Backlash
compensation Set a backlash compensation for reversing command direction.
This parameter compensates backlash pulses against the home position return
direction.
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 0
[pulse]
PT15
LMPL
Software limit
+
(third least
significant
digit) Set an address increasing side of the software stroke limit.
Upper and lower are a set.

[Pr. PT15]
[Pr. PT16]
The stop method depends on "Stop method selection at software limit detection" of
[Pr. PD30]. The initial value is "Quick stop (home position erased)".
Setting a same value with "Software limit -" will disable the software stroke limit. (Refer
to section 7.4.)
Set a same sign for [Pr. PT15] and [Pr. PT16]. A different sign will be recognized as
minus sign data.
When changing the direction to address decreasing, change it from the - side of the
software limit ([Pr. PT17] and [Pr. PT18]). An incorrect order of the setting will trigger
[AL. 37]. Therefore, cycling power may be required after [Pr. PT15] to [Pr. PT18] are all
set.
The unit will be changed to 10

The stop method depends on "Stop method selection at software limit detection" of
[Pr. PD30]. The initial value is "Quick stop (home position erased)".
Setting a same value with "Software limit +" will disable the software stroke
limit. (Refer to section 7.4.)
Set a same sign for [Pr. PT17] and [Pr. PT18]. A different sign will be recognized as
minus sign data.
When changing the direction to the address increasing direction, change it from the +
side of the software limit ([Pr. PT15] and [Pr. PT16]). An incorrect order of the setting
will trigger [AL. 37]. Therefore, cycling power may be required after [Pr. PT15] to
[Pr. PT18] are all set.
