Successful Application: 11 Axis Cutting / profiling machine

Another successful application from our Netherlands distributor Innomotion.

This time is a Woodcutting / Profiling machine with 11 axis control!

Kast

As you can see on the picture our partners use 7 VFD-E drives for transportation and high speed spindle, and 4 servodrives ASDA-A2 400W for the cutting/profiling.
Everything controlled by central CPU with Master CANopen module (DVPCOPM-SL).

Via the PC Cad drawings are imported to the Machine and machine settings are executed. The PLC is controlling all the I/O and servo’s for the motion.
In this machine the wooden boards for the stairs are cut to length , width and angle on front and end of the board. The PC software is written in Labview.

I hope you like it!
And with some luck, you can use it as inspiration for your next project!

Succsessful Application: Galvanizing production line on metal industry

Another Delta successful application!

Picture2

This time, the problem comes because of the big number of drives needed for the application.
Up to 68 Slaves to be controlled by a PLC, and even in Modus the theoretic limit is 128 nodes, the ones who are really in the field should know than more than 32 nodes means big troubles.

According to this, we recommend to our customer to use CANOpen in two different CANOpen Networks of 34 slaves each.
See the below picture with the network configuration

Just let you know that it wasn’t easy, but is working, thanks for the great technicians of our Turkish distributor FastLTD.

Feel free to download the presentation with full explanation of the application.

CANOpen Communication: DVPCOPM-SL with VFD-EC

Why Can Open?

Modbus is strong an with a long and successful story of applications, but when interpolation is needed, you should need something else..
Is strong, easy to use, and more important fully compatible with many different brand devices on the market.

Because of that we want to start a new Can Open Category with simple applications, easy to work on.
In the near future we will keep adding Can Open examples with all our new compatible Can Open devices (ASDA-A2, C2000, etc…) but for start our cost effective CANOpen drive VFD-EC will work.
Let´s start with the Hardware.

Hardware Configuration:

1. DVP-SX2 + DVPCOPM-SL (CANOpen Master)
2. VFD-EC (CANOpen Embedded Slave)
3. TAP-CN03 (CANOpen Splitter with terminal resistor)
4. TAP-CB03 (CANOpen Cable)

Be aware on the following advices:
– Use CANOpen wirings, Ethernet cables have the same pin-out, and they will work on short distances, but it can give you problems due they don´t have same internal impedance.
– Remember to turn on the terminal resistor switch of TAP-CN03! If you don´t want to use it, remember to put 120 Ohm terminal resistor.
– No need to supply V+ and V- connections for short distances, for long ones is recommended.

So at last, you may have something similar to this:

VFD-EC Configuration:

P0.02 -> 9 Reset fatory default values

P2.00 -> 5 CANopen of First master frequency command
P2.01 -> 5 CANOpen of forst operation command
P4.08 -> 23 multi-function input terminal (MI6) as Emergency STOP (link MI6 and DCM to work)
P9.20 -> 2 CANopen Station Address
P9.21 -> 0 CANOpen Baudrate 1Mbps
P9.24 -> 1 Adapt DS402 protocol

CANOpen Builder Configuration:

Full screen recommended

As you can see in the video, once you link on the EDS files the inverter parameters with the PLC registers, you just have to work with them as local registers in the PLC.
The PDO frames are going to be sended automatically in a continuous matter, so every change will be automatically updated in the other device.

HMI and PLC Program:
And after that, you only need to download the PLC and HMI programs.
You will find it in the following link.
The HMI and PLC are connected trough RS232 (DVPACAB2030), but you can change it with no problem.

If it´s your first step with CANopen, test it in your lab, and let us know your experience.
Enjoy!

Announcement: DVPCOPM-SL CANOpen Comunication manual
