YASKAWA – High-function, Fully-vector Control Inverter Varispeed G7 Inverter

Category: Tag:



・ The “3-level control method” solves problems of motor insulation damaged by surge voltage and motor bearing electric corrosion caused by bearing voltage. Leakage current and noise are greatly reduced.
・ V/f control and vector control both with and without a pulse generator, all in a single unit.
Capable of operating precision machinery and those requiring multiple drives.
・ Rotation-type auto-tuning method and the new static auto-tuning are available.
・ Various inputs and outputs such as pulse train input, pulse train monitor, etc. The logic level (sink, source) of the input terminals can be changed. An external 24 V power supply can be also applied.
・ The 5-line LCD operator for easier confirmation of required information.
A copy function makes it easy to quickly program multiple drives with identical settings.
・ 12-pulse input for significantly less harmonic distortion.
・ A wide range of power supply voltage (Three-phase 200 V class: 200 to 240 V; Three-phase 400 V class: 380 to 480 V).
・ Communications option unit supports all major field networks.
