Chapter 1 General Description
The Eurotherm Drives Inverters described in this manual are suitable for the speed control of
standard 3-phase induction motors.
The Inverters use advanced microprocessor based technology to generate a variable frequency
variable voltage output, the control algorithm combining unique space Vector Pulse Width
Modulation control strategy with quiet pattern operation. The Inverters' control terminals are
galvanically isolated from power circuits to allow easy system interconnection. The controller is
protected against both phase to phase and phase to earth short circuits, overloads, and excessive
voltages via an intelligent monitoring strategy, thus avoiding nuisance tripping and giving trouble
free operation.
The Inverters require either a single phase 2 wire supply of 220/240 Volts, 50/60Hz or a 3-phase
3 wire supply, at 220/240V, 50/60Hz.
The 582 is available in two versions:
i)0.37/0.55kW single phase supply only
ii) 0.55/0.75kW single or 3-phase supply possible
The 583 is available in two versions:
i)1.1/1.5kW single or 3-phase supply
ii) 1.5/2.2kW single or 3-phase supply
The 5831 is available in two versions:
i)0.37/0.55/0.75kW single or 3-phase supply
ii) 1.1/1.5kW single or 3-phase supply
All versions feature power derating by simple switch selection. Note that all controllers are
shipped with the switches set to the lower rating.
The Inverters' output frequency ranges from 0 - 100/120Hz with varying voltage/frequency
characteristics suitable for either constant torque applications or efficient operation of fans and
centrifugal pumps.
The 582/583 Inverters are available in either IP00 or IP20 enclosures. The IP20 version can be
supplied with the basic operator controls of speed demand, direction and start/stop, requiring
only the power connections to be made to give a working system.
The 5831 is the IP54 version of the Inverter family. It can be supplied as a simple enclosed
version or with basic operator controls.
An option card is also available which can be fitted in the inverter to allow use of a current
reference instead of the standard voltage reference.
The inverters are fully compliant with the requirements of the EMC directive. As standard they
meet the industrial immunity requirements of the draft generic standard prEN50082-2 (1992),
and with the addition of filters, and correct installation meet the ‘residential, commercial and
light industrial’ emission requirements of the generic standard EN50081-1 (1992).
WARNING
Dangerous voltages remain present in the drive for a few minutes after power is removed, as
indicated by the link charge LED. Allow 5 minutes after the power is removed for the link
capacitors to discharge before working on the drive or ancillary equipment.
***** DO NOT CONNECT TO 415V SUPPLY. USE ONLY 220/240V *****
