η
The efficiency of the frequency converter is defined as the
ratio between the power output and the power input.
Start-disable command
A stop command belonging to the group 1 control
commands - see this group.

References:
Analog Reference
An analog signal applied to input 53 or 54. The signal can
be either voltage 0-10 V or -10 -+10 V. Current signal is
0-20 mA or 4-20 mA.
Binary Reference
A signal applied to the serial communication port (RS-485
term 68–69).
Preset Reference
A defined preset reference, set between -100% and +100%
of the reference range. Select eight preset references via
the digital terminals.
Pulse Reference
A pulse reference applied to term 29 or 33, selected by
par. 5-13 or 5-15 [32]. Scaling in par. group 5-5*.
Ref
MAX
Shows the relationship between the reference input at
100% full scale value (typically 10 V, 20 mA) and the
resulting reference. Set the maximum reference value 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. Set the minimum reference value in
3-02 Minimum Reference.
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 to +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 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.

Initialising
If initialising is carried out (
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.
LCP
The local control panel (LCP) comprises a complete
interface for control and programming of the frequency
converter. The LCP is detachable and can be installed up
