Rough match
output range Set the range of the command remaining distance outputs for the rough
match (S_CPO/CPO).
The unit will be as follows depending on the positioning mode.
For point table method
Is changed to 10 STM [μm], 10 (STM-4) [inch], or [pulse] with the setting of
[Pr. PT01].
Indexer method
It will be command unit [pulse]. (unit of a load-side rotation expressed
by the number of servo motor resolution pulses)
Refer to the Function column of [Pr. PA10] for the command unit
[pulse].
Setting range: 0 to 65535
0
Refer to
Function

PT14
*BKC
Backlash
compensation Set a backlash compensation amount to be corrected when the
command method is reversed.
This parameter compensates backlash pulses against the home position
return direction.
For the home position ignorance (servo-on position as home position),
once the home position is established with servo-on condition, for the
start of the rotating direction, compensates backlash pulses in the
opposite direction.
Setting range: 0 to 65535 0

(Lower four
digits) Set an address increasing side of the software stroke limit.
Upper and lower are a set.
Set an address in hexadecimal.

[Pr. PT15]
[Pr. PT16]
The stop method follows the "Stopping method at software limit detection"
of [Pr. PD35]. The initial value is "slow stop".
Setting the same value in "Software limit -" disables the software limit.
(Refer to section 4.3.)
To change the setting of this parameter, change with the servo-off or with
the home return mode.
When changing the setting of the positioning mode during servo on,
changing the setting in a certain order triggers [AL. 35], [AL. 69], or [AL.
98].
The unit can be changed to 10
STM [μm], 10 (STM-4) [inch], or [pulse] with the
setting of [Pr. PT01].
This parameter corresponds to "Max position limit (Index: 607Dh, Sub: 2)".
When this parameter is mapped to the link device of CC-Link IE Field
Network Basic, do not write the parameter value with MR Configurator2,
as the controller overwrites the parameter value written with MR
Configurator2.
