Can the ATV61 or ATV71 drive save the last speed reference when using the external knob for speed control on the HMI?

Issue:
Will the ATV61 drive save the last speed reference when using the external knob for speed control on the HMI?

Product Line:
Altivar ATV61 and ATV71 with VW3A1101 HMI

Environment:
All

Cause:
Knob on remote HMI is a digital signal reference its not saved if you power cycled the drive.  Drive will start back at low speed or 0 hz.

Resolution:
If you need to maintain the speed reference after you power down you may need to add a remote mounted POT to AI1, com and +10vdc as an option.
The HMI Reference if used will go back to 0 or LSP if cycled power to the drive. Can set LSP to desired setting. Also, there is a Reference saved parameter but it applies only to +/- Speed it does not apply to the HMI reference. .
