1: Used in absolute position detection system
2: Used in incremental system
The absolute position detection system cannot be used while an incremental type encoder is used. Enabling
absolute position detection system will trigger [AL. 37 Parameter error].
Additionally, the setting is enabled only in the standard control mode. Setting other than "0" in other operation
modes triggers [AL. 37 Parameter error].
The setting of this digit is used by servo amplifier with software version A1 or later. 0h
PA23
DRAT
Drive recorder
arbitrary alarm
trigger setting _ _ 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. 00h
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.

OTHOV
One-touch tuning -
Overshoot
permissible level

Set a permissible value of overshoot amount for one-touch tuning as a percentage of the in-position range.
Note that setting "0" will be 50%.
Setting range: 0 to 100 0 [%]
PA26
*AOP5
Function selection
A-5 _ _ _ x Torque limit function selection at instantaneous power failure
0: Disabled
1: Enabled
When an instantaneous power failure occurs during operation, you can save electric energy charged in the
capacitor in the servo amplifier by limiting torque at acceleration. You can also delay the time until [AL. 10.2
Voltage drop in the main circuit power] occurs with instantaneous power failure tough drive function. Doing
this will enable you to 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 _ _)". 0h
