[Pr. Pb10_Speed Integral Compensation (Vic)]; [Pr. Pb11_Speed Differential Compensation (Vdc)]; [Pr. Pb12_Overshoot Amount Compensation (Ova)]; [Pr. Pb13_Machine Resonance Suppression Filter 1 (Nh1)] - Mitsubishi Electric MELSERVO-J5 MR-J5-G Series User Manual

[Pr. PB10_Speed integral compensation (VIC)]

Initial value
33.7 [ms]
Set the integral time constant of the speed loop.
Decreasing the setting value will improve the responsiveness, but will be liable to generate vibration and noise.
The setting of this servo parameter will be automatic or manual depending on the setting of [Pr. PA08.0 Gain adjustment
mode selection]. Refer to the following for details.
Page 27 [Pr. PB08_Position control gain (PG2)]

[Pr. PB11_Speed differential compensation (VDC)]

Initial value
980
Set the differential compensation.
The enabling conditions vary depending on the setting value in [Pr. PB24.1 PI-PID switching control selection].
[Pr. PB24.1]
"0" (Switching is enabled by PID switching signal (C_PC) from controller and the input
device (PC))
"3" (Continuous PID control enabled)

[Pr. PB12_Overshoot amount compensation (OVA)]

Initial value
0 [%]
Set a dynamic friction torque in percentage to the rated torque at servo motor rated speed. Or, set a percentage of dynamic
friction force against the continuous thrust at linear servo motor rated speed.
When the responsiveness is low or when the torque/thrust is limited, the efficiency of the servo parameter may be lower.

[Pr. PB13_Machine resonance suppression filter 1 (NH1)]

Initial value
4500 [Hz]
Set the notch frequency of the machine resonance suppression filter 1.
When [Pr. PA08.0 Gain adjustment mode selection] is set to "5" (Quick tuning mode), the setting value of this servo parameter
reflects the adjustment result of quick tuning.
When [Pr. PB01.0 Filter tuning mode selection] is set to "1" (Automatic setting), the values obtained from adaptive tuning are
applied to the setting value of this servo parameter.
When [Pr. PB01.0] is set to "2" (Manual setting), set the notch frequency with this servo parameter.
