[Data type] Bit axis
OPTx As a position detector:
0 : A separate pulse coder is not used.
1 : A separate pulse coder is used.
(To use a linear scale with absolute addressing reference marks, set this bit
to 1.)
DCLx As a separate position detector:
0 : A linear scale with absolute addressing reference marks is not used.
1 : A linear scale with absolute addressing reference marks is used.

[Data type] Bit
DC4 When establishing the reference position using the linear scale with
absolute addressing reference marks:
0 : Three referencemarks are detected to determinethe absoluteposition.
1 : Four reference marks are detected to determine the absolute position.
