value 
selection 
  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%. 
This parameter is available with servo amplifiers with software version C5 or later.

  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%.

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 C5 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. 
This parameter is available with servo amplifiers with software version C5 or later.
