29: Auto gain setting at positioning (position)
● Function
To get short period for positioning, the function automatically makes speed loop gain higher when a
deviation pulse number becomes small.
For the reason that the speed loop gain is proportionate to deviation pulse number, a positioning speed
at small error pulse number becomes comparatively low. In the case, the responsibility for the
positioning may be improved by the higher speed loop gain.
If the speed loop gain registered in [parameter] →[01: Speed loop proportional gain] is higher than the
automatic gain, the registered gain has priority.
0: without auto gain setting at positioning
1: with auto gain setting at positioning

(The power must be turned on again after setting a change.) (speed)
● Function
This function sets the motor’s rotation speed when the input command voltage is 10 V.
The relation between the input voltage and motor rotation speed is determined by the speed command
input factor in the following formula.
Motor rotation speed = Input command voltage ×
Torque command input factor

Note: The power must be turned on again after setting a change. The previous value is effective until
you turn on the power again.
Note: Motor rotation speed = Actuator rotation speed × reduction ratio
* The setting value varies depending on the model of the actuator.
