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.

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.
