Access
Number OL††38
-2 31 to 2 31 -1
Used when an OW††20: Motion Command Code is
used in Position Control Mode.
This parameter is used in the following two ways and
should be used with care.
„ Lower-place 2 Words of Encoder Position at Shut-
down
This parameter is valid when the motion fixed parame-
ter: Encoder Selection is set to absolute encoder (= 1)
and motion fixed parameter: Axis Selection (bit 5 of
the Motion Controller Function Selection Flags) is set
to an infinite length axis ( = 1).
When bit 2 of OW††2D: ABS System Infinite
Length Position Control Data Load Request turns ON,
the data set at this parameter will be treated as the
lower-place two words of the encoder position at shut-
down.
„ Position Buffer Access Number
When bit 14 of OW††21: Position Buffer Write or
bit 15 of OW††21: Position Buffer Read turns ON,
the data set at this parameter will be treated as the
buffer number of the position buffer. The setting range
for this parameter is 1 to 256 and it is not valid if set to
“0.”

59 Upper-place
Two Words of
Encoder Posi-
tion at Shut-
down or
Position Buffer
Write Data OL††3A -2 31 to 2 31 -1
Used when an OW††20: Motion Command Code is
used in Position Control Mode.
This parameter is used in the following two ways and
should be used with care.
„ Upper-place 2 Words of Encoder Position at Shut-
down
This parameter is valid when the motion fixed parame-
ter: Encoder Selection is set to absolute encoder (= 1)
and motion fixed parameter: Axis Selection (bit 5 of
the Motion Controller Function Selection Flags) is set
to an infinite length axis ( = 1).
When bit 2 of OW††2D: ABS System Infinite
Length Position Control Data Load Request turns ON,
the data set at this parameter will be treated as the
upper-place two words encoder position at shutdown.
„ Position Buffer Write Data
When bit 14 of OW††21: Position Buffer Write turns
ON, the data set at this parameter will be written as
absolute position data to the position buffer specified
at OL††38.
