!VLT

The efficiency of the frequency converter is defined as the ratio between the power output and the power

input.

Start-disable command

A stop command belonging to the group 1 control commands - see this group.

Stop command

See Control commands.

References:

Analog Reference

A signal transmitted to the analog input s 53 or 54, can be voltage or current.

Binary Reference

A signal transmitted to the serial communication port.

Preset Reference

A defined preset reference to be set from -100% to +100% of the reference range. Selection of eight

preset references via the digital terminals.

Pulse Reference

A pulse frequency signal transmitted to the digital inputs (terminal 29 or 33).

RefMAX

Determines the relationship between the reference input at 100% full scale value (typically 10 V, 20mA)

and the resulting reference. The maximum reference value set in par. 3-03.

RefMIN

Determines the relationship between the reference input at 0% value (typically 0V, 0mA, 4mA) and the

resulting reference. The minimum reference value set in par. 3-02.

Miscellaneous:

Analog Inputs

The analog inputs are used for controlling various functions of the frequency converter.

There are two types of analog inputs:

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

Voltage input, 0-10 V DC (FC 301)

Voltage input, -10 - +10 V DC (FC 302).

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 all applications such as conveyor belts, displacement pumps and

cranes.

Digital Inputs

The digital inputs can be used for controlling various functions of the frequency converter.

Digital Outputs

The drive features two Solid State outputs that can supply a 24 V DC (max. 40 mA) signal.

DSP

Digital Signal Processor.

ETR

Electronic Thermal Relay is a thermal load calculation based on present load and time. Its purpose is to

estimate the motor temperature.

Hiperface®

Hiperface®is a registered trademark by Stegmann.

Initialising

If initialising is carried out (par. 14-22), the frequency converter returns to the default setting.

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 (LCP) makes up a complete interface for control and programming of the FC 300

Series. The control panel 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.

lsb

Least significant bit.

msb

Most significant bit.

MCM

Short for Mille Circular Mil, an American measuring unit for cable cross-section. 1 MCM = 0.5067 mm2.

On-line/Off-line Parameters

Changes to on-line parameters are activated immediately after the data value is changed. Changes to

off-line parameters are not activated until you enter [OK] on the LCP.

Process PID

The PID regulator maintains the desired speed, pressure, temperature, etc. by adjusting the output fre-

quency to match the varying load.

Pulse Input/Incremental Encoder

An external, digital pulse transmitter used for feeding back information on motor speed. The encoder is

used in applications where great accuracy in speed control is required.

RCD

Residual Current Device.

Set-up

You can save parameter settings in four Set-ups. Change between the four parameter Set-ups and edit

one Set-up, while another Set-up is active.

SFAVM

Switching pattern called Stator Flux oriented Asynchronous Vector Modulation (par. 14-00).

Slip Compensation

The frequency converter compensates for the motor slip by giving the frequency a supplement that fol-

lows 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. (Parameter group 13-xx).

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 mechanism. Restart is prevented until

the cause of the fault has disappeared and the trip state is cancelled by activating reset or, in some cases,

by being programmed to reset automatically. Trip may not be used for personal safety.

Trip Locked

A state entered in fault situations when the frequency converter is protecting itself and requiring physical

intervention, e.g. if the frequency converter is subject to a short circuit on the output. A locked trip can

only be cancelled by cutting off mains, removing the cause of the fault, and reconnecting the frequency

converter. Restart is prevented until the trip state is cancelled by activating reset or, in some cases, by

being programmed to reset automatically. Trip may not be used for personal safety.

VT Characteristics

Variable torque characteristics used for pumps and fans.

VVCplus

If compared with standard voltage/frequency ratio control, Voltage Vector Control (VVCplus) improves the

dynamics and the stability, both when the speed reference is changed and in relation to the load torque.

60° AVM

Switching pattern called 60°Asynchronous Vector Modulation (par. 14-00).

Power Factor

The power factor is the relation between I1and

IRMS.

Power factor

xU xI

xcos

xU xI

RMS

The power factor for 3-phase control:

xcos

ϕ1

RMS

since cos

ϕ1=1

The power factor indicates to which extent the

frequency converter imposes a load on the mains

supply .

The lower the power factor, the higher the IRMS for

the same kW performance.
