PE46
LMFLT
Lost motion
filter setting
Set the time constant of the lost motion compensation filter in increments of 0.1 ms.
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.
This function will be enabled in the profile position mode.
Setting range: 0 to 30000
0
[0.1 ms]
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 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

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 function will be enabled in the profile position mode.
Setting range: 0 to 30000

LMCT
Lost motion
compensation
non-sensitive
band
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.
PE48]. Set the parameter per encoder unit.
This function will be enabled in the profile position mode.
Setting range: 0 to 65535
