3. Tuning Parameters
Function
Increasing this parameter value will reduce the position
error
after the command
becomes zero� Increase when the convergence of the position
error
at settling is not
good�
Parameter
115.0
Default: 50 [rad/s]
Setting range: 5–1,000
Remark
Select a value no higher than Position Control Mode: Control Gain 2 (116�0)�
Set a value smaller than the value of Control Gain 2 (116�0)�
Making a change to any of the following will also change other tuning parameters
(such as Control Gain 2) to the prearranged parameter set all at once�
• Control Gain Set （113�0）
• Inertia conditions （113�1）
• Control Level （114�0）
Tuning Tip
Increasing this parameter setting will improve the settling time in cases when increasing
the control gain set or control level does not resolve poor convergence of position
error
, or noise is too much that the control gain set or control level
cannot be
increased�
