Operation
Note 2. A torque will be generated that accelerates the Servomotor in the forward direction if torque

H Functions
• This function shortens positioning time by adding the REF (speed command input) value to the speed
• Normally, the differential value for the position command (pulse train command) is generated in the
• If the feed-forward amount (REF voltage) is too large, an overshoot may occur, so adjust Pn300

feed-forward is applied with a positive (+) voltage. Be sure that the polarity is correct because
errors such as reverse Servomotor rotation or oscillation will occur if the feed-forward is ap-
plied with a polarity opposing the acceleration direction.
