6.3 SVA Parameter Details

6-33

Encoder Position
at Shutdown
(Lower place)

OLC038

-2

to 2

-1

This parameter is used in the following two ways
and should be used with care.

1. Lower-place 2 Words of Encoder Position at

Shutdown
This parameter is valid when the motion fixed
parameter: 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 OWC02D: 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 shutdown.

2. Position Buffer Access Number

When bit 14 of OWC021: Position Buffer
Write or bit 15 of OWC021: 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.” It is used when an OWC020: Motion
Command Code is used in Position Control
Mode.
