About this task

Verify that the VFD68 is in PU mode with no jumper between SD and STF (Figure 1).


  1. Verify that the jumper above terminal SC (Figure 1) is set to SINK.
  2. Verify that the AI2 mode switch to the left of terminal A (Figure 1) is set to V for applications with 0–5 V or 0–10 V voltage input or set to I for applications with 4–20 mA current input.
  3. Exit the PU (manual operation) mode by pressing PU/EXT until the EXT LED is highlighted, then use a jumper to connect SD to STF.


The VFD68 is now commissioned, is in the external operation mode, and is ready to run the motor using the analog inputs.
