Extended I/O boards

The iS5 has several additional I/O boards that can be easily mounted into the connection terminal on control

board. Each I/O board is standardized for a specific I/O requirement.

The three main I/O boards are "Sub-board A", "Sub-board B" and "Sub-board C".

This helps system engineer to design most adequate and cost effective system 

using the exactly necessary number of I/Os and functions.

It is extendable and changeable in case of system upgrade or change.

The control parameters and detailed functions for these boards 

are not shown until any of them is inserted.

Diversity of communication interfaces

The iS5 provides most popular communication interfaces such as Device Net, Profibus DP, Modbus-RTU, 

RS485 and F-Net (LG proprietary protocol for LG PLC communication). 

The "DriveviewTM" software offers Window® based computer monitoring tool through RS-485 interface with

graphic capture, keypad emulator, parameter edit, and text monitor. It is applicable for all LG inverters

Built-in PID control

It is valuable in process control. The built-in PID algorithm controls flow, temperature, pressure, etc. through the

proportional, integral and differential calculus between the feedback value and reference value in closed loop.

The high speed CPU makes the calculation easy and fast.

Sensorless vector control

The iS5 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. 

The iS5 especially generates strong torque at a low speed range as shown below.

Auto tuning

The auto tuning algorithm in iS5 sets the motor factors automatically. It brings the traditional commissioning difficulties mainly in

low speed by the load variation and the low torque generation to a settlement.

Optimum acceleration and deceleration

To make a maximum torque during the acceleration and deceleration, so called "trip free" function is acting during acceleration

and deceleration. Both of Acceleration and deceleration may cause a trip in case that it is manually programmed. The 32-bit

DSP CPU monitors the current transition during the acceleration and deceleration to program an optimum curve that is under

the triptrigering level automatically.
