Abbreviations/Definitions Description
ED Duty cycle
ELCB Earth Leakage Circuit Breaker
ETR Electronic thermal relay is a thermal load calculation based on present load and
time. Its purpose is to estimate the motor temperature
Flux Vector If compared with standard voltage/frequency ratio control, Flux Vector improves
thedynamicsandthestability,bothwhen the speed reference is changed and
in relation to the load torque
Incremental encoder An external, digital pulse transmitter used for feeding back information on motor
speed. The encoder is used in applications where high accuracy in speed control
is required
Initializing If initializing is carried out (see parameter 620), the frequency converter returns to
the factory setting
KTY Semiconductor temperature sensor
LCP The Local Control Panel, which makes up a complete interface for control and
programming of the frequency converter. The control panel is detachable and
may, as an alternative, be installed up to 3 metres away from the frequency
converter, ie. in a front panel, by means of the installation kit option
Manual initialisation Press the [CHANGE DATA] + [MENU] + [OK] keys at the same time as power-up
to carry out manual initialisation. See also Parameter 620.
Note that manual initialisation is only to be used if the reset function does not work!
MCM Stands for Mille Circular Mil, an American measuring unit for cable cross-section
1 MCM=0.5067mm

NEC National Electrical Code
NTC Negative Temperature Coefficient resistor
On-line/off-line parameters On-line parameters are activated immediately after the data value is changed.
Off-line parameters are not activated unt
il OK has been entered on the control unit
OP Open Loop
OVC Over Voltage Control
PELV Protective Electrical Low Voltage. According to EN 50178
ppr Puls per revolutions
RPM Revolutions per minute
Thermistor A temperature-dependent resistor placed where the temperature is to be
monitored (VLT or motor)
Trip A state which occurs in different situations, eg. if the frequency converter is
subject to a live zero war
ning. A trip can be cancelled by pressing Reset
Trip locked Astatewhichoccursindif
ferent situations, eg. if the frequency converter is
subject to an overtemperature. A locked trip can be cancelled by cutting off
mains and restarting the frequency converter and pressing Reset
