Lost motion

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 available with servo amplifiers with software version B4 or later.
Setting range: 0 to 30000 0
[0.01%]
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 available with servo amplifiers with software version B4 or later.
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 cannot be used for
linear servo motors and direct drive motors. Set 0.00%.
This parameter is available with servo amplifiers with software version B4 or later.
Setting range: -10000 to 10000 0

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 available with servo amplifiers with software version B4 or later.

LMCT
Lost motion
compensation
non-sensitive
band Set the lost motion compensation non-sensitive band. When the fluctuation of the
droop pulse 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 available with servo amplifiers with software version B4 or later.
Setting range: 0 to 65535 0
