Delta Electronics participated in Middle East Electricity show in Dubai

Delta Electronics has showed its products and solutions in the MEE exhibition held in Dubai (1-3 March).

Various products were demonstrated in the booth, including PLCs, HMIs, Drives, Servo and Delta Multi-Pump Solution (DMPS).

Visitors from all around the middle east were present, good connections were made and costumers showed lots of interest in our products.

Due to the fact that oil prices are going down, and most of the projects in the Gulf area are oil and gas related projects, lots of costumers moved their attention to Delta as an economic alternative to other brands.

Some pictures from the show:

See you soon in Hannover Messe, April.

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.

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, isnĀ“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.

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.

Good tuning for everybody!

PLC Link (PLC to VFD)

PLC-Link is not only a tool to exchange data between PLC’s.
With PLC-link you can also share memory space with a servo, inverter, temperature controller, etc…
In this case I would show you the procedure to do it with VFD-E series drive.

The advantage of this method agains the “sending frames one” is that you don’t need to program and trigger one frame for every value read or write to the slave.
With this method, you only have to configurate the communication, and you will have any Slave value in your master buffers.
follow the next steps:

1. Hardware
use exactly the same advices as the PLC-VFD communication post.

2. Decide the protocol to be used.
And write it on a post it in front of you. In this case we use protocol Modbus ASCII, 9600 baud,7,Even,1

3. Inverter configuration (almost same as PLC-VFD communcation post)
The important think on this step is get ready the inverter to receive orders from RS485 interface, so depending the inverter the values are going to be different. In this example I use VFD-E.
Check the parameters If you are going to use another inverter.

2.00 = 3
Source of First Master Frequency Command
3: RS-485 (RJ-45) communication

2.01 = 3
Source of First Operation Command
3: RS-485 (RJ-45) communication. Keypad STOP/RESET enabled.

9.00 = 2
Communication Address
in my example 2

9.01 = 1
Transmission Speed
3: Baud rate 9600bps

9.04 = 1
Communication Protocol
0: 7,E,1 (Modbus, ASCII)

4. PLC Software
In this case I recommend to have the manual opened, because basically is a matter to configure the PLC-Link special registers properly.

D1399:ID address of the first slave
D1434:Number of consecutive registers to be Read (by the master)
D1355:First register direction of the slave to be Read (H2102 = Frequency command)
D1450: Number of consecutive registers to be Write (by the master)
D1415: First register direction of the slave to be Write (H2001 = Frequency command)
D1480:Readed values Master Buffer (Slave 1)
D1496:Writed values Master Buffer (Slave 1)

To find what register I need to edit in each case, look in the manual for any of those registers, and look for the proper one.

And Check the following program and test it.
PLC Link COM2 (PLC – VFD)

I’m pretty sure that system will save you a lot of time and efforts.

Announcement: ASDA-A2 three-phase 400Vac

I know… The announcement comes a little late, because probably some of you already have some of those devices in your Labs and/or Office.

But before wait for this device for such a looong time, we’re glad to announce it, even If it’s late!

You can download the official announcement in the link below, but basically those are the features of that 400 Vac A2 drives:

1. Broad power range available from 750W to 7.5kW.
2. Input power supply of all ASDA-A2 400V series servo drives is AC 400V (380V~480V), 3-phase.
3. An incremental 20-bit (1280000 p/rev) optical encoder is equipped.
4. The motor inertia is divided into three types: Low inertia (J), Medium inertia (K) and
Medium-High inertia (L). There are 80mm, 130mm and 180mm three kinds of frame
sizes are available. The motor speed is from 1500 r/min to 5000 r/min and the torque
output is from 2.39 N-m to 119.36 N-m.
5. Built-in flexible position register control mode (PR mode) is offered. 35 kinds of homing
modes and 64 internal memorized position settings are available.
