No. Name and function
PB12 This parameter is not used. Do not change the value.
PB13 Machine resonance suppression filter 1
Set the notch frequency of the machine resonance
suppression filter 1.
When the [Pr. PB01] setting is "_ _ _ 0", the setting of
this parameter is ignored.
If a value exceeding "3000" is set for this parameter, it is
automatically rewritten as "3000".
PB14 Notch shape selection 1
Select the shape of the machine resonance suppression
filter 1.

When the [Pr. PB01] setting is "_ _ _ 0" , the setting of
this parameter is ignored.
PB15 Machine resonance suppression filter 2
Set the notch frequency of the machine resonance
suppression filter 2.
Set [Pr. PB16] (notch shape selection 2) to "_ _ _ 1" to
make this parameter valid.
If a value exceeding "3000" is set for this parameter, it is
automatically rewritten as "3000".

value
PB12 Overshoot amount compensation
Set a dynamic friction torque to rated torque in
percentage unit at servo motor rated speed.
When the response level is low or when the torque is
limited, the efficiency of the parameter may be lower.
4500 PB13 Machine resonance suppression filter 1
Set the notch frequency of the machine resonance
suppression filter 1.
When "Filter tuning mode selection" is set to "Automatic
setting (_ _ _ 1)" in [Pr. PB01], this parameter will be
adjusted automatically by adaptive tuning.
When "Filter tuning mode selection" is set to "Manual
setting (_ _ _ 2)" in [Pr. PB01], the setting value will be
enabled.
0000h PB14 Notch shape selection 1
Set the shape of the machine resonance suppression
filter 1.
When "Filter tuning mode selection" is set to "Automatic
setting (_ _ _ 1)" in [Pr. PB01], this parameter will be
adjusted automatically by adaptive tuning.
To enable the setting value, select the manual setting.
