effective configuration”
 Features

Sensorless vector control

The iC5 adopts sensorless vector control algorithm, and it improves not only the torque
control characteristics, but the speed controlability in an uncertain condition caused by
the load variation as well.

LS Drive iC5 Series

Auto tuning
The auto tuning algorithm in the iC5 sets the motor factors automatically that brings the
traditional commissioning difficulties mainly in low speed by the load variation and the low
torque generation to a settlement.

•Difficulty of measuring the motor constant •Input errors by an user

•Low torque in low speed •Low speed by the load variation •Setup by an expert

characteristic

•Setup by an user •mproving torque in low speed

•Auto tuning of the motor characteristics •Optimized motor control

PNP and NPN switchable dual signals

The iC5 provides PNP and NPN signals for outside controllers.
It works with 24Vdc regardless of the type of PLC or control signals.

Communication interface, ModBus-RTU

The iC5 provides the most popular communication interface, ModBus-RTU for remote
control by PLC or other devices.

Programmable PID process control

PID process control is used in iC5 to make speed corrections quickly with a minimal
amount of overshoot and oscillation for the control of flow, temperature, pressure and etc.

Tips on Installation

Warning :
Carefully read the instruction for installation and wiring of drives and relevant
devices. Normal operation is impossible in case of the improper system design
and wiring. These can shorten the life of the drive and damage it at the worst.

INDUCTORS FOR
VARIABLE SPEED DRIVES

The inductors manufactured with special magneticcores

are advisable for location: BETWEEN MAINS AND
VARIABLE SPEED DRIVE, in order to protect the
equipment from overvoltages, voltage surges and also
to limit the line current and the harmonics generated by
VSD. BETWEEN VARIBLE SPEED DRIVE AND MOTOR, to
absorb the voltage peaks in the motor terminals, when
the connection cables are long or there are more than
one motor in parallel, for having a better efficiency and
to eliminate the humming noise of the motor.
POWER LINE FILTERS

The family of filters manufactured by LIFASA has been

specially developed and approved for its application
with variable speed drives, to assure the compliance of
the EMC (Electro Magnetic Compatibility) and the LV
safety European Directives, in both industrial and
domestic environments.

VARIABLE SPEED DRIVES

•Powers from 0.37 to 375 kW

•Sngle/three phase voltages 220/230 Vac
•Three phase voltages 380/460 Vac
•Sensorless vector control, V/F closed loop
•Removable console with copy function
•RS485 communication facilities as standard
•Autotuning
•Special parameters for special applications
OUTPUT LC FILTERS

The commutation of the IGBT's at high frequency (PWM)

provokes an output voltage with peaks up to 1300 V The
LC filter - low pass - reduce the dV/dt converting the
voltage in a sinus waveform, eliminating all the isolation
problems in the motor and the emission of interference
from the cables.
