Altivar 38

Applications

The Altivar 38 is a frequency inverter for three-phase asynchronous motors powered

by a three-phase supply 360 V to 460 V in the power range 0.75 kW to 315 kW.

The Altivar 38 has been designed for state-of-the-art applications in heating,

ventilation and air conditioning (HVAC) in industrial and commercial buildings:

# ventilation

# air conditioning

# pumping

The Altivar 38 can reduce operating costs in buildings by optimizing energy

consumption whilst improving user comfort.

Its numerous integrated options enable it to be adapted to and incorporated into

electrical installations and sophisticated control systems.

The need for electromagnetic compatibility was taken into account at the outset of

designing the drive. Depending on the drive rating, filters and chokes are either built-

in or available as optional accessories.

Functions

The Altivar 38 ( ) is su pp lied ready for use in pumping and ventilation applications.

It comprises a terminal ( ) which can be used to modify programming, adjustment,

control or monitoring functions in order to adapt and customize the application to

meet individual customer requirements.

# Specific functions for pumping/ventilation :

5 Energy saving

5 Automatic catching a spinning load with speed detection (catch on the fly)

5 Adaptation of current limiting according to speed

5 Faster/slower, preset speeds

5 Integrated PI control, with preset PI references

5 Electricity and service hours meter

5 Motor noise reduction

# Protection functions :

5 Motor and fan thermal protection via PTC thermal probe

5 Protection against overloads and overcurrents in continuous operation

5 Machine mechanical protection via jump frequency function

5 Protection via multiple fault management and configurable alarms

# Easy to integrate into control systems :

5 4 logic inputs, 2 relay outputs, 2 analog inputs and 1 analog output

5 Plug-in I/O connectors

5 Display of electrical variables and operating indicators

5 An RS 485 multidrop serial link with M odb us protocol as standard in the drive This

serial link can be used to connect PLCs (

), a PC, communication gateways or one

of the available programming tools.

Options

# PowerSuite advanced dialogue solutions :

# Customizing the ap plic ation :

5 I/O extension cards (

5 Application cards ( ) :

pump switching, multi-motor function, multiple pa rameter settings and cycles

5 Communication cards for bus or network ( ) :

METASYS N2, Ethernet, Fipio, Uni-Telway/Modbus, Modbus Plus, AS-i,

Profibus DP, Interbus-S, CANopen, DeviceNet

5 Communication module for LonWorks bus (
