### REFRESH

is a command that is used when tuning the drive for COMPMODE 3. With the Advanced Pole Placement algorithm utilized in the drive, the interaction of the variables is too dramatic to allow variables to be changed one by one. Therefore, as pole placement algorithm vector variables (VD, VF, VH, and VR) are entered, the new values are buffered without changing the actual values used by the control loops.

Once all desired new values have been entered, the operator enters a REFRESH command, and all vector variables are written to the control loops simultaneously.
