Setting Method 2
Using the Incremental Value Addition Method (When Bit 5 in OW
Incremental value = Target position (a value between 0 and POSMAX) - Previous target position
(a value between 0 and POSMAX) + POSMAX × n
OL
Previous target position: The directly specified value or the value that was stored in a location
such as an M register.
n is the number of POSMAX turns needed to move from the current position (CPOS) to the tar-
get position. When the distance between the target position and the current position is within
the first turn, n is 0.
Using the Absolute Value Specification Method (When Bit 5 in OW
1)
Important
Incremental value = Target position (a value between 0 and POSMAX) - Previous target position
(a value between 0 and POSMAX) + POSMAX × n
OL
Previous target position: The directly specified value or the value that was stored in a location
such as an M register.
n is the number of POSMAX turns needed to move from the current position (CPOS) to the tar-
get position. When the distance between the target position and the current position is within
the first turn, n is 0.

Make sure that the absolute value specification method setting is retained after the target posi-
tion is changed.
