7. SPECIAL ADJUSTMENT FUNCTIONS
7 - 23
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.

PB48/PB49 Enabling the filter disables the shaft
resonance suppression filter.
The shaft resonance suppression filter is
enabled for the initial setting.
Machine resonance
suppression filter 5
PB50/PB51 The setting of this filter is disabled while
you use the robust filter.
The robust filter is disabled for the initial
setting.

(During tough drive)
[Pr. PF23 Vibration tough drive - Oscillation detection level]
Detects the machine resonance and reconfigures the filter automatically.
During tough drive (MTTR) is not turned on in the vibration tough drive function.
