PE46 LMFLT Lost motion filter setting
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. PE44] and [Pr.
PE45]. 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.

PE47 TOF Torque offset
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 cannot be used for linear servo motors and direct drive motors. Set "0".
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.

PE49 LMCD Lost motion compensation timing
Set the lost motion compensation timing in increments of 0.1 ms.
You can delay the timing to perform the lost motion compensation for the set time.
This parameter is supported with software version B4 or later.

PE50 LMCT Lost motion compensation non-sensitive band
Set the lost motion compensation non-sensitive band. When the model position droop is the
setting value or less, the speed will be 0. Setting can be changed in [Pr. PE48]. Set the
parameter per encoder unit.
This parameter is supported with software version B4 or later.
