ID264 (P2.105) - AutoTuningBandwidth Parameter
This parameter is used to adjust the system bandwidth in conjunction with
autotuning. If this value is larger than the default response of 11, the
bandwidth after autotuning is higher, this higher bandwidth might be
problematic for your load, causing machine resonances or even instability. If
this value is smaller, the bandwidth after autotuning is lower, and the system
response is lower.

ID265 (P2.106) - AutoTuningOvershoot Parameter
This parameter is used to adjust the maximum allowable overshoot when
autotuning. The overshoot range is set according to the user or machine. If this
value is larger, the maximum overshoot that is allowed by autotuning is
greater, and the response is faster. If this value is smaller, the maximum
overshoot that is allowed by autotuning is smaller, but the response is slower.

Autotuning via the Drive Panel
See Figure 87 for an overview of autotuning via the drive panel. Make sure that
the emergency stop and the positive and negative limit works properly before
you start to tune the system.
