FC 300 Design Guide
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 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 and cranes.
Digital inputs:
The digital inputs can be used for controlling various functions of the adjustable frequency drive.
Digital Outputs:
The drive 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.

Initializing:
If initializing is carried out (par. 14-22), the adjustable frequency drive returns to the default setting.
LCP:
The Local Control Panel (LCP) provides a complete interface for control and programming of the FC
300 Series. The control panel is detachable and can be installed up to 9.8 ft (3 meters) from the
adjustable frequency drive, i.e. in a front panel by means of the installation kit option.
lsb:
Least significant bit.
MCM:
Short for Mille Circular Mil, an American measuring unit for cable cross-section.
1 MCM ≡ 0.00079 in. 2
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 output frequency to match the varying load.
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.
