Restrictions on the slight vibration suppression
control
• The slight vibration suppression control is enabled in the position mode.
• The slight vibration suppression control is enabled when [Pr. PA08.0 Gain adjustment mode] is set to "3" (manual mode).

8.3
Operation of slight vibration suppression control
The slight vibration suppression control function changes the gain from the rising edge position of INP (In-position) OFF to ON
to suppress the variation of the pulses generated at a servo motor stop. When the slight vibration suppression control is
enabled, the gain is calculated automatically in the servo amplifier. If the droop pulses exceed the in-position range while
driving the servo motor, the gain changes back to the original gain.
