For the whole sugarcane mill line, located in the first press, the selection of the motor magnification 1.4 times, the remaining VFD magnification 1.2 times.

The GD5000 power cells don't has pre-charging circuit, but the whole VFD has a buffer circuit, which can pre-charge and buffer the cells.

The main interface cannot be accessed

First, determine the model of HMI. If it is TPC1062KI mode, it is a hardware problem. If it is TPC1061TH mode, first write HMI program to try. If the problem can not be solved, need to replace the HMI.

According to customer's requirements, we can supply  gear switch cabinets and  soft starters.

Check whether the power cell IGBT and drive board are abnormal; Whether there is abnormal insulation between VFD and motor.

In the deceleration process of GD5000 VFD, 300Hz high frequency voltage is superimposed on the base frequency 0-50Hz, increase motor stator loss, so as to achieve the purpose of fast braking.

Yes. INVT MVD has itself Internet of Things platform .Support INVT standard design or customized requirements.

Due to MVD is the stepless speed regulating device，the acceleration time is from 0-3600s,so the impusle current is the same as the motor rated current.

Yes. INVT MVD power cells can replace use. In the MVD all power cells are the same include hardware and software, so it can replace by each other.
