- 156 -
(7) Stop time observer disable function
If the observer function is enabled, the machine may fluctuate and
become unstable when it stops. Such a fluctuation or unstable
operation can be prevented by disabling the observer function only in
the stop state.
(8) Setting parameters
<1> Function bit
#7 #6 #5 #4 #3 #2 #1 #0
1960 (FS15i)
MOVOBS
2018 (FS30i, 16i)
MOVOBS (#1) The function for disabling the observer in the stop state is:
0: Disabled
1: Enabled ← Set this value.
<2> Level at which the observer is determined as being disabled
1730 (FS15i)
Level at which the observer is determined as being disabled
2119 (FS30i, 16i)
[Unit of data] Detection unit
[Typical setting] 1 to 10
If the absolute value of the position error is less than the level at which
the observer is determined as being disabled, the observer function is
disabled.
NOTE
This parameter is also used for the stop
determination level of the function for changing the
proportional gain in the stop state.
(Usage)
Set the function bit and the level at which the observer is determined
as being disabled so that it is greater than the peak absolute value of
the oscillating position error.
