Starvert iG5
Reduced size
Enhancing its performance the iG5 shows much smaller size compares to the previous model, the iG series.
Maximum 50% of total volume has been reduced in iG5 in order to mount it easily on smaller control panel and DIN rail with less weight. It allows more cost effective panel construction and system design.
Built-in communication interface and PC monitoring software
The iG5 has built-in the most popular communication interfaces such as Modbus-RTU and RS232/485. The iG5 has the small inverter features and standard medium drive features together.
The "DriveviewTM" software offers Window® based computer monitoring tool through RS485 interface with graphic capture, keypad emulator, parameter edit and text monitor. It is applicable for all LG inverters.
RS - 485
ModBus-RTUTM
Built-in PID control
It is valuable in process control. The built-in PID controller controls flow, temperature, pressure, etc. through the proportional, integral and differential calculus between the feedback value and reference value in closed loop.
Space vector PWM technology
The Space vector technology is being adopted in all LG drives. It features outstanding performance in its control characteristics. It has low total harmonic distortion, low current ripple, low torque ripple, low motor temperature rise, and better voltage utilization. It is a basic control platform of the iG5 drive. The advantages of Space vector PWM technology are being proved in many applications.

Features & Selection Guide
Optimum acceleration and deceleration
To achieve a maximum torque during the acceleration and deceleration, "trip free" function is activated. The 32-bit DSP CPU monitors the current transition during the acceleration and deceleration to program an optimum curve that is under the trip-triggering level.

PNP and NPN switchable duals signals
The iG5 has both PNP and NPN signals in order to controlled by PLC or outside controller.
Regardless the type of PLC or type of control signal, iG5 can work with positive 24Vdc and negative 24Vdc.
