PT14 Set a backlash compensation for reversing command direction.
*BKC
This parameter compensates backlash pulses against the home position return
Backlash direction.
compensation
For the home position ignorance (servo-on position as home position), this turns on
SON (Servo-on) and decides a home position, and compensates backlash pulses
against the first rotation direction.
Setting range: 0 to 65535

The stop method depends on "Stop method selection at software limit detection" of
[Pr. PD30]. The initial value is "Quick stop (home position erased)".
PT16 Setting a same value with "Software limit -" will disable the software stroke limit. (Refer
to section 7.4.)
