ɾDamping Reinforcement
ɹDamping is reinforced by changing the level of KICK pulses, which is set with the KICK2, with
ɹservo control turned on in KICK operation.
ɹɹɹMode 1: The inverted pulse in full brake speed control and servo control is set as KICK2.
ɹɹɹMode 2: In addition to the condition in mode 1, the inverted pulse drive after the target track
ɹɹɹɹɹɹ is passed is also set as KICK2.
˞ Refer to 7-1 (4) (F)-9 for the KICK pulse level setting.
