Miscellaneous:

Advanced Vecter Control

Analog Inputs

The analog inputs are used for controlling various

functions of the frequency converter.

There are 2 types of analog inputs:

Current input, 0-20 mA and 4-20 mA

Voltage input, 0-10 V DC.

Analog Outputs

The analog outputs can supply a signal of 0-20 mA, 4-20

mA, or a digital signal.

Automatic Motor Adaptation, AMA

AMA algorithm determines the electrical parameters for

the connected motor at standstill.

Brake Resistor

The brake resistor is a module capable of absorbing the

brake power generated in regenerative braking. This

regenerative braking power increases the intermediate

circuit voltage and a brake chopper ensures that the

power is transmitted to the brake resistor.

CT Characteristics

Constant torque characteristics used for screw and scroll

refrigeration compressors.

Digital Inputs

The digital inputs can be used for controlling various

functions of the frequency converter.

Digital Outputs

The frequency converter features 2 Solid State outputs that

can supply a 24 V DC (max. 40 mA) signal.

DSP

Digital Signal Processor.

Relay Outputs

The frequency converter features 2 programmable Relay

Outputs.

ETR

Electronic Thermal Relay is a thermal load calculation

based on present load and time. Its purpose is to estimate

the motor temperature.

GLCP

Graphical Local Control Panel (LCP102)

Initialising

If initialising is carried out (14-22 Operation Mode), the

programmable parameters of the frequency converter

return to their default settings.

Intermittent Duty Cycle

An intermittent duty rating refers to a sequence of duty

cycles. Each cycle consists of an on-load and an off-load

period. The operation can be either periodic duty or none-

periodic duty.

LCP

The Local Control Panel makes up a complete interface for

control and programming of the frequency converter. The

LCP is detachable and can be installed up to 3 metres

from the frequency converter, i.e. in a front panel by

means of the installation kit option.

The LCP is available in 2 versions:

Numerical LCP101 (NLCP)

Graphical LCP102 (GLCP)

lsb

Least significant bit.

MCM

Short for Mille Circular Mil, an American measuring unit for

cable cross-section. 1 MCM ≡ 0.5067 mm

msb

Most significant bit.

NLCP

Numerical Local Control Panel LCP 101

On-line/Off-line Parameters

Changes to on-line parameters are activated immediately

after the data value is changed. Press [OK] to activate

changes to off-line parameters.

PID Controller

The PID controller maintains the desired speed, pressure,

temperature, etc. by adjusting the output frequency to

match the varying load.

RCD

Residual Current Device.

Set-up

Save parameter settings in 4 Set-ups. Change between the

4 parameter Set-ups and edit one Set-up, while another

Set-up is active.

SFAVM

Switching pattern called Stator Flux oriented Asynchronous

V ector M odulation (14-00 Switching Pattern).

Slip Compensation

The frequency converter compensates for the motor slip

by giving the frequency a supplement that follows the

measured motor load keeping the motor speed almost

constant.

Smart Logic Control (SLC)

The SLC is a sequence of user-defined actions executed

when the associated user-defined events are evaluated as

true by the SLC.

Thermistor

A temperature-dependent resistor placed where the

temperature is to be monitored (frequency converter or

motor).

Trip

A state entered in fault situations, e.g. if the frequency

converter is subject to an over temperature or when the

frequency converter is protecting the motor, process or
