Bottom suppression function
When the input fluctuation by external disturbance is detected, the amount of FF
(Feedforward) is added to the output value to suppress the Bottom.
[Setting items]
FF amount: This can also be obtained automatically by Amount of FF which is
added to detect external disturbance and Learning function
FF amount learning: FF amount can be calculated from external disturbance when
detection of external disturb
ance is executed after selection of “Learn.” When
setting is completed, the value will automatically return to “0: No learning.”
Bottom suppression function: Used to activate/deactivate the Bottom suppression
function as well as a trigger function. There are two types of triggers; when the
Determination point of external disturbance (FF amount is added by the level) is
exceeded and Forced addition off FF amount. Trigger signal can be input through
communication in the case of Forced addition of FF amount.
