Limiting Motor Rotation Direction And Output Phase Rotation - YASKAWA Varispeed E7 Instruction Manual And Parameter Description

Limiting Motor Rotation Direction and Output Phase Rotation

If the motor reverse rotation is prohibited, a reverse run command will not be accepted, even if it is input. Use
this setting for applications in which reverse motor rotation can cause problems (e.g., fans, pumps, etc.)
It is also possible to change the output phase order by changing b1-04 to 2 or 3. This much easier and faster
than changing the wiring if the motor rotational direction is wrong.
