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:
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!

HI DELTA
i have done almost all basic para metering and run procedures with CanOpen.
i would like to ask one question.
i am using “Operation command” in PDU to run VDF
and “Frequency Command” for VDF frequency.
which index register will be used to change the motor direction in PDU Maping.
thank you

Hello sir,
i m doing a project with 25 VDFs with 3 delta PLCs and 2 HMIs.
can i connect all devices with CANBuss? or should i connect only VDFs with Can-bus and rest of the devices with Ethernet?
please advice.
thank you

I use beckhoff PLC with delta VFD EC. documentation of VFD is very poor and a couldnt manage to control it. after importing ESD file i am having
input variables:
status Register
Velocity demand
output Register:
Control register
Required velocity
Can anybody tell me how to use control register of VFD E C.
Thanks

I tested the dvpcopm with a SA2 plc and ifd9503 with a ss2 as slave , everything works fine.After this I added a altivar31 drive on the can network , the eds file for v1.2 is included in the canopenbuilder2.02 but i had to use eds for v1.7 . I can use the drivecom parameters(index 6040 , 6041) but any other parameter gives me bus errors (E1).

Hello Bartek,
I remember that problem, in this case you need to put the COB-ID number manually depending on the node number.
But from CANopen Builder v2.02 available on the web, this problem is solved.
The Version used from my side is v2.03, but you can do exactly the same with V2.02

Everything looks ok but one thing was not showed. I made such connections and in earlier versions of CanOpen Builder there was a problem with EDS file and mapping PDO parameters. I see that this project was made on CanOpen Builder 2.03 which … is not available yet.
