 KVI, Parameter P2-06 Speed Integral Compensation
If the setting value of KVI is higher, the capability of decreasing the speed control
deviation is better. However, if the setting value is over high, it may easily result
in the vibration of machinery system. The recommended setting value is as
follows:
 NLP, Parameter P2-25 Low-pass Filter Time Constant of Resonance
Suppression
When the value of (J_load / J_motor) is high, the responsiveness of speed loop
may decrease. At this time, the users can increase the setting value of KVP (P2-
04) to keep the responsiveness of speed loop. However, when increasing the
setting value of KVP (P2-04), it may easily result in the vibration of machinery
system. Please use this parameter to suppress or eliminate the noise of
resonance. If the setting value of NLP is higher, the capability of improving the
noise of resonance is better. However, if the setting value is over high, it may
easily lead to the instability of speed loop and overshoot of machinery system.
The recommended setting value is as follows:
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.
