How to Read this Design Gui...
Binary Reference
A signal applied to the serial communication port (FS-485
terminal 68-69).
Bus Reference
A signal transmitted to the serial communication port (FC
port).
Preset Reference
A defined preset reference set from -100% to +100% of
the reference range. Selection of eight preset references
via the digital terminals.
Pulse Reference
A pulse frequency signal transmitted to the digital inputs
(terminal 29 or 33).
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 is set in
3-03 Maximum Reference.
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 is set in
3-02 Minimum Reference.
Miscellaneous:
Analog Inputs
The analog inputs (current and voltage) are used for
controlling functions of the frequency converter. Current
input, 0–20 mA, and 4–20 mA. Voltage input, 0–10 V DC.
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
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 screw and scroll
refrigeration compressors.

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.
Relay Outputs:
The frequency converter features two programmable relay
outputs.
ETR
Electronic thermal relay is a thermal load calculation based
on present load and time. Its purpose is to estimate the
motor temperature.
GLCP:
Graphical local control panel (LCP102)
Hiperface®
Hiperface® is a registered trademark by Stegmann.
Initialising
If initialising is carried out (14-22 Operation Mode), the
programmable parameters of the frequency converter
return to their default settings.
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 none-
periodic duty.
LCP
The local control panel (LCP) makes up a complete
interface for control and programming of the frequency
converter. The LCP is detachable and can be installed up
to 3 metres from the frequency converter, in a front panel
with the installation kit option.
The LCPl is available in two versions:
•
•
lsb
Least significant bit.
MCM
Short for mille circular mil, an American measuring unit for
cable cross-section. 1 MCM ≡ 0.5067 mm
