(c) [Pr. PB29 Load to motor inertia ratio/load to motor mass ratio after gain switching]
Set the load to motor inertia ratio or load to motor mass 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/load to
motor mass 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 gain switching model loop gain are used only
with control command from the controller.
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.
