7. SPECIAL ADJUSTMENT FUNCTIONS
(c) [Pr. PB29 Load to motor inertia ratio after gain switching]
Set the load to motor inertia ratio after gain switching. If the load to motor inertia ratio does not
change, set it to the same value as [Pr. PB06 Load to motor inertia ratio].
(d) [Pr. PB30 Position loop gain after gain switching], [Pr. PB31 Speed loop gain after gain switching],
and [Pr. PB32 Speed integral compensation after gain switching]
Set the values of after switching position loop gain, speed loop gain and speed integral
compensation.
(e) Vibration suppression control after gain switching ([Pr. PB33] to [Pr. PB36]/[Pr. PB56] to [Pr. PB59]),
and [Pr. PB60 Model loop gain after gain switching]
The gain switching vibration suppression control and model loop gain are used only with input device
(CDP) on/off.
You can switch the vibration frequency, resonance frequency, vibration frequency damping,
resonance frequency damping, and model loop gain of the vibration suppression control 1 and
vibration suppression control 2.
