References:
Analog Reference
A signal transmitted to the analog inputs 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).
Ref
MAX
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.
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 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.

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

.
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 out-
put frequency to match the varying load.
Pulse Input/Incremental Encoder
An external, digital pulse transmitter used for feeding back information on motor speed. The en-
coder 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 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 SLC. (Parameter group 13-xx).
FC Standard Bus
Includes RS 485 bus with FC protocol or MC protocol. See parameter 8-30.
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 pre-
vented 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 re-
connecting 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 (VVC
plus
) im-
proves 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 indicates to which extent the
frequency converter imposes a load on the
mains supply.
The lower the power factor, the higher the
I

In addition, a high power factor indicates that the different harmonic currents are low.
The FC 300 frequency converters' built-in DC coils produce a high power factor, which minimizes
the imposed load on the mains supply.
The voltage of the frequency converter is dangerous whenever connected to mains.
Incorrect installation of the motor, frequency converter or fieldbus may cause dam-
age to the equipment, serious personal injury or death. Consequently, the instruc-
tions in this manual, as well as national and local rules and safety regulations, must
be complied with.
Safety Regulations
1. The frequency converter must be disconnected from mains if repair work is to be carried
out. Check that the mains supply has been disconnected and that the necessary time has
passed before removing motor and mains plugs.
2. The [STOP/RESET] key on the control panel of the frequency converter does not dis-
connect the equipment from mains and is thus not to be used as a safety switch.
3. Correct protective earthing of the equipment must be established, the user must be pro-
tected against supply voltage, and the motor must be protected against overload in
accordance with applicable national and local regulations.
4. The earth leakage currents are higher than 3.5 mA.
5. Protection against motor overload is not included in the factory setting. If this function
is desired, set par. 1-90 to data value ETR trip or data value ETR warning.
6. Do not remove the plugs for the motor and mains supply while the frequency converter
is connected to mains. Check that the mains supply has been disconnected and that the
necessary time has passed before removing motor and mains plugs.
7. Please note that the frequency converter has more voltage inputs than L1, L2 and L3,
when load sharing (linking of DC intermediate circuit) and external 24 V DC have been
installed. Check that all voltage inputs have been disconnected and that the necessary
time has passed before commencing repair work.
