. Built-in software for controlling common
HVAC applications includes:
− 2 PID controllers
− Timers with real time clock
− Pump and fan control
− Cooling fan control
− Pump cleaning
− Underload (broken belt) detection
− Pump protection
− Sleep function
− Pipe fill (precharge)
Typical applications for the ACS320 include:
− Supply and return fans
− Condenser fans
− Exhaust fans
− Fume hood fans
− Booster pumps
− Submersible pumps

Typical applications
The ACS320 drive is specically designed to meet the variable
torque loads demanded by centrifugal fans and pumps. The
result is maximum application uptime, reduced maintenance cost
and higher energy savings.
A booster pump system is designed to boost supplied water
pressure to a predetermined level in commercial buildings. The
ACS320 drive features pump and fan control (PFC) for use where
several parallel pumps are operated together and the required
flow rate is variable.
PID control is available to allow the process to accurately
maintain a pressure setpoint by adjusting the control outputs,
thus allowing for precise control within difficult processes.
A sleep & boost function detects slow rotation and runs the
pump to boost pressure prior to shutdown. The pressure
is continuously monitored and pumping restarts when the
pressure falls below the minimum level.
Fan arrays use multiple motors that are often controlled by
individual drives. The ACS320 offers exibility in mounting with
its compact footprint. Multiple drives in this arrangement provide
redundancy ensuring year round comfort. With the optional UL
type 1 kit installed on ACS320 drives the drive is plenum rated
and suitable for use in the air stream. Built in building automation
protocols that come standard with the product allow the user to
easily set up and run the drive using BACnet, FLN, N2 or Modbus
RTU reducing commission time.
Supply and return fans need to maintain air quality in spaces
throughout commercial buildings, schools and hospitals. The
ACS320 provides a selection of single phase 230V, three phase
230V and three phase 480V drives rated up to 30 Hp in a
compact, exible design. Whether it is cold winter nights or hot
summer days, the rugged design can handle the environmental
extremes with a -10 to 50 °C (14 to 122 °F) ambient temperature
rating, while keeping occupants comfortable.
