7. SPECIAL ADJUSTMENT FUNCTIONS
7 - 24
The following shows the function block diagram of the vibration tough drive function.
The function detects machine resonance frequency and compare 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

PB15/PB16
PB15
Machine resonance
suppression filter 3
PB46/PB47
Machine resonance
suppression filter 4
PB48/PB49
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
PB50/PB51
When the robust filter is used, machine
resonance suppression filter 5 will be
disabled regardless of the setting.
The robust filter is disabled for the initial
setting.
