17. APPLICATION OF FUNCTIONS
17 - 58
The following shows the function block diagram of the vibration tough drive function.
The function detects machine resonance frequency and compares it with [Pr. PB13] and [Pr. PB15], and
reset a machine resonance frequency of a parameter whose set value is closer.

suppression filter 1
PB01/PB13/PB14
The filter can be set automatically with
"Filter tuning mode selection" in [Pr.
PB01].
PB13
Machine resonance
suppression filter 2
PB15/PB16
PB15
Machine resonance
suppression filter 3
PX17/PX18
Machine resonance
suppression filter 4
PX19/PX20
Enabling the machine resonance
suppression filter 4 disables the shaft
resonance suppression filter.
Using the shaft resonance suppression
filter is recommended because it is
adjusted properly depending on the
usage situation.
The shaft resonance suppression filter is
enabled for the initial setting.
Machine resonance
suppression filter 5
PX21/PX22
Enabling the robust filter disables the
machine resonance suppression filter 5.
The robust filter is disabled for the initial
setting.
