Introduction
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 ()
Voltage input, -10 - +10 V DC ().
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 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 frequency converter 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.
Hiperface ®
Hiperface ® is a registered trademark by Stegmann.
Initializing
If initializing is carried out (par.14-22 Operation Mode), the frequency converter 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.
keypad
The Local Control Panel (keypad) makes up a complete interface for control and programming of the frequency
converter. 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.
MCM
Short for Mille Circular Mil, an American measuring unit for cable cross-section. 1 MCM = 0.5067 mm 2 .
