4-4 Characteristics improvement
4-4-4 Improvement of characteristics during acceleration/deceleration
<SHG control>
Because SHG control has a smoother response during acceleration/deceleration than conventional
position controls, the acceleration/deceleration torque (current FB) has more ideal output characteristics
(A constant torque is output during acceleration/deceleration.) The peak torque is kept low by the same
acceleration/deceleration time constant, enabling the time constant to be shortened.
Refer to item "(3) SHG control" in section "4-2-3 Position loop gain" for details on setting SHG control.
