This appnote shows step by step how to configure realtime operation with TwinCAT3 and ADI Trinamic EtherCAT modules. For example the TMCM-6213 is a six axes controller/driver module for 2-phase bipolar stepper.
It supports EtherCAT interface with CoE CiA-402 Drive Profile for all axis. General usage of TwinCAT is not explained.
Preparation
It is recommended to update the ADI Trinamic module:
Firmware
EEPROM
ESI file (.xml)
ADI Trinamic module firmware should be at least v1.09. Example for files notation as follows:
TMCM-6213.xml
TMCM-6213_CoE_V109.bin
TMCM-6213_CoE_V109.hex
The files can be downloaded from the module page: https://www.trinamic.com/products/modules/details/tmcm-6213/
Create a new TwinCAT XAE project
Assign dedicated processor core to TwinCAT
Assignment of processor core needs to be done only once!
The processor core will be used for realtime motion NC_Task
Read from Target Figure 1: Available CPU (Windows/Isolated) = 4/0 → no processor core is assigned to TwinCAT yet
Set on target Assign processor core to TwinCAT:
After restart check the Task Manager -> Resource Monitor
The core assignment is permanent. In order to unassign processor core again repeat step 2. Using the Set on targe dialog and set Available (Windows/Isolated): 4/0
For the next steps in this app note, the configuration should be set to Available CPUs (Windows/Isolated): 3/1
Select assigned processor core
Open TwinCAT Project.
Project → System → Real-Time → Settings Tab
Choose Isolated CPU core.
Deactivate Windows CPU core.
Thus the windows core is reserved for TwinCAT real-time operations. In the next step the real-time
operation will be activated.
Activate Configuration (Motion Task)
Activate configuration.
Enter the License code which is generated.
Execute win8settick.bat as administrator if the following Error shows up. This is a TwinCat specific Error.
If the configuration is active, the green logo shows up in the bottom right corner.
Use Jogging Mode
Axis 1 is driven in Jogging Mode in this section.
Configure Monitoring
Axis 1 → Parameter → Monitoring → Set Every Value to False (since not provided by the module)
Confirm every value by clicking on Download.
Set axis 1 to CSP mode. Write 8 to Axis0 Modes of Operation 1
Modes of Operation as SDO (Firmware v207) Modes of Operation as PDO in (Firmware v208)
Enable Controller and Feed Fw/Bw
Motion → Axes → Axis X → Tab Online → Enabling → Set → All
Use Jog Control Buttons to move the axis X.
