(a) Setting parameters related to disturbance input
Parameters related to the disturbance input function are set for the
sub-axis.
(About the disturbance input function)
The disturbance input function applies vibration to an axis by
inputting a sine wave disturbance to the torque command. In the
adjustment of tandem disturbance elimination control, this function is
used for the sub-axis to observe the interference status between the
axes when vibration is applied to the sub-axis.
For the sub-axis, set parameters related to the disturbance input
function.

DSTIN DSTTAN DSTWAV
2270(FS30i,16i)
DSTIN(#7) Disturbance input
0: Stop
1: Start (Disturbance input starts on the rising edge from 0 to 1.)
DSTTAN(#6) Set 0.
DSTWAV(#5) Set 0.
2739(FS15i)
Disturbance input gain
2326(FS30i,16i)
[Setting value] 500
(*) Set the amplitude of the applied vibration (torque). (Value 7282
is equivalent to the maximum current of the amplifier.)
First, set about 500 to apply vibration to the machine so that light
sound is generated. If it is difficult to observe the vibration status,
increase the parameter value gradually.
2740(FS15i)
Disturbance input function: Start frequency (Hz)
2327(FS30i,16i)
[Setting value] 0
(*) If 0 is set, the default (10 Hz) is assumed to be the vibration start
frequency.
2741(FS15i)
Disturbance input end frequency
2328(FS30i,16i)
[Setting value] 0
(*) If 0 is set, the default (200 Hz) is assumed to be the vibration end
frequency.
2742(FS15i)
Number of disturbance input measurement points
2329(FS30i,16i)
[Setting value] 0
(*) If 0 is set, the default (3) is assumed as the number of disturbance
input measurement points.
