PA23 _ _ x x Alarm detail No. setting
DRAT Set the digits when you execute the trigger with arbitrary alarm detail No. for the
drive recorder function.
Drive
recorder When these digits are "0 0", only the arbitrary alarm No. setting will be enabled.
arbitrary
x x _ _ Alarm No. setting
alarm trigger
Set the digits when you execute the trigger with arbitrary alarm No. for the drive
setting
recorder function.
When "0 0" are set, arbitrary alarm trigger of the drive recorder will be disabled.
Setting example:
To activate the drive recorder when [AL. 50 Overload 1] occurs, set "5 0 0 0".
To activate the drive recorder when [AL. 50.3 Thermal overload error 4 during operation] occurs, set "5 0 0 3".
PA24 _ _ _ x Vibration suppression mode selection
AOP4 0: Standard mode
Function 1: 3 inertia mode
selection A-4
2: Low response mode
When you select the standard mode or low response mode, "Vibration suppression
control 2" is not available.
When you select the 3 inertia mode, the feed forward gain is not available.
Before changing the control mode during the 3 inertia mode or low response mode,
stop the motor.

PA25 Set a permissible value of overshoot amount for one-touch tuning as a percentage of
the in-position range.

PA26 _ _ _ x Torque limit function selection at instantaneous power failure (instantaneous power
failure tough drive selection)
*AOP5
0: Disabled
Function
selection A-5 1: Enabled
When an instantaneous power failure occurs during operation, the torque at
acceleration is limited to save electric energy charged in the capacitor in the servo
amplifier and the time until [AL. 10.2 Voltage drop in the main circuit power] occurs is
extended with the instantaneous power failure tough drive function. Consequently,
you can set a longer time in [Pr. PF25 SEMI-F47 function - Instantaneous power
failure detection time]. The torque limit function at instantaneous power failure is
enabled when "SEMI-F47 function selection" in [Pr. PA20] is "Enabled (_ 1 _ _)".
This parameter setting is used with servo amplifier with software version A6 or later.
