Function
selection A-3
_ _ _ x One-touch tuning function selection
0: Disabled
1: Enabled
When the digit is "0", the one-touch tuning is not available.
1h
_ _ x _ For manufacturer setting 0h
_ x _ _ 0h
x _ _ _ Electronic gear selection
0: Electronic gear ([Pr. PA06] and [Pr. PA07])
1: Number of command input pulses per revolution ([Pr. PA05])
2: J3A electronic gear setting value compatibility mode
(Electronic gear ([Pr. PA06] and [Pr. PA07] × 16))
Setting the parameter enables the electronic gear value set in MR-J3-A.
0h
_ _ x x Alarm detail No. setting
Set the digits when you execute the trigger with arbitrary alarm detail No. for the
drive recorder function.
When these digits are "0 0", only the arbitrary alarm No. setting will be enabled.

x x _ _ Alarm No. setting
Set the digits when you execute the trigger with arbitrary alarm No. for the drive
recorder function.
When "0 0" are set, arbitrary alarm trigger of the drive recorder will be disabled.
00h
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".

Function
selection A-4
_ _ _ x Vibration suppression mode selection
0: Standard mode
1: 3 inertia mode
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.

Overshoot
permissible
level
Set a permissible value of overshoot amount for one-touch tuning as a percentage of
the in-position range.
Setting "0" will be 50%.

*AOP5
Function
selection A-5
_ _ _ x Torque limit function selection at instantaneous power failure (instantaneous power
failure tough drive selection)
0: Disabled
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.
