Backlash compensation
Set [Pr. PT14 Backlash compensation] to stop the servo motor at the compensated position for the setting value of backlash
compensation when reversing the command direction of automatic operation.
Backlash compensation is available with servo amplifiers with software version A8 or later.
Before use, make sure that the meshing gap between the gears or feed screws on the machine side and the
motor side occurs on one side only.
The timing chart is for when the travel distance between stations is set to 1000 and the backlash compensation amount is set
to 10.
Home position return method in which the servo motor operates during home position
return
The backlash compensation direction is determined by the home position return direction just before home position return
completion.
