Introduction
Preset reference
A defined preset reference to be set from -100% to +100%
of the reference range. Selection of 8 preset references via
the digital terminals. Selection of 4 preset references via
the bus.
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
parameter 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
parameter 3-02 Minimum Reference.
1.2.5 Miscellaneous
Analog inputs
The analog inputs are used for controlling various
functions of the frequency converter.
There are 2 types of analog inputs:
•
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, or 4–
20 mA.
Automatic motor adaptation, AMA
The 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 brake power increases the DC-link 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 2 solid-state outputs that
can supply a 24 V DC (maximum 40 mA) signal.
ETR
Electronic thermal relay is a thermal load calculation based
on present load and time. Its purpose is to estimate the
motor temperature.

Programming Guide
FC standard bus
Includes RS485 bus with FC protocol or MC protocol. See
parameter 8-30 Protocol.
Initializing
If initializing is carried out (parameter 14-22 Operation Mode
or 2 finger reset), 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.
LCP
The local control panel makes up a complete interface for
control and programming of the frequency converter. The
LCP is detachable. With the installation kit option, the LCP
can be installed up to 3 m (9.8 ft) from the frequency
converter in a front panel.
GLCP
The graphic local control panel (LCP 102) interface for
control and programming of the frequency converter. The
display is graphic and the panel is used to show process
values. The GLCP has storing and copy functions.
NLCP
The numerical local control panel (LCP 21) interface for
control and programming of the frequency converter. The
display is numerical and the panel is used to show process
values. The NLCP has storing and copy functions.
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
On-line/off-line parameters
Changes to on-line parameters are activated immediately
after the data value is changed. To activate changes to off-
line parameters, press [OK].
Process PID
The PID control maintains speed, pressure, and
temperature by adjusting the output frequency to match
the varying load.
PCD
Process control data.
Power cycle
Switch off the mains until the display (LCP) is dark, then
turn power on again.
Power factor
The power factor is the relation between I
