7-3 Normal Mode Autotuning
Normal mode autotuning is used to estimate the load inertia of the machine.
Position data generated within the Servo Drive is used to operate the machine for the estimation,
thereby achieving greater accuracy in estimating the load inertia.
Normal mode autotuning can be used from the Parameter Unit or CX-Drive.
Setting the Parameters
1. Set the operating pattern.
Set the operating pattern using the Normal Mode Autotuning Operation Setting (Pn025).
