9. Specify the number of velocity pulses and the number of position
pulses.
Semi–closed Full–closed
Command unit (µm) 1 0.1 1 0.1
Initialization bit b0=0 b0=1 b0=0 b0=1
Number of velocity pulses 8192 819 8192 819
Number of position pulses 12500 1250 Np Np/10
Np:Number of position pulses from the separate detector when
the motor makes one turn
When using a separate detector (full–closed mode), also specify
the following parameters:
– Series 15, 16, 18, 20, 21
b7 b6 b5 b4 b3 b2 b1 b0
1807
PFSE
⇑
Must be specified only for Series 15
PFSE(b3) The separate position detector is:
0:Not used
1:Used
NOTE
This parameter is used only for Series 15.
b7 b6 b5 b4 b3 b2 b1 b0
1815 OPTX
⇑
Must be specified for all NCs.
OPTX(b1) The separate position detector is:
0:Not used
1:Used
NOTE
For Series 16, 18, 20, and 21, setting this parameter causes
bit 3 of parameter No. 2002 to be set to 1 automatically.
– Series 0–C

37 STP8 STP7 STP4 STPZ STPY STPX
STPX to 8 The separate position detector is:
0:Not used for the X–axis, Y–axis, Z–axis, fourth axis,
seventh axis, or eighth axis
1:Used for the X–axis, Y–axis, Z–axis, fourth axis, seventh
axis, and eighth axis
10. Specify the reference counter. The reference counter is used in
making a return to the reference position by a grid method. The
value to be specified is the number of pulses necessary for the
