PE44 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%.

PE46 Set the time constant of the lost motion compensation filter in increments of 0.1 ms.
LMFLT 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

compensation will continue.
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
TOF
for a machine not generating unbalanced torque.
Torque offset
The torque offset cannot be used for linear servo motors and direct drive motors. Set
0.00%.
The torque offset set with this parameter will be enabled in the position mode,
velocity mode, and torque mode. Input commands assuming torque offset for the
torque mode.
Setting range: -10000 to 10000
