No. Name and function
PB14 Notch shape selection 1
Used to selection the machine resonance
suppression filter 1.
Setting [Pr. PB01] (Adaptive tuning mode (Adaptive
filter II)) to "_ _ _1" automatically changes this
parameter.
When the [Pr. PB01] setting is "_ _ _0", the setting
of this parameter is ignored.
