4. DESCRIPTION OF PARAMETERS
B–63090EN/02
90
[Data type] Bit axis
OPTx Position detector
0 : A separate pulse coder is not used.
1 : A separate pulse coder is used.
For an absolute–position system using Inductosyn, set this parameter to 1.
DCLx As a separate position detector, the linear scale with reference marks is:
0 : Not used.
1 : Used.
NOTE
When using the linear scale with reference marks, also set
the OPTx parameter (bit 1 of parameter No.1815) to 1.
APZx Machine position and position on absolute position detector when the
absolute position detector is used
0 : Not corresponding
1 : Corresponding
NOTE
When an absolute position detector is used, after primary
adjustment is performed or after the absolute position
detector is replaced, this parameter must be set to 0, power
must be turned off and on, then manual reference position
return must be performed. This completes the positional
correspondence between the machine position and the
position on the absolute position detector, and sets this
parameter to 1 automatically.
APCx Position detector
0 : Other than absolute position detector
1 : Absolute position detector (absolute pulse coder)
For an absolute–position system using Inductosyn, set this parameter to 1.

1817
#6 #5 #4
SCPx
#3 #2 #1 #0
NOTE
When this parameter has been set, the power must be
turned off before operation is continued.
[Data type] Bit axis
SCPx If bit 2 (DC2) of parameter No. 1802 is set to 1, the scale zero point of the
linear scale with absolute addressing reference marks is:
0: On the negative direction side. (Viewed from the scale zero point, the
reference position is on the positive direction side.)
1: On the positive direction side. (Viewed from the scale zero point, the
reference position is on the negative direction side.)
