ηVLT

The efficiency of the adjustable frequency drive 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 inputs 53 or 54, can be voltage or current.

Bus Reference

A signal transmitted to the serial communication port (FC 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, 20 mA) 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 0 V, 0 mA, 4 mA) 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 adjustable frequency drive.

There are two 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 braking energy generated in regenerative braking. This regenerative braking energy 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 positive displacement pumps and blowers.

1-5

Digital Inputs

The digital inputs can be used for controlling various adjustable frequency drive functions.

Digital Outputs

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

DSP

Digital Signal Processor.

Relay Outputs:

The adjustable frequency drive features two 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)

Initializing

If initializing is carried out (par. 14-22), the programmable parameters of the adjustable frequency drive 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 non-periodic duty.

LCP

The Local Control Panel (LCP) makes up a complete interface for control and programming of the adjustable frequency drive. The control panel is

detachable and can be installed up to 9.8 ft [3 m] from the adjustable frequency drive, i.e., in a front panel by means of the installation kit option.

The local control panel is available in two 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 ≡0.00079 in2(0.5067 mm2).

msb

Most significant bit.

NLCP

Numerical Local Control Panel LCP101

On-line/Off-line Parameters

Changes to on-line parameters are activated immediately after the data value is changed. Changes to offline parameters are not activated until you enter

[OK] on the LCP.

PID Controller

The PID controller maintains the desired speed, pressure, temperature, etc., by adjusting the output frequency to match the varying load.
