■When positioning to the same direction
The following shows an example of behavior for the following setting values.
In this example, point table number 1 is the absolute position command method, point table number 2 is the relative position
command method, and point table number 3 is the absolute position command method.

1 500
2 500

*1 Set "0" or "2" for the auxiliary function of the last point table among consecutive point tables.
0: When using the point table as the absolute position command method
2: When using the point table as the relative position command method

*1 The bit turns on when the droop pulse of the command unit is equal to or less than the setting value of [Pr. PA10 In-position range].
*2 The bit turns on when the command remaining distance is equal to or less than the setting value of [Pr. PT12_Rough match output
range (CRP)]. The bit is off during continuous operation.
*3 The bit turns on when S_INP (in-position) is on and command remaining distance is "0". The bit is off during continuous operation.
