Slight vibration suppression control selection
Select the slight vibration suppression control.
0: Disabled
1: Enabled
To enable the slight vibration suppression control, set "Gain adjustment mode
selection" to "Manual mode (_ _ _ 3)" in [Pr. PA08]. Slight vibration suppression
control selection cannot be used in the velocity mode.

PI-PID switching control selection
0: PI control enabled
(Switching is enabled by PID switching signal from upper side (C_PC) and Input
device PC (Proportional control).)
3: Continuous PID control enabled
If the servo motor at a stop is rotated even for a pulse due to any external factor, it
generates torque to compensate for a position shift. When the servo motor shaft is
to be locked mechanically after positioning completion (stop), enabling PID control
and completing positioning simultaneously will suppress the unnecessary torque
generated to compensate for a position shift.

Gain
switching
condition
This is used to set the value of gain switching (command frequency, droop pulses,
and servo motor speed) selected in [Pr. PB26].
The set value unit differs depending on the switching condition item. (Refer to
section 7.2.3.)
The unit "r/min" will be "mm/s" for linear servo motors.
