Position Loop Gain
Position Loop Gain has a direct effect on the response speed of Position Loop.
Under the condition that there is no vibration or noise from servo motor, increasing the Position Loop Gain
Value can enhance the response speed and hence reduce the positioning time.
Position Loop Feed-Forward Gain
Using Position Loop Feed-Forward Gain can enhance the response speed.
If the Feed-Forward Gain value is setting too high, overshooting could occur and cause the
INP (In Position)
output contact to switch ON and OFF repeatedly.
SO monitor Speed Curve and
INP (In Position Signal) at the same time then increase Feed-Forward Value
slowly.
If Position Loop Gain is too high, Feed-Forward function will be insignificant.
Quick Parameters for Gain adjustment
Quick Gain adjust parameters are available for setting manually.
The related Gain Adjust parameters are listed in the Quick-Parameter leaflet for convenient reference.
Quick adjust parameters once altered are saved and become effective
immediately,
without pressing the Enter-Key. The table below shows the Gain Adjust Quick-Parameters.
