Introduction

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, 4–
20 mA, or a digital signal.
Automatic motor adaptation, AMA
The AMA algorithm determines the electrical parameters
for the connected motor at standstill and compensates for
the resistance based on the length of the motor cable.
Digital inputs
The digital inputs can be used for controlling various
functions of the frequency converter.
Digital outputs
The frequency converter provides 2 solid-state outputs that
can supply a 24 V DC (maximum 40 mA) signal.
Relay outputs
The frequency converter provides 2 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 and prevent overheating of the motor.
Initializing
If initializing is carried out (parameter 14-22 Operation
Mode), the programmable parameters of the frequency
converter return to their default settings.
Parameter 14-22 Operation Mode does not initialize
communication parameters, fault log, or fire mode log.
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.
Keypad
The keypad makes up a complete interface for control and
programming of the frequency converter. The keypad is
detachable on IP20 units and fixed on IP54 units. It can be
installed up to 3 m (9.8 ft) from the frequency converter,
that is, in a front panel with the installation kit option.
Lsb
Least significant bit.
MCM
Short for mille circular mil, an American measuring unit for
cable cross-section. 1 MCM = 0.5067 mm
Msb
Most significant bit.

On-line/Off-line parameters
Changes to on-line parameters are activated immediately
after the data value is changed. Press [OK] to activate off-
line parameters.
PI controller
The PI controller maintains the desired speed, pressure,
temperature, and so on, by adjusting the output frequency
to match the varying load.
RCD
Residual current device.
Set-up
Parameter settings in 2 set-ups can be saved. Change
between the 2 parameter set-ups and edit 1 set-up, while
another set-up is active.
Slip compensation
The frequency converter compensates for the motor slip by
giving the frequency a supplement that follows the
measured motor load keeping the motor speed almost
constant.
Smart logic control (SLC)
The SLC is a sequence of user-defined actions executed
when the associated user-defined events are evaluated as
true by the SLC.
Thermistor
A temperature-dependent resistor placed where the
temperature is to be monitored (frequency converter or
motor).
Trip
A state entered in fault situations, for example, if the
frequency converter is subject to an overtemperature or
when the frequency converter is protecting the motor,
process, or mechanism. Restart is prevented until the cause
of the fault does not exist and the trip state is canceled by
activating reset or, sometimes, by being programmed to
reset automatically. Do not use trip for personal safety.
Trip lock
A state entered in fault situations when the frequency
converter is protecting itself and requiring physical
intervention, for example, if the frequency converter is
subject to a short circuit on the output. A locked trip can
only be canceled by cutting off mains, removing the cause
of the fault, and reconnecting the frequency converter.
Restart is prevented until the trip state is canceled by
activating reset or, sometimes, by being programmed to
reset automatically. Do not use trip lock for personal safety.
