Tuning Mode [TUNMODE]
 Servo amplifier estimates Load inertia moment ratio of the machine or
equipment during real time and automatically tunes the servo gain.
 Parameters which is tuned automatically by servo amplifier, is vary depends on
selection of Group0 ID00 "Auto-Tuning Characteristic [ATCHA]".
 Servo amplifier estimates the Load inertia moment ratio at the time of
acceleration/deceleration. Therefore, for operations only with excessively long
acceleration/deceleration time constants or with only low torque in low velocity,
this mode cannot be used. Also, for operations with high disturbance torque or
with major mechanical clearance, this mode cannot be used. Use in
[01:_AutoTun_JRAT-Fix Automatic Tuning [JRAT Manual Setting].
 Based on Group1 ID14 "Load inertia moment ratio 1 [JRAT1], which has to be
set, the servo amplifier automatically tunes to the best servo gain.
 Parameters for the servo amplifier to automatically tune will vary depending on
"Auto-Tuning characteristic [ATCHA]”.
 This mode is used in order to adjust the servo gain to the machine or equipment
to ensure maximum response as well as when characteristics in auto-tuning are
insufficient.
