References:
Analog Reference
An analog signal applied to input 53 or 54. The signal can be either Voltage 0–10 V (FC 301 and FC 302) or -10–+10 V (FC 302) Current signal 0–20 mA
or 4–20 mA
Binary Reference
A signal applied to the serial communication port (RS 485 term 68 – 69).
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 reference applied to term 29 or 33, selected by par 5-13 or 5-15 [32]. Scaling in par group 5-5*.
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
Maximum Reference .
RefMIN

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 (AutomationDrive FC 301)
Voltage input, -10–+10 V DC (AutomationDrive FC 302).
Analog Outputs
The analog outputs can supply a signal of 0–20 mA, 4–20 mA.
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 all applications such as conveyor belts, displacement pumps and cranes.
Digital Inputs
The digital inputs can be used for controlling various adjustable frequency drive functions.
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.
ETR
Electronic Thermal Relay is a thermal load calculation based on present load and time. Its purpose is to estimate the motor temperature.

Initializing
If initialization is carried out (par. 14-22
Operation Mode ), the adjustable frequency drive 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 adjustable frequency drive. The control panel 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.
NLCP
Numerical Local Control Panel interface for control and programming of adjustable frequency drive. The display is numerical and the panel is basically
used for display process values. The NLCP has no storing and copy function.
lsb
Least significant bit.
msb
Most significant bit.
MCM
Short for Mille Circular Mil, an American measuring unit for cable cross-sections. 1 MCM = 0.5067 mm2.
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 output frequency to match the varying load.
PCD
Process Data
Pulse Input/Incremental Encoder
An external digital sensor used for feedback information of motor speed and direction. Encoders are used for high speed accuracy feedback and in high
dynamic applications. The encoder connection is either via term 32 and 32 or encoder option MCB 102.
RCD

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
Switching Pattern ).
Slip Compensation
The adjustable frequency drive 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.
(Parameter group 13-xx Smart Logic Control (SLC).
STW

Thermistor:
A temperature-dependent resistor placed where the temperature is to be monitored (adjustable frequency drive or motor).
THD
Total Harmonic Distortion state the total harmonic contribution.
Trip
A state entered in fault situations, e.g., if the adjustable frequency drive is subject to an overtemperature or when the adjustable frequency drive is
protecting the motor, process or mechanism. Restart is prevented until the cause of the fault has disappeared and the trip state is canceled 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 adjustable frequency drive is protecting itself and requiring physical intervention, e.g., if the adjustable
frequency drive is subject to a short circuit on the output. A locked trip can only be canceled by cutting off line power, removing the cause of the fault,
and reconnecting the adjustable frequency drive. Restart is prevented until the trip state is canceled 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 (VVCplus) improves 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
Switching Pattern ).
Power Factor
The power factor is the relation between I1and IRMS.
Power factor =
3 x U x I
1
cos ϕ
3 x U x IRMS
The power factor for 3-phase control:
=
I 1 x cos ϕ1
IRMS
=
I
1
IRMS
since cos ϕ1 = 1
The power factor indicates to which extent the adjustable frequency drive
imposes a load on the line power supply.
The lower the power factor, the higher the IRMS for the same kW per-
formance.
IRMS = I

In addition, a high power factor indicates that the different harmonic currents are low.
All Danfoss adjustable frequency drives have built-in DC coils in the DC link to increase the power factor and to reduce the THD on the line power supply.
