7.2 Detailed list of parameters
Function
Set a range of the command remaining distance which outputs rough match.
The unit will be as follows depending on the positioning mode.
• Point table method
STM
The unit can be changed to 10
[Pr. PT01].
The unit [degree] is used with servo amplifiers with software version A6 or later.
• 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.
Setting range: 0 to 65535
Set the backlash compensation.
Setting a value other than "0" in the cyclic synchronization mode triggers [AL. 37].
Setting range: 0 to 65535
Set an address increasing side of the software stroke limit.
The combination of the upper and lower digits makes one address.
Set an address in hexadecimal.
Setting address:
Upper four digits Lower four digits
For the μm, inch, and pulse units, setting "Software limit -" to a value greater to or equal to "Software
limit +" disables the software limit. For the degree unit, setting the same value as for "Software limit
-" disables the software limit.
When changing the parameter setting with MR Configurator2, change it during servo-off or in the
home position return mode.
STM
The unit can be changed to 10
[Pr. PT01].
The unit [degree] is used with servo amplifiers with software version A6 or later.
Setting range: 8000 0000h to 7FFF FFFFh (-2147483648 to 2147483647)
Set an address decreasing side of the software stroke limit.
The combination of the upper and lower digits makes one address.
Set an address in hexadecimal.
Setting address:
Upper four digits Lower four digits
For the μm, inch, and pulse units, setting "Software limit -" to a value greater to or equal to "Software
limit +" disables the software limit. For the degree unit, setting the same value as for "Software limit
+" disables the software limit.
When changing the parameter setting with MR Configurator2, change it during servo-off or in the
home position return mode.
