Facility Managers Say...
► “As the U.S. HVAC Market Leader
and the world’s largest manufacturer
of Adjustable Frequency Drives, I
know that ABB will be here in 10
years time and beyond. This is the
most important guarantee you can
give me.”
► “With ABB’s standard built-in
hardware like the 5% swinging
choke and the EMI / RFI lter, I
know that any sensitive equipment
in my facility will not be adversely
affected by drive operaton.”
► “I love the Help button. I call it
my panic button – it quite simply
is always available to guide me with
useful information.”
► “The Maintenance Assistant is
another great feature of the ABB
Drive. I simply do not need to worry
about when it is time to service the
equipment. The drive tells me when
it is time to send people to perform
maintenance.”
Peace of Mind
Wide power range
from 1 to 100 Hp, @ 208/240 V or 2 to
500 Hp @ 380/480 V, covering the vast
ma jor i ty of HVAC applications.
Built-in EMI/RFI lters
The ACH Series Drive meets
the EMC product standard
EN61800-3 for the 1st Environment. These lters eliminate the
need for any additional external
ltering hardware.
Built-in timers
External timer circuits are
no longer needed. Built-in
timers - utilizing the realtime clock - allow starting
and stopping the drive or
changing the speed according to the time of day
or night. Relay outputs can
be operated with timers to
control any auxiliary equipment on site.

N2, FLN and Modbus
embedded
Commonly used HVAC eldbuses are embedded into the
memory of the drive, ensuring
that they are always there if you
need them. ABB has a long history in building automation, with
more than 400,000 installed
drives utilizing serial communications.
LonWorks and Pro bus
LonWorks, Pro bus and other plug-in
modules t under the cover of the drive. A
single twisted pair avoids great lengths of
conventional cabling, reducing cost and
increasing system reliability.

Swinging reactor - up to 64% less
harmonics
ABB's patent-pending swinging choke means
the ACH Series Drive reduces harmonics by
up to 64% at partial loads when compared
to a PWM AFD with no chokes. There is no
need to oversize the supply choke.
Pre-con gured HVAC
application macros
14 different HVAC application
macros are pre-programmed
into the HVAC drive. Application macros for supply and
return fans, cooling tower fans,
booster pumps and condensers are available, just to name
a few. The user can create two
additional application macros,
selectable manually or through a
digital input. To illustrate this, the
user can create "summer" and
"winter" application macros and
select between these according
to the time of the year.
A Contractor’s Point of
View...
► “With the Hand Macro, I can move air to
dry out the new construction paint and
drywall mud without calling for a certi ed
start-up. There’s no need for multiple
trips to my job site by the ABB start-up
Engineer to commission the drives, and
that saves me money.”
UL Type 12
The motor can deliver full
output at 40 °C - shouldn’t the
AFD do the same?
ABB's HVAC drive is rated for continuous operation to 40 °C with full
current, without being compromised
by temperature variations within any
24-hour period. Full circulation is
available, precisely when needed
- usually, when it is hot outside.
Similarly, Type 12 units can be
operated without the need for derating up to 40°C. And, at 50°C, only
10% de-rating is required for both
UL Type 1 and UL Type 12.
► “UL Type 12 enclosures keep the drive
electronics free from drywall dust and debris during the construction process.”
► “ABB ACH Series Drive enclosures are
UL Listed and UL Plenum Rated. I can
mount the drive in most locations without
worries.”
► “I don’t have to search for external com-
ponents like timers and PID contollers
and then worry about their compatibility.
It’s all there, in the drive”

Feedback From Temperature Control Contractors...
► “ABB understands the HVAC Mar-
ket. I save time and money because
I do not need to supply interposing
relays and control logic to accomplish ‘real world’ functions such as
Fireman’s override and damper endswitch proof. ABB has these and
many more features built-in.”
► “Finally, a BACnet-compatible
HVAC drive without the need for
expensive and unwieldy third-party
gateways.”
► “The ABB ACH Series Drive is actu-
ally a drive and unitary controller in
one. I have 13 free I/O points with
every ABB drive provided!”
Peace of Mind
Interactive maintenance assistant
Maintenance scheduling no longer requires guesswork. The HVAC drive alerts
you when maintenance is required based
on your individual requirements.
Fault logger
The fault logger of the
HVAC drive is especially useful in tracking down drive trips
through its use of the
real-time clock.
In addition to recording
both time and date,
the fault logger also
takes a snapshot of 7
diagnostic values - like
motor speed and output current. You know
what happened and
when.
—
► “The second PID loop built into
the ABB HVAC Drive allows me to
control cooling tower bypass valves
or other control valves with no additional hardware or cost.”
► “The ABB HVAC Drive is a temper-
ature controls engineer’s dream…
on-board passthrough I/O, a free
PID loop controller, and broken belt
indication. Damper end-switch and
smoke purge controls are built-in at
no additional charge!”
Two PID controllers as standard
The HVAC drive has two independent PID controllers built in. As an example: one PID controller works
with the AFD to maintain the duct static pressure;
simultaneously, the other PID controller can be used
to control a separate external device, e.g. a chilled
water valve. All of this can, of course, be monitored
and controlled through serial com mu ni ca tions.

