5. PARAMETERS
No. Symbol
PB11 VDC Speed differential compensation
This is used to set the differential compensation.
To enable the parameter, select "Continuous PID control enabled (_ _ 3 _)" of "PI-PID
switching control selection" in [Pr. PB24].
PB12 OVA Overshoot amount compensation
This is used to set a viscous friction torque or thrust to rated torque in percentage unit at servo
motor rated speed or linear servo motor rated speed.
When the response level is low or when the torque/thrust is limited, the efficiency of the
parameter may be lower.
PB13 NH1 Machine resonance suppression filter 1
Set the notch frequency of the machine resonance suppression filter 1.
When you select "Automatic setting (_ _ _ 1)" of "Filter tuning mode selection" in [Pr. PB01],
this parameter will be adjusted automatically.
When you select "Manual setting (_ _ _ 2)" of "Filter tuning mode selection" in [Pr. PB01], the
setting value will be enabled.
PB14 NHQ1 Notch shape selection 1
Set the shape of the machine resonance suppression filter 1.
When you select "Automatic setting (_ _ _ 1)" of "Filter tuning mode selection" in [Pr. PB01],
this parameter will be adjusted automatically.
Set manually for the manual setting.
