DST, Parameter P2-26 External Anti-Interference Gain
This parameter is used to enhance the anti-interference capability and reduce the occurrence of
overshoot. The default setting is 0 (Disabled). It is not recommended to use it in manual mode
only when performing a few tuning on the value gotten through P2-32 AutoMode (PDFF) (setting
value is 5, mode 5) automatically (The setting value of P2-26 will change to the value that
measured in mode 5 (AutoMode (PDFF)) when switching mode 5 ((AutoMode (PDFF)) to mode 0
(Manual mode)).
PFG, Parameter P2-02 Position Feed Forward Gain
This parameter is used to reduce position error and shorten the positioning settling time. However,
if the setting value is over high, it may easily lead to the overshoot of machinery system. If the
value of electronic gear ratio (1-44/1-45) is over than 10, the machinery system may also easily
generate vibration or noise.
