Ref
MAX
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
3-03 Maximum Reference.
Ref
MIN
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
3-02 Minimum Reference
Miscellaneous:
Advanced Vector Control
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 screw and scroll
refrigeration compressors.
Digital Inputs
The digital inputs can be used for controlling various
functions of the adjustable frequency drive.
Digital Outputs
The adjustable frequency 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.

Design Guide
GLCP
Graphical Local Control Panel (LCP102).
Initializing
If initialization is carried out (14-22 Operation Mode), 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 makes up a complete interface for
control and programming of the adjustable frequency
drive. The LCP is detachable and can be installed up to
10 ft [3 m] from the adjustable frequency drive, i.e., in a
front panel by means of the installation kit option.
The LCP is available in two versions:
lsb
Least significant bit.
MCM
Short for Mille Circular Mil, an American measuring unit for
cable cross-section. 1 MCM ≡ 0.00078 in
msb
Most significant bit.
NLCP
Numerical Local Control Panel LCP 101.
Online/Offline Parameters
Changes to online parameters are activated immediately
after the data value is changed. Press [OK] to activate
changes to offline 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 four set-ups. Change between
the two parameter set-ups and edit one set-up, while
another set-up is active.
SFAVM
Switching pattern called Stator Flux-oriented Asynchronous
Vector Modulation (14-00 Switching Pattern).
