PID control
In the centrifugal fan and pump field, PID control is provided as a standard function in order to maintain a constant process
control of pressure, flow and oil level. This function includes Pre-PID, Sleep and Wake up and output inverse sub-functions.
Dual PID
In case of a external PID control or cascade PID control, the built-in Dual PID function of iP5A allows various systems.
Pre Heating function
When inverter is used in damp places such as green-house, this function can prevent motor’s damage and inverter’s failure
from damp.
Flying Start function
In case of more than 2 fans operated in one system or heavy fan spinning by inertia, iP5A detects motor’s speed and start to
operate by considering it.
Energy Saving and
High Efficiency
LS iP5A, uniquely designed for fan and pump,
guarantees a certain degree of energy saving by
realizing the system effectiveness optimization.
Sleep and Wake-up function
Sleep and Wake-up function can stop inverter’s operation in extremely low weighted load situation. And if the load is
restored to a normal situation, inverter will restart. This mechanism ultimately brings energy saving result of entire system.
Multi Motor Control
Through this Multi Motor Control function, a number of
motors can be controlled simultaneously without having
any extra controllers. MMC function surely provides energy
savings and cost down effect.

Safety Stop
When unexpected power-failure blocks power supply,
inverter stops motor by using the inertia energy of load that
prevents unexpected second accident (Parameter setting is
required).
Current Leakage Reduction Algorithm
Damp condition is subject to cause system failure due to the
current leakage. And iP5A invents LS own PWM algorithm to
blow out this danger.
Flux Braking Algorithm
This can make the deceleration time shorter than the
regular one, so it make effect to system efficiency.
Automatic Carrier Frequency change
Considering ambient temperature, iP5A can amend the
carrier frequency automatically.
NPN/PNP Input
iP5A has both NPN and PNP input, and you can select one of
them easily.
Abundant I/O suggestion
iP5A is able to serve abundant I/O
Various Units of Display
Various units of display are supported in iP5A, so users can
recognize operation status easily.
Built-in 485 and Optional
Communication
Built-in 485 of iP5A enables to set up communication
system by itself without any additional device. And optional
communication suggestion of iP5A can satisfy users who
want to construct their own system.
