The recommended specification for potentiometers compatible across our range of drives ATV12, ATV212, ATV320, ATV340, ATV630 and ATV930 ( and the legacy ranges ATV15, ATV452, ATV16, ATV66, ATV18, ATV28, ATV58, ATV11, ATV31, ATV312, ATV21, ATV61 and ATV71) is 2.2k Ohms. It is possible to use a value between 2.2k Ohms to 10k Ohms in certain instances.
Schneider Electric can supply two potentiometers of the optimum value of 2.2k Ohms;
2.2k Ohms - 3 Watts - IP65 - 9.5 mm cut-out
For use in dry environments on a wall-mounted or floor-standing enclosure.
