H Parameters Requiring Settings
Note When not using the feed-forward function, set Pn10A to 0.
H Setting Procedure
• Finish adjusting the gain before adjusting the feed-forward.
• Increase the Pn109 (feed-forward amount) setting until positioning time is minimal. At this point, if
• If the overshoot is too large, increase Pn10A (feed-forward command filter) to reduce the it.

H Functions
• The torque feed-forward function reduces the acceleration time by adding the value of TREF (torque
• Normally a differential value is generated in the controller and this value is input to TREF.
• Overshooting will occur if the feed-forward amount (the voltage input to TREF) is too high, so adjust
