Chapter 2. MC Programming
10) XSET2
Input type
XSET2 <P variable> or XSET2 <L variable1> <L variable2>
Terminology
<P variable>: Set the variable for a position from the Position Table.(P0 ~ P99)
<L variable>: Set the variable for a position from the L-VAR Table.(L0 ~ L1999)

P variable, L variable
Explanation
The X-axis current position(absolute coordinate) and the motor position(machine
coordinate) are reset to the set variable coordinate.
The action is same as the XSET command, and the machine coordinate of X-axis motor
position, i.e. the encoder coordinate is reset, too.
Even though automatic operation ends, the coordinate isn’t recovered.
In closed loop control of MCU-XA2 and MCU-XP2, the position of a servo motor shifts as
much as the servo motor offset. For the case of using L variable, the 1
st
L variable
means X-axis coordinate. The 2
nd
L variable is simply ignored.

XSET2 P2
XSET2 L2 L3

LL1
Reset the X-axis position by using the X-axis position value of a P2
variable.
Reset the X-axis position by using a L2 variable value.
Reset the X-axis position by using the X-axis position value of a P
variable pointed out by a L0 variable.
Reset the X-axis position by using an L variable value pointed out by a
L0 variable.
Example
VEL 0
MOV P0
XSET2 P2
VEL 1
MOV P1
Setting value of P0: 50.000, 30.000
Setting value of P2: 10.000, 10.000
Setting value of P1: 60.000, 40.000

The position values 50.000 and 30.000 are reset
to 10.000 and 30.000 by the XSET2 P2.
