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 DRT Lost motion compensation positive-side compensation value selection
(Note) 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
(Note) 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.
PX38 LMFLT Lost motion filter setting
(Note) Set the time constant of the lost motion compensation filter in increments of 0.1 ms.
If the time constant is "0", the torque is compensated with the value set in [Pr. PX36]
and [Pr. PX37]. If the time constant is other than "0", the torque is compensated with
the high-pass filter output value of the set time constant, and the lost motion
compensation will continue.
This parameter is supported with software version B4 or later.
PX39 TOF Torque offset
(Note) Set this when canceling unbalanced torque of vertical axis. Set this assuming the
rated torque of the servo motor as 100%.
The torque offset does not need to be set for a machine not generating unbalanced
torque.
The torque offset set with this parameter will be enabled in the position control
mode, speed control mode, and torque control mode. Input commands assuming
torque offset for the torque control mode.
This parameter is supported with software version B4 or later.
Note. MR-J4W2-_B servo amplifier is "for manufacturer setting".
