ABB general purpose drives 

ABB general purpose drives are simple to buy, install, 

configure and use, saving considerable time. They are 

widely available through ABB channel partners. The drives 

have common user and process interfaces with fieldbuses, 

common software tools for sizing, commissioning, 

maintenance and common spare parts.

Applications

ABB general purpose drives can be used in a wide range 

of industries. Typical applications include pump, fan and 

constant torque use, such as conveyors. ABB general 

purpose drives are ideal in those situations where there is a 

need for simplicity to install, commission and use and where 

customizing or special product engineering is not required.

Ratings, types, voltages and construction

Type designation

Drive’s type designation (shown above and in column 7 of the 

tables on the right side) identifies your drive by construction, 

current rating and voltage range. Once you have selected the 

type designation, the frame size (column 8) can be used to 

determine the drives dimensions, shown on the next page.

Construction

“01” within the type designation (shown above) varies 

depending on the drive mounting arrangement, and power 

rating.

01 = wall-mounted

02 = free-standing

Voltages

The ACS550 is available in two voltage ranges:

4 = 380 to 480 V

2 = 208 to 240 V

Insert either “4” or “2”, depending on your chosen voltage, 

into the type designation shown above.

Normal use vs heavy-duty use. For the majority of pump, fan and conveyor 
applications, select “Normal use” fi gures. For high overload requirements, select 
“Heavy-duty use” fi gures. If in doubt contact your local ABB sales offi ce or your 
drives distributor.

Assistant control panel

The assistant control panel, which is delivered as standard, 

features a multilingual alphanumeric display for easy drive 

programming. The control panel has various assistants and 

a built-in help function to guide the user. It includes a real 

time clock, which can be used during fault logging and in 

controlling the drive, such as start/stop. The control panel 

can be used for copying parameters for back up or for 

downloading them to another drive. A large graphical display 

and soft keys make it extremely easy to navigate.

Options
Control interfaces

Panel mounting kits

To attach the control panel to the outside of a larger enclosure, 

two panel mounting kits are available. A simple and cost-

efficient installation is possible with the ACS/H-CP-EXT kit, 

while the OPMP-01 kit provides a more user-friendly solution, 

including a panel platform that enables the panel to be 

removed in the same way as a drive-mounted panel. The 

panel mounting kits include all hardware required, including 

3 m extension cables and installation instructions.

How to select options

The options shown in the table are available within the ACS550 

range. Most of them have an associated 4-figure option code, 

which is shown in the table. It is this code that replaces B055 

in the type code above. External options require a separate 

order line and material or type code number.

Basic control panel

The basic control panel features a single 

line  numeric display. The panel can be 

used to control the drive, set the parameter 

values or copy them from one drive to 

another.

FlashDrop tool

ACS550 drives have an interface for a FlashDrop tool. 

FlashDrop is a powerful palm sized tool for fast and easy 

parameter selection and setting of an unpowered drive. The 

user can hide each parameter/group from the drive’s display, 

which protects the drive and connected machinery. For more 

information on the FlashDrop tool, please see page 10.

Relay output extension option module

This plug-in option offers three additional relay outputs. They 

can be used, for example, in pump and fan control or many 

supervisory functions. All the relays can be programmed 

to on/off by using the assistant control panel’s clock. 

Alternatively, fieldbus can be used to control any external 

components in the system.

Encoder feedback option module

The general purpose drives can accommodate an encoder 

module. Using an encoder for speed feedback is a straight 

forward way to increase motor control in many applications.

Plug-in fieldbus module

The plug-in fieldbus options bring connectivity to major 

automation systems. A single twisted pair avoids large 

amounts of conventional cabling,thereby reducing cost and 

increasing system reliability.

ACS550 supports the following fieldbus options:

 

− DeviceNet

TM

 

− LonWorks

®

 

− PROFIBUS DP

 

− CANopen

− ControlNet

FlashDrop tool

FlashDrop is a powerful palm sized tool for fast and easy 

parameter selecting and setting. It gives the possibility to 

hide selected parameters to protect the machine. Only the 

parameters needed in the application are shown. The tool can 

copy parameters between two drives or between a PC and a 

drive. All the above can be done without a power connection 

to the drive. The interface for FlashDrop is available in all wall-

mounted units.

DrivePM

DrivePM (drive parameter manager) is a tool to create, edit and 

copy parameter sets for the FlashDrop tool. For each parameter/

group the user has a possibility to hide it, which means that the 

drive user does not see the parameter/group at all.

DrivePM requirements

 

− Supported operating systems: 

Windows NT/2000/XP/Vista/7

FlashDrop package includes

 

− FlashDrop tool

 

− DrivePM software (CD-rom)

 

− User’s manual (hardcopy and PDF)

 

− RS232 cable for connection between PC and 

the FlashDrop tool

 

− Battery charger

DriveWindow Light

DriveWindow Light is an easy-to-use startup and maintenance 

tool for ACS550 drives. It can be used in an offline mode, 

which enables parameter setting at the office even before 

going to the actual site. The parameter browser enables 

viewing, editing and saving of parameters. The parameter 

comparison feature makes it possible to compare parameter 

values between the drive and the file. With the parameter 

subset you can create your own parameter sets. Controlling 

of the drive is naturally one of the features in DriveWindow 

Light. With this software tool, you can monitor up to four 

signals simultaneously. This can be done in both graphical 

and numerical format. Any signal can be set to stop the 

monitoring from a predefined level.

Startup wizards

Startup wizards make the setting of parameters easy. Simply 

launch the wizard, select an appropriate assistant eg, for 

setting analog outputs, and all parameters related to this 

function are shown together with help pictures.

3)

  Maximum switching frequency to be used with du/dt fi lter is 4 kHz

Output chokes

Output chokes are used when motor cables above normal 

length are required.

Cable can be roughly 1.5 times standard cable length, see 

below.

Note:
An output choke does not improve the EMC performance of the drive. 
To fulfi l local EMC requirements use suffi cient RFI fi ltering.

Cooling and fuses

Cooling

ACS550 is fitted with cooling air fans. The cooling air must 

be free from corrosive materials and not above the maximum 

ambient temperature of 40 °C (50 °C with derating). For more

The future of your drives depends on the service 
you choose. 

Whatever you choose, it should be a well-informed decision. 
No guesswork. We have the expertise and experience to 
help you find and implement the right service for your drive

questions:

 

−

Why should my drive be serviced?

 

−

What would my optimal service options be?

From here, you have our guidance and full support along the 
course you take, throughout the entire lifetime of your drives.
