No. 1023 See <1>. Servo axis number for each axis
No. 1815 See <2>. Settings for separate pulse coder
No. 1902, B0 See <3>. FSSB manual setting enabled
No. 1905 See <4>. (Bit type parameter)
No. 1910 to 1919 See <5>. Conversion table value for slave number

<1> Servo axis number setting
1023 Setting of servo axis number for each axis
[Data type] Byte axis
[Valid data range] 1, 2, 3, ..., the number of controlled axes
Set the number of the servo axis to which each controlled axis
corresponds. Refer to the description of FSSB setting in the connection
<2> Settings for separate pulse coder
#3 #2 #1
APC 0 : The position detector is not an absolute pulse coder.
1 : An absolute pulse coder is used as the position detector.
APZ The reference position of the absolute pulse coder is:
0 : Not established.
1 : Established.
(This bit is set to 1 automatically after the reference position has been
When using the serial a/b pulse coder, to rewrite APZ manually from
0 to 1 without performing reference position return, in the
battery–backed–up condition rotate the motor at least one turn, turn
the power off then back on, then change the APZ setting from 0 to 1.
OPT 0 : The pulse coder built into the motor is used for position detection.
1 : A separate pulse coder and linear scale are used.
<3> FSSB manual setting
#6 #5 #4 #3 #2 #1 #0
[Data type] Bit
FMD The FSSB setting mode is set to:
0 : Automatic setting mode.
1 : Manual setting 2 mode.
