H Parameters Requiring Settings
Note 1. When not using the bias function, set Pn107 to 0.
Note 2. If the bias rotational speed is set too high, it will cause Servomotor operation to be unstable.
H Setting Procedure
• Complete the gain adjustment before adjusting the bias.
• Increase the Pn107 (bias rotational speed) setting until positioning time is minimal. At this point, if
• If the overshoot is too large, increase Pn108 (bias addition band) to reduce it.

Advanced Adjustment Functions
The optimum setting depends on the load, the gain, and the bias addition band, so adjust the
setting while observing the Servomotor response. (Begin with a bias setting of Pn107 = 0, and
gradually increase it.)
