Issue:
A Suffix meaning on an ATV31.

Product Line:
Altivar 31 ATV31

Environment:
All

Cause:
Drive part number omits the A suffix.

Resolution:
The ATV***31A has the start/stop button, run button, and a potentiometer on the front of the drive. The ATV***31 without the "A" at the end of the part number does not have the start/stop, run, and potentiometer on the front of the drive.
