FC 300 Design Guide
Ref
MAX
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.
Ref
MIN
Determines the relationship between the reference input at 0% value (typically 0 V, 0 mA, 4 mA)
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 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 (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 braking energy generated in regenerative
braking. This regenerative braking energy increases the intermediate circuit voltage, while a brake
chopper ensures that the energy 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 adjustable frequency drive.
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.
