Successful Application: Washing Machine

Long time ago I got the opportunity to program by myself an industrial Washing Machine.
In my case I remember to use:
– DOPAS35THTD -> Is what we got on this time.
– DTC1000 -> with PT100 sensor
– DVP10SX11R -> To be able to control the inverter using analog output, and using the analog input for pressure sensor)
– VFD-E inverter -> To be able to use OOB (out of balance) function specially designed for washing Machines.

OOB or Out of balance is a firmware instruction used during the spin stage, to stops automatically slows down the inverter when the clothes are not perfectly centred.
This special function is not really common on other brand inverters, so be aware washing machine makers!

In this case the Global Service Centre uses different kind of elements, but with the same result.

Don´t hesitate to take a look on the successful application document below

If you ever did application like that let us know your experiences, and If not now you know is possible.

Delta will be at SPS/IPC/Drives in Nuremberg 2012

Come to our both, we’ll be there!

Successful Application – Profibus communication with VFD-EL & CME-PD01

It’s well known that Profibus is quite extended within industrial enviroment.
But this doesn’t mean that you need to use Siemens inverter when the fieldbus network is already setup!

We know that Simatic Step7 is not a piece of cake…
So, on the tutorial below you will find step by step, how to manage Simatic Step7 to be able to add Delta Inverter VFD-EL (with Profibus card CMA-PD01) into some profibus network.

Probably you will need GDS file.

And the tutorial
Delta – Siemens comunication VFD-EL via CME-PD01 (Profibus)

Let us know If this information is important for you, and we’ll post the same for new inverters like C2000 or CP200.
Ah! and remeber our profibus slave module in case you need to add cost effective remote I/O

Announcement – WPLSoft v2.31

Welcome to the wizards again!

Just yesterday new version of WPLSoft v2.31 has been released on Delta website.
If you want to check the improvements, don´t hesitate to download the following Technical Announcement.
Technical Announcement WPLSoft V2.31

But personally the most important improvement is the reappearance of the wizards, missed on the last version WPLSoft 2.30.

Is available on the website and as always on our FTP
Delta Website WPLSoft V2.31
FTP DVP Software folder

Enjoy it!

Technical Announcement – PNP connection to Delta Servodrive

This is dedicated for European customers.
Mainly PNP is used exclusively in Europe, some machines in Middle East, but America and Asia and completely NPN.
That’s why in the first place our servo drive inputs are only compatible for NPN PLC output (like our Delta PLC’s).

But what happen If my customer is really used to work with his European brand PLC, but he wants to test our servo drives?
In this case we suggest the following PNP connection for ASDA-A2.

Furthermore, in the attached file you will find all the other suggested connections for the other servo drive series.
