(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/load to motor mass 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. Executing gain switching while
the servo motor stops, You can change vibration frequency, resonance frequency, vibration
frequency damping, and resonance frequency damping.
