FC 300 Design Guide
How to Read this Design Guide
Automatic Motor Adaptation, AMA:
AMA algorithm determines the electrical parameters for the connected m otor at standstill.
B
rake Resistor:
The brake resistor is a module capable of absorbing the brake power generated in regenerative
braking. This regenerative braking energy increases the intermediate circuit voltage and a brake
chopper ensur es that the power is transmitted to the brake resistor.
C
T Characteris tics:
Constant torque characteristics used for all applications such as conveyor belts and cranes.
D
igital inputs:
The digital inputs can be used for controlling various functions of the ad justable frequency drive.
D
igital Outputs:
The d rive features two solid state outputs that can supply a 24 V DC (max. 40 mA) signal.
Relay Outputs
The drive features two programmable Relay Outputs.

I
nitializing:
If initializing is carried out (par. 14-22), the adjustable frequency drive returns to the default setting.
L
CP:
The Local Control Panel (LCP) provides a complete interface for control and programming of the FC
300 Series. The control panel is d etacha ble and can be installed up to 9.8 ft (
3meters)fromthe
adjustable frequency drive, i.e. in a front panel by means of the installation kit option.
l
sb:
Least significant bit.
M
CM:
Short for Mille Circular Mil, an Am erican measuring unit for cable c
ross-section.

m
sb
Most significant bit.
O
n-line/Off-line Parameters:
Changes to on-line parameters are activated immediately a
fter the data value is changed. Changes
to off-line parameters are not activated until you enter [ OK] on the LCP.
P
rocess PID:
The PI D regula tor mainta ins the desired speed, pressure, temperature, etc. by adjusting
the output frequency to match the varying load.
P
ulse Input/Incremental Encoder:
An external, digital pulse transmitter used for fe eding back information on motor speed. The encoder
is used in applications where grea t accuracy in speed control is required.
R
CD:
Residual Current Device.
