0 Function not used.
1 REF used as feed-forward input
• Set the REF function (speed command input) for position control.
• Select 1 to input the REF voltage speed feed-forward input, and add the speed equivalent to the speed
REF voltage to the speed loop command. This can shorten positioning time.
• You can change the REF voltage scale using Pn300 (speed control scale). (Default setting: 10 V/rated
rotations.)
• If using an OMRON Positioning Unit (pulse train output type), set this parameter to 0 (function not
used).
Note Refer to 4-8-4 Speed Feed-forward Function for details.
