Succesful Application: DVP20PM + DOPB-PS and G-Code download feature

Today, were going to talk about motion control.
There´s a PLC not released in many countries, but capable to manage up to 3 axis using step and direction control, is called DVP20PM or PM series.

20070817-20PM

This PLC needs special software called PMSoft, available on the web for free, as always.
This software a part from be able to program DVP20PM, it have the capability to work with G-Code files

PM-Soft Software

The G-Code files are a codified files that transform a Autocad file into a motion control trajectories, making the programming of motion control systems really easy.
Thanks to that codification, you can cut a difficult wood profile for example, designed previously using Autocad, and avoiding the hard PLC programming work to the engineer.

The problem that customer use to have with DVP20PM is when customer want to change the cutting profile of their product, because in that occasions, the Computer is needed, and not always our customer have a computer on the machine, isn’t it!

G-Code DVP20PM Download

Here, is where appears our new DOP-PS models, already available in EMEA region.
With this HMI´s your customer have the capability to change the G-Code profile only with one USB disk, following the next process:
1. Create Autocad File
2. Transform to G-Code and copy to USB disk
3. Connect the USB Disk to the DOPB-PS and download it to the 20PM
4. Run the program!

According to that, our HMI team prepares for us the complete following example where we´re going to cut an Scorpion picture profile into our 20PM.

You can download the HMI and PLC programs, and a nice pdf detailed explanation of how they create this application in our FTP Delta application guide folder

DVP20PM + DOPB-PS and G-Code download feature example

As you should understand this really simple kind of CNC tool could be applied to many kind of applications, from Wood cutting, plasma, or gluing, to stone grinding or even metal cutting!
Don´t hesitate to share your experiences with us.

And really soon same functionality to DVP10MC the future CANopen motion controller from Delta!

Motion Control: Pick & Place (2 axis interpolation)

One of the most typical applications once you have some interpolation device in your hands is Pick & Place.
The objectie of the application is move some object from one point to another one, and you can´t find one single company that didn´t need in some way one variable of this application.

Of course application have multiple variables, and the most easy one is with linear movements.
Simple movements Pick & Place

But later engineers think how to save time with that process to make their machines faster.
And the easy way is to interpolate both axis following a semicircle as below.
Two axis interpolation

Because of the popularity of Pick & Place, in Delta we have several devices able to work like that. Further more our ASDA-A2 servodrive is able to do it by his own, with no extra PLC or motion controller.

But today I would like to share how to do that application with one of our standard CPU´s and ASDA-B servodrive controlled trough Step & Direction.
So in this case you can use the same program to control Servo systems, Steppers or even inverters.
The CPU´s able to interpolate two axis nowadays in Delta are: DVP-SA2, DVP-SX2 and DVP-SV.

Regarding the application, you can found how to connect the hardware in the following old post
Motion Control: HMI – PLC – B series Servo (1 axis movements)

And Regarding the Software, the keypoint is the DCIMA instruction.
check the following program
Pick & Place Example

And If you are still not fully convinced to use our PLC´s for Pick & Place.
Here is some video example of our system working!
Is not exactly a pick & place application, but uses the same instruction.

And don´t hesitate to Let us know about your experiences with Pick & Place

Announcement: New connector ASD-IF-SC5020 for A2 servodrives series

Tired of soldering connectors?

How irritating it is to sold the DI/DO on A2 servodrive, just for testing, isn´t it?
So, take a look to that connector!

What do you think?

Check the details on the following new product announcement.
And ask for it to your local distributor!

ASDA-A2 and ASDA-B2 motor tuning procedure

As many of you should know, to tune a servo motor is not a piece of cake.
To have a good tune, you have to take care of the load, the inertia, the gearbox, etc..

To help you in this task, Delta provide different kind of tools.

1. ASDA-Sizing
This software is really useful to calculate the interta and the Torque needed of your system.
With this tool you can calculate the power of the motor needed and avoid bad experiences in customer’s hose

You can dowload it for free (as usual) on Delta’s web page.
But If you already installed ASDA Soft, check your computer, because probably it would be there.
ASDA-MSizing v1.04

2. Autotuning
Depending of the drive the ASDA-Soft have different autotuning tools.
On the video, we adjust (without load) some ASDA-B servodrive

On the other side, for the ASDA-A2 servodrives, our Service team, did the following PDF to help you in that task.
Simple TUning ASDA-A2&B2

Good tuning for everybody!

EDS Builder

Everytime you need to insert your devices inside some Devicenet or CanOpen network, the master would need some driver.
Those drivers are called EDS files.
That EDS file is different for every drive, and it may be configured depending of the data that we want to send to the master.

Delta have many Inverter and Servodrives models able to communicate trough CANOpen or Devicenet, because of that I would like to introduce you to a software tool to create that specific EDS files for each drive and application.

EDSBuilder V1.01, just released a month ago, we’ll be able to create the EDS file compatible with any brand CANOpen or Devicenet network.
Of course, Delta already have CANOpen master to controll them, but this is another history.

Software EDS Builder V1.01

To use this software, we will need the device to communicate, and some IFD6500 (USB-RS485 converter) to communicate with the device.

And once you have it, just follow the instruction of the following tutorial  “How to create EDS via EDSBuilder”