Specifying Engineers State...
► “The 5% swinging choke means I do not
need to oversize my supply transformer
and cables to meet NEC 430-2.”
Interactive diagnostic assistant
Should a fault occur, the diagnostic
assistant displays, in plain language,
possible causes and potential solutions.
Flux optimization
This standard feature means the
drive supplies only the voltage
and current necessary to drive
the load. This results in reduced
energy consumption and much
lower motor noise levels. Silent
operation mode further reduces
motor audible noise for sensitive
applications.
► “Specifying a drive that meets EMC prod-
uct standards for the First Environment
means I will not have job site EMI / RFI
issues or complaints.”
► “A keypad that functions like a cell phone
– what could be easier?”
► “The built-in communications suite
means I can have intelligent drive applications regardless of which temperature
control contactor is successful on the project”
► “When I call ABB, I know I get the right
answer.”
► “ABB supplies submittal packages that
provide the detailed information and
drawings I need to verify quickly that
the ABB drive meets my speci cation
requirements. That information saves me
a lot of time.”
Versatile software tools
DriveWindow Light 2 further
facilitates commissioning and
maintenance. Pump & Fan
Save helps calculate energy
sav ings and pay-back times.
ABB’s Harmonics Calculator
allows the engineer to run
harmonics contribution estimates.

Unitary Controller - Built-In
1) The BMS commands start/stop; internal/external
PID setpoints; command digital (relay) outputs, and
analog (4-20mA) outputs and reset faults. The BMS
reads drive outputs; controlled variable feedback;
Hand/Auto selected indication; kWhrs (R); Operating hrs (R); drive amps (broken belt indication); drive
temperature; all warnings, faults, and much more.
2) Receive and monitor hard-wired devices -- restat/
freezestat safety contacts, smoke purge commands
-- over the serial link.
3) Open an isolation damper, override a VAV box or any
device that requires a maintained contact closure for
control. Receive damper end-switch proof contact.
4) The Keypad Display indicates feedback and setpoint
in inches of water column - or programmable units
intuitive to the user.
5) BMS commands a drive analog output to control hot
water valves or any device requiring a 4-20mA analog
input.
6) The drive’s external PID Loop Controller controls a
chilled water valve or any device requiring a 0-20mA
input. Feedback signal is hard-wired to AFD and setpoint is sent via serial comms.
7) Use the drive’s process PID Loop Controller to
maintain supply fan pressure via adjusting fan speed.
Pressure feedback is hard-wired to AFD and setpoint
is sent via serial comms.

Keypad & Firmware Features
The new ABB ACH Series Drive Keypad
takes the typical operator interface to a
new level.
ABB ACH Series Drive Keypads use full
language, no codes. And this keypad
emulates the human interface of a cell
phone. Easy as a mobile phone, and you
control a panel with intuitive handling in
14 languages.
The new ABB ACH Series Drive has pioneered several new-to-the-market features
such as Maintenance Assistants, Diagnostic Assistants, Programming Assistants,
and Help Screens.
For example, if there’s a trip off line,
pressing the Help Key brings the user
to the Diagnostic Assistant; it suggests
possible causes of the trip and probable
corrective actions.
Programming Assistants congure the
drive for an application. For example, the
PID Assistant prompts the user through
a series of 12 questions; and uses the answers to these questions to set 26 parameters inside of the drive’s program. No
need to navigate the drive menus!
The Maintenance Assistant alerts users
when equipment maintenance is required,
based on selected inputs. Utilize the
Revolution Counter and Maintenance As-
sistant to signal personnel when it’s time
to replace the pump packing.
The Keypad features two soft keys; their
functions change according to the operating state of the panel. Hand-Off-Auto
buttons provide local control for localspeed and start/stop control.
The Help Button brings up a description
of what the effect of parameter changes
would be – in full sentences!
Faults can be time and date stamped via
the real-time clock. A fault logger stores
status information such as amps, volts and
presence of a run command at the time
of the fault.
Patent-Pending Swinging Choke (Reactor) Reduces Harmonics
ABB ACH Series Drives include a 5%
swinging choke. Filter chokes fall into
two categories: the Linear Chokes and the
Swinging Choke. A Linear Choke has an
inductance that is relatively constant up to
the rated value of current. These chokes
are designed so that they will not saturate
when carrying all of the load current.
The Swinging Choke is used in applications where the change in inductance
is inversely proportional to the change
in load current (such as variable torque
applications). A well designed swinging
choke provides the proper inductance to
ensure adequate ltering and the continuous ow of current through the rectier
for all levels of load current.
From the graph (at right), it can be seen
that the built-in swinging choke in all ABB
HVAC Drives allows the drive to deliver
over 25% less harmonics at partial loads
than a conventional 3% reactor; more
than 60% less harmonics than a drive with
no reactor!
The reduced harmonics means the drive
input current is the same as the output
current. No need to oversize branch circuit wiring to comply with NEC 430-2!
55% less harmonics at full load, better than 64% less harmonics at partial loads. (HVAC
Drives spend most of their operating hours at partial loads.)
