(a) [Pr. PB06] to [Pr. PB10]
These parameters are the same as in ordinary manual adjustment. Gain switching allows the values
of load to motor inertia ratio, position loop gain, speed loop gain, and speed integral compensation to
be switched.
(b) [Pr.PB19] to [Pr.PB22]/[Pr.PB52] to [Pr.PB55]
These parameters are the same as in ordinary manual adjustment. You can switch the vibration
frequency, resonance frequency, vibration frequency damping, and resonance frequency damping
by switching gain during motor stop.
