PE46 Set the time constant of the lost motion compensation filter in increments of 0.1 ms.
LMFLT When "0" is set, the torque is compensated with the value set in [Pr. PE44] and [Pr. PE45]. When
other than "0" is set, the torque is compensated with the high-pass filter output value of the set time

constant, and the lost motion compensation will continue.
filter setting
This function will be enabled in the profile position mode.
Setting range: 0 to 30000
PE47 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
TOF
unbalanced torque.
Torque offset
The torque offset set with this parameter will be enabled in the position control mode, speed control
mode, and torque control mode. Input commands considering the torque offset in the torque control
mode.
Setting range: -10000 to 10000

PE50 Set the lost motion compensation non-sensitive band. When the fluctuation of droop pulses is
equal to or less than the setting value, the speed will be 0. The setting unit can be changed in [Pr.
