Technosoft drives can handle different types of external reference signals: analog, pulse & direction or quadrature encoder.

The following steps describe how to configure a Technosoft drive to read the Pulse & Direction inputs as the external source for the position reference:

  1. Create a new project/setup based on your drive, motor and feedback type. If you only commission the drive with EasySetUp, then go to step 3.
  2. Select Setup from the project tree and press the View/Modify button.
  3. Follow the Guideline Assistant instructions to complete the motor and drive setup
  4. In the Drive Setup dialog, press the Setup button to open the External Reference Setup dialog
  5. Select the type of reference as Digital, then choose the source as Pulse & Direction
  6. Set the gear ratio between the master (pulse & direction signals) and the slave (drive/motor). A negative value for the slave will cause it to move in the opposite direction.
  7. In order to avoid motor mechanical shocks when the slave is connected “on the fly”, with the master moving, you can “Limit maximum acceleration”.
  8. Close the External Reference Setup dialog. If you use EasyMotion Studio to program the drive, then go to step 10.
  9. Check the Automatically activated after Power On option
  10. Press OK to close the Drive Setup dialog
  11. Press the Download to Drive/Motor button to download the setup data to the drive’s non volatile memory. If you use EasyMotion Studio to program the drive, then go to step 13
  12. Reset the drive to activate the setup. At this point, the drive will read the Pulse & Direction inputs as an external reference when it is powered on.
  13. Select Motion from the project tree.
  14. Press the Motion External button to open the programming dialog for external motion modes
  15. Choose Digital and press OK to generate the TML code.
  16. Download and execute the TML program.

The External Reference motion can be inserted from the motion branch. For details, please see the picture below:
