ABB ACS800 Multidrives Overview

Overview of the Construction

A multidrive is made up of several different units. These sections are called multidrive units. The most important units are:

Drive Units

Inverters have built-in capacitors for smoothing the voltage of the DC busbars. The electrical connection to the common DC busbar is fuse protected. However, an optional fuse switch with a capacitor charging device can be selected to disconnect the whole drive unit. Each inverter has a drive control unit (DCU) which contains the RMIO board and optional I/O modules. Several different I/O extension modules for different functions such as control, monitoring and measurement purposes are available. A separate pulse encoder interface module is also possible. Other optional features include the prevention of unexpected start-up for the inverters to provide a safe interlock for the system.

Diode Supply Unit (DSU)

A diode supply unit is used in non-regenerative drive systems to convert three-phase AC voltage to DC voltage. A 12-pulse bridge configuration can be implemented with the unit supplied by a three-winding transformer with a thirty degree phase shift between secondary windings. A diode supply unit is controlled by an RMIO board similar to drive units and IGBT supply units. This allows parameter setting, monitoring and diagnostic with CDP312R control panel, DriveWindow and fieldbuses.

IGBT Supply Unit (ISU)

An IGBT supply unit is used in regenerative drive systems to convert three-phase AC voltage to DC voltage. In power control it gives the same firm but gentle performance as DTC gives in motor control

The main circuit consists of a main switch, a filter and a converter. The converter is hardware compatible with drive units. The converter can operate in both motoring and generating modes. The DC voltage constant and the line current sinusoidal. The control also provides a near unity power factor. The control performance is excellent due to the ultra-fast control technology, the same as in DTC.

A fully regenerative IGBT supply unit with power factor 1 requires no power compensation. The unit can also boost DC voltage e.g. when the line voltage is low. Harmonic content remains extremely low due to DTC control and LCL filtering.

Thyristor Supply Unit (TSU)

A thyristor supply unit is used in regnerative drive systems to convert three-phase AC voltage to DC voltage. The thyristor supply unit contains two 6-pulse thyristor bridges in antiparallel connection. It has the ability to regenerate back to the mains, providing considerable energy savings with applications having excessive braking powers. A 12-pulse bridge configuration can be implemented with two thyristor supply units supplied by a three-winding transformer. This configuration reduceds harmonics in the supply network.

Paralle Connected Supply Units

It is possible to connect two supply units in parallel to teh same DC bus to get higher power or redundancy. These two units will be located at the rear ends of the drive DC bus. This possibility concerns parallel connection of two diode supply units (DSU+DSU), two IGBT supply units (ISU+ISU), or a DSU and an ISU to the same DC bus.

Higher power is needed, for example, in high power applications where it gives more drive flexibility to connect drive units to the same DC bus, or for high overload requirements.

Redundancy is needed in critical processes and also when maintenance intervals are long

Using DSU+ISU connected in parallel is a solution for when the need for braking power is much lower than for motoring power. ISU is dimensioned for braking power and operates continuously, while DSU is dimensioned for motor power minus ISU power.

Brake Unit

In resistor braking whenever the voltage in the intermediate circuit of a frequency converter exceeds a certain limit, a braking chopper connects the circuit to a braking resistor.

Standard braking resistors are separately available in their own cabinets. Non-standard resistors can be used providing that the specified resistance value is not decreased and that the heat dissipation capacity of the resistor is sufficient for the drive application.

AC800M Control Unit (optional)

The multidrive concept also includes the control unit for the AC800M and S800 I/O. The control unit is equipped with communication interfaces, power supplies and the front devices necessary for the automation equipment.

ACS800 Liquid-Cooled Multidrives

Advanced Liquid Cooling

The ACS800 liquid-cooled multidrive with direct liquid cooling and robust design is an ultimate solution for various applications where space savings and silent operation is a must.

Since the coolant takes care of 98% of the heat losses, no additional filtered air-cooling is needed. This decreases the noise level and increases the total efficiency of the converter installation. The high-efficiency liquid cooling removes the need for air-conditioning in the installation rooms, bringing the installation and operation costs down. The totally enclosed cabinet structure makes the ACS800 liquid-cooled multidrives perfect for harsh environmental conditions.

The ACS800 liquid-cooled multidrives are available from 1.1 kW up to 5600 kW at 380 to 690V supply voltage.

Customer Specific Design

The modular hardware design and advanced software features of the liquid-cooled multidrive enable the most sophisticated drive solutions for both induction and permanent magnet motors. Our customized solutions provide the optimum customer benefits.

The design meets the internal standards and marine classification requirements. ABB's extensive application and product know-how is at your service.

Intelligence and High Availability

The ABB ACS800 liquid-cooled series has a number of unique features as standard, and which are not available in previous generations of ABB drives, nor in existing competitor's drives.

These include:

  • Built-in redundancy through parallel connected modules - each module is a complete three-phase inverter
  • Ability to run with partial load even when one of the modules is not operating - enabling higher drive availability and greater process uptime.

With ABB drives, you get more than the most reliable equipment and systems. ABB drives are backed by our full service and support network, which covers field service and training as well as spare parts. This ensures reliable and economic operation under all condtions.

"Compact and easy" - are the watchwords to describe the entire ACS800 liquid-cooled drive range. They demonstrate how technology enables ABB to add more and more features into a shrinking space - and still give the benefits of easy installation, access and use.

Nominal Ratings

Icont. max: rated current available continuously without overloadability at 40 °C.
Imax: maximum output current. Available for 10 s at start, otherwise as long as allowed by drive temperature.

Typical Ratings

No-overload use

Light-overload Use

IN: continuous current allowing 110% IN for 1 min / 5 min at 40 °C.
PN: typical motor power in light-overload use.

Heavy-duty Use

Ihd: continuous current allowing 150% Ihd for 1 min / 5 min at 40 °C.
Phd: typical motor power in heavy-duty use.


The current ratings are the same regardless of the supply voltage within one voltage range.

The ratings apply in 40 °C ambient temperature.
In lower temperatures teh ratings are higher (except Imax(.

The rated current of the ACS800 must be higher than or equal to the rated motor current to achieve the rated motor power given in the table.
