instability of the entire system and increase the phase lag. The recommended setting value
is to follow below calculation:
Position feed-forward gain (FFC)
This parameter can reduce the position error and shorten the settling time. However, if you
set the value too high, it might cause overshoot in positioning when sudden acceleration or
deceleration occurs. A large E-Gear ratio setting might cause noise as well.
Speed feed-forward gain (VFG)
This parameter can shorten the speed command following time. However, if you set the value
too large, it might cause overshoot when sudden acceleration or deceleration occurs.
5.3.5 Interpolation mode
This mode is used to control two or more axis servo system, the controller gain parameter are
still in the automatic tuning function, the main content is as follows:
Interpolation mode 1: only the position gain value (PB07) can be set manually. The remaining
gain value (PB06, PB08, PB09) are automatically adjusted with PA03 settings.
Interpolation mode 2: the position gain (PB07) and load inertia ratio (PB06) can be adjusted
manually, and the other gain value (PB08, PB09) are automatically adjusted with the setting
of PA03.
