No. Symbol
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).
However, when the instantaneous power failure time exceeds 200 ms, and the instantaneous
power failure voltage is less than 70% of the rated input voltage, the power may be normally
turned off 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].

_ _ x x
x x _ _
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.

PX36 LMCP Lost motion compensation positive-side compensation value selection
Set the lost motion compensation for when reverse rotation (CW) switches to forward rotation
(CCW) in increments of 0.01% assuming the rated torque as 100%.
This parameter is supported with software version B4 or later.
PX37 LMCN Lost motion compensation negative-side compensation value selection
Set the lost motion compensation for when forward rotation (CCW) switches to reverse
rotation (CW) in increments of 0.01% assuming the rated torque as 100%.
This parameter is supported with software version B4 or later.
Name and function
Explanation
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.
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.
Explanation
Robust filter selection
0: Disabled
1: Enabled
When you select "Enabled" of this digit, the machine resonance
suppression filter 5 set in [Pr. PX22] is not available.
