Damping compensation gain Kc (ABPGL)
2036
−
Set this parameter for the main axis only.
[Valid data range] 0 to 32767
[Setting method] Kc × 32768 (0 ≤ Kc < 0.5)
A function bit is not supported for the damping compensation function;
the damping compensation function is enabled at all times. When 0 is
set in this parameter, the damping compensation function is ineffective.

Damping compensation phase coefficient α (ABPHL)
2036
−
Set this parameter for the sub-axis only.
[Valid data range] 51 to 512
[Setting method] α × 512 (0.1 ≤ α ≤ 1.0)
When 0 is set in this parameter, this setting is internally handled as 512
(α = 1), When α = 1, phase compensation is not performed. Instead, the
set value is output to Kc as is.

(Example of adjustment) The speeds of the motors are checked using the check board (when the
motors rotate in the same direction).
This function may be useful when the oscillation frequencies (several
Hz to 30 or 40 Hz) are the same, and the phases are opposite as shown
below.
NOTE
1 When the directions of rotation of the main motor and
sub-motor are different, the phase relationship is
reversed.
2 When the phase difference is not 180°, the phase
coefficient α must be adjusted. Start with 512, then
decrease the value gradually.
