POINT
As the initial value, "Adaptive vibration suppression control selection" is set to
"Disabled (_ 0 _ _)" in [Pr. 25].
When "Adaptive vibration suppression control selection" is set to "Enabled (_1_ _)"
in [Pr. 25] during servo-off, the adaptive filter II is executed after servo-on.
When "Adaptive vibration suppression control selection" is set to "Enabled (_1_ _)"
in [Pr. 25], the machine resonance frequency is reset by the vibration tough drive
function. When the machine resonance does not stop after the resetting, execute
the adaptive filter II again.
Before replacing a servo amplifier which uses this function with other equipment,
set "Adaptive vibration suppression control selection" to "Disabled (_ 0 _ _)" in [Pr.
25] and clear the filter properties of the adaptive filter II.
Name and function
For manufacturer setting
Low-pass filter selection
0: Available (Automatic adjustment)
1: Disabled
When available is selected, the filter in the zone expressed by the
following formula is automatically set.
For 1 kW or less
VG2 setting value × 10
2π × (1 + GD2 setting value × 0.1)
For 2 kW or more
VG2 setting value × 5
2π × (1 + GD2 setting value × 0.1)
Adaptive vibration suppression control selection
0: Disabled
1: Enabled
When the servo amplifier detects mechanical resonance with the
vibration tough drive function after the automatic filter setting of the
adaptive filter II is completed, reset the filters.
This is available with servo amplifiers with software version A9 or
later.
