Ref
MIN
Determines the relationship between the reference input at
0% value (typically 0V, 0mA, 4mA) and the resulting
reference. The minimum reference value set in
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, 0-20mA and 4-20mA
Voltage input, 0-10V DC (FC 301)
Voltage input, -10 - +10V DC (FC 302).
Analog Outputs
The analog outputs can supply a signal of 0-20mA, 4-20mA.
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 frequency converter features two Solid State outputs
that can supply a 24V DC (max. 40mA) 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.

Initialising
If initialising is carried out (
), 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 non-
periodic duty.
LCP
The Local Control Panel makes up a complete interface for
control and programming of the frequency converter. 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 = 0.5067mm

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

Power Cycle
Switch off the mains until display (LCP) is dark – then turn
power on again
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 (
).
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 Smart Logic Controller. (Par. group 13-**
