(4) Auto tuning response level
The PA03 is related to the response of the whole servo system. As the response level setting is
increased, the traceability and settling time for a command decreases, but a too high response level
setting would generate vibration. Therefore, keep setting until the optimum response is obtained
within the range without vibration.
If the response level setting which user desired would cause machine resonance, the machine
resonance suppression filter (PB01, PB02, PB21, PB22) and the resonance suppression low-pass
filter (PB03) could be employed to suppress machine resonance. Suppressing machine resonance
may allow the response level setting to be higher.

For the response level setting, it is recommended to use the level value from low response to high
response gradually. It is probable to make resonance if the initial value is too high.
The applicable ratio of load inertia to motor shaft is a reference. The actual range would vary with
the different mechanical systems.
