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, 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. PX28 SEMI-F47 function -
Instantaneous power failure detection time].
To enable the torque limit function at instantaneous power failure,
select "Enabled (_ 1 _ _)" of "SEMI-F47 function selection" in [Pr.
PX25].
This parameter setting is used with servo amplifier with software
version B0 or later.

PX24 FRIC Machine diagnosis function - Friction judgment speed
Set a (linear) servo motor speed that divides a friction estimation area into high and low during
the friction estimation process of the machine diagnosis.
Setting "0" will set a value half of the rated speed.
When your operation pattern is under the rated speed, we recommend that you set a half
value of the maximum speed.

PX25 *TDS Tough drive setting
Alarms may not be avoided with the tough drive function depending on the situations of the
power supply and load fluctuation.
You can assign MTTR (During tough drive) to pins CN3-9, CN3-13, and CN3-15 with [Pr.

Selecting "1" enables to suppress vibrations by automatically
changing setting values of [Pr. PB13 Machine resonance

PX28 CVAT SEMI-F47 function - Instantaneous power failure detection time
Set the time until the occurrence of [AL. 10.1 Voltage drop in the control circuit power].
This parameter setting range differs depending on the software version of the servo amplifier
as follows.
Software version C0 or later: Setting range 30 ms to 200 ms
Software version C1 or earlier: Setting range 30 ms to 500 ms
To comply with SEMI-F47 standard, it is unnecessary to change the initial value (200 ms).
When the instantaneous power failure time exceeds 200 ms, and if the instantaneous power
failure voltage is less than 70 % of the rated input voltage, the power may be turned off
normally even if a value larger than 200 ms is set in the parameter.
To disable the parameter, set "Disabled (_ 0 _ _)" of "SEMI-F47 function selection" in [Pr.
PX25].

Explanation
Initial
value
_ _ 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.

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".
PX30 DRT Drive recorder switching time setting
Set the drive recorder switching time.
When a USB communication is cut during using a graph function, the function will be changed
to the drive recorder function after the setting time of this parameter.
When a value from "1" to "32767" is set, it will switch after the setting value.
However, when "0" is set, it will switch after 600 s.
When "-1" is set, the drive recorder function is disabled.
