SED2 VFD Startup, Operation, and Maintenance Manual

Direction of Motor Rotation

To change the direction of motor rotation, cross-connect two of the output

conductors on the SED2 (Figure 25). This is the desired method for

changing rotation.

NOTE: The Reverse Output Phase Sequence parameter (P1820) can

also reverse the direction of rotation. However, if the SED2 is

reset to factory defaults, P1820 is reset to OFF.
