Sensorless vector control high torque
Built-in sensorless vector control realizes the superb speed control and powerful
high torque.
Ground-fault protection function during running
Ground-fault protection of output terminal is possible during running.
Cooling fan control according run pattern
By controlling the cooling fan, iG5A provides a virtually quite environment
according motors run and stop.
Auto carrier frequency changes according temperature
When the internal temperature of the inverter increses too high, it is detected and
then the inverter control’s the carrier frequency automatically.
This function automatically eliminates the temperature increase factor of inverter,
thereby it keeps a sounded operation.

Smart
Easy
Flexibility
More convenient interface
The parameter setup became easier by adopting the 4 directions key.
Easy change of the fan
In case of the fan breakdown, it is always changeable by the user as iG5A has
been designed to a easy fan changeable structure.
Built-in communication
By the built-in the RS485 LG bus and the Modbus-RTU communications iG5A
came to easy application to the communication environment.
Built-in PID control
The built-in process PID function enables controlling the flow-rate,oil-pressure,
temperature etc, without any extra controller.
Control from -10V to +10V
Controlling forward and reverse run became possible with inputting voltage
signals that ranges from -10V to +10V.
PNP/NPN input
Both PNP and NPN inputs became possible and these enable to use the outer
power. To do so, the user will be given wider choices of selecting the controller.
