I perform auto-tuning on the UT, but the auto-tuning parameters (AT) do not appear.

Check the following.

  1. Is the control type (CNT) ON/OFF, or 2 position 2 stage control?--> If so, change it to something other than that.
  2. Is the STOP lamp lit? --> Start operation (RUN).
  3. Is the MAN lamp lit? --> Set it to AUTO.
