Connect a maxon IDX70 drive with a ctrlX OS device

[ctrlXW-ChrisB]

This how-to describes how to connect an IDX70 drive from maxon with ctrlX CORE as a step-by-step guide.
It adresses customers using maxon drives as well as ctrlX OS devices, such as controls in their machines or installations.

Requirements 

Hardware

• maxon IDX70L EMT P ET 48V
• ctrlX CORE X3 with ctrlX OS version 1.20 (or higher) pre-installed

Software installed on ctrlX CORE X3

• PLC basic app (or higher/with add ons)
• EtherCAT Master app
• Motion app

Software installed on engineering PC

• Maxon EPOS Studio
• ctrlX I/O Engineering and PLC Engineering (parts of ctrlX WORKS)

For operation of ctrlX PLC, ctrlX EtherCAT Master and ctrlX Motion app an adequate software license is required!

Export of the ESI file for EtherCAT

1. Start EPOS Studio
2. Connect IDX Drive via USB with the EPOS Studio
3. Set up Your IDX via the Startup Wizard in EPOS Studio

6. Open the "Object Dictionary" tool.
7. Right-click on any line in the "Object Dictionary".
8. Select "Export ESI File".

Setup ctrlX I/O Engineering

Open the web-based engineering of the ctrlX CORE either via your network folder of Microsoft Windows, from ctrlX WORKS or directly by entering the IP in a web browser and login.

1. Open The “Home” tab and select “Configure EtherCAT”.
2. Add a new EtherCAT Master configuration.
3. Select the correct port for the EtherCAT Master at XF 50.
   
   Select the port for the EtherCAT Master
   
   
4. The EtherCAT Master will then be created. Next Step is to open the ctrlX I/O Engineering.
   
   Open ctrlX I/O Engineering
   
   
5. Via the Device Repository, the ESI file needed will be added to the system.

6. After clicking the Install Button, the ESI file created earlier must be selected. 
   If you do not have a specific ESI file created as described above, all standard ESI files will be installed with the EPOS Studio. The standard path for this example is:
   C:\Program Files (x86)\maxon motor ag\EPOS IDX\IDX\03 Configuration
   
   Install all maxon ESI files with the EPOS Studio
   
   
7. Now the maxon devices can be detected. With the selection of Scan for Devices, all known devices in the network will be shown.
   
   Select Scan for Devices
   
   
8. Click on the “insert all newly scanned devices”-button in order to copy all EtherCAT devices from the control to the project.
   
   Copy all EtherCAT devices from the control to the project
   
   
9. Click apply and OK to create the device in the I/O-Project.
   
   Create the device in the I/O-Project
   
   
10. Once the configuration is completed, click on the “download the fieldbus configuration” button.
    
    Download fieldbus configuration
    
    
11. After the fieldbus configuration is downloaded successfully to the ctrlX CORE, the EtherCAT status will be switched to “OP”. To validate this, you can click on the “EtherCAT” bar to see the current state of the EtherCAT Master and all connected slaves. The fieldbus configuration can now also be seen in the ctrlX CORE Datalayer.

Setup a ctrlX Motion

1. Add Axis Profile
   Add axis profile
   
   
2. Enter a name, select device via dropdown and select CANopen over Ethercat
   
   Add axis profile
   
   
3. Since the necessary Variables are not mapped yet, they have to be mapped manually
   
   Map Variables

4.  Map the variables
   Mappig of actual Position Variable

   Mapping of Statusword, Controlword and Target Position
   
   

5.  Go to Setting and selct Data layer

6. Go to axisprofile/profiles/IDX70L/scaling-information and change the Values to the ones below. For Resolution, enter the value you noted down early or look it up in your datasheet. 

   Edit scaling
   
   

7.  Add Motion axis and connect axis to the profile.

8.  Switch Motion into running Mode

   Activate running mode
