Not using the PC Loader
There are two checking methods.
If measurement of the vibration frequency can be made with a laser displacement gauge or similar,
adopt method 1). In other cases, adopt method 2).
1) Measure the vibration of the arm tip with a laser displacement gauge or similar.

2) Starting at 300.0 Hz (maximum setting), decrease the reference values of parameters
PA1_78, 80, 82 and 84 gradually while visually checking vibration, to find the best value.
