Injection Molding machines is a quite common application, because of that, Delta develop several solution depending on the different type of injection moldign machine.
In frirst place, we develop specific solution for this application called HES
This system provides precise pressure and flow controls, with our Delta key point in power: The energy savings.
In this moments, this product is under field test in Asia, and really soon on the rest of the world!
But If you want to take a look over our technology, check the below presentation
But for standard systems we got another solution.
Probably many of you already hear about our new C2000 Delta Inverter series, and possibly many of you already work with it in some application.
So this is one of the multiple ways to squeeze the capabilities of this versatile product.
The keypoint in this system is use the internal PLC and the PG card (encoder feedback) of C2000 to create a standalone control system able to adjust itself without any extra controller.
On the below links you will find the parameter configuration and PLC program to beable to test by yourselves.

And to have full explanation of the application, don´t hesitate to download the following presentation.
C2000 for Injection Molding Machine
Don´t hesitate to test with your Injection molding machines customers!
And let us know your results

Dear Sir,
I have installed the Delta VFD-VJ in master-salve configuration for 45KW as master and 30KW as slave. The machine ran perfectly fine for about 5 months then after that, the master drive randomly trips on GFF.
I have cross checked the Motor cable.
Checked the earthing.
Used the Power Analzer to monitor the input and output of the drive, found OK.
Still the drive trips randomly on the GFF.
Have no Doubts on the Motor winding.
Got replaced the Power and the Control card from the Delta Service Center one before, even then no resolution.
Besides, i have no info of the THD in the VFD-VJ manual, please guide for the Current and Voltage THD and its relation with the GFF. And, please help with the tolerance level of THD on VFD-VJ
