1.1 Adjustment function available to servo amplifier alone
Outline
Use this function to reduce settling time within the designated In-position range.
Use this function if machine resonance occurs when the response level in the auto tuning and manual
mode is increased.
Use this function to adjust the machine resonance suppression filter automatically.
When the load to motor inertia ratio of a machine is 10 times or more, use this function to more increase
the response level of the machine.
Use this function to reduce settling time as the vibration is being suppressed, if the vibration during setting
is large at high-speed positioning.
Use this function to suppress vibration easily, if the vibration during setting is large at high-speed
positioning.
Outline
Use this function if the performance of the quick tuning, one-touch tuning, and auto tuning is not
satisfactory.
Use this function for:
1) Reducing the stop settling time
2) Increasing the gain during servo-lock while suppressing vibration sound during rotation
3) When load fluctuation is large
Use this function to improve path accuracy by decreasing droop pulses at the constant speed.
Use this function to decrease the overshoot.
Use this function to suppress vibration at a servo motor stop.
Use this function for freefall prevention on vertical axis at servo-on.
Use this function to suppress overshoot in path control.
Use this function to suppress quadrant projections at speed switching in path control.
