Programming tool
MR Configurator2 is not available.
Use FR-DU07/FR-PU07 or FR Configurator.
MR Configurator2 is available.
(Note-1): Confirm the specifications of FR-A700 series for details.
(Note-2): Parameters set in FR-A700 series are not controlled by Simple Motion module. Therefore, the operation is the same as when the
servo parameter "Rotation direction selection/travel direction selection (PA14)" is set as below during amplifier-less operation
mode.
