2 SYSTEM CONFIGURATION
(e) Axis No. of manual pulse generator/synchronous encoder
The axis No. of synchronous encoder built-in interface in Motion CPU is set
depending on the axis No. assigned to Q172DEX and Q173DPX.
1) Any built-in interface in Motion CPU will automatically be assigned an
axis No. one integer greater than the number of encoders connected to
any Q172DEX and Q173DPX.
2) Motion module installed to the smallest slot number of the Main base
unit is the 1st.
3) Axis No. P1 to P12 of the synchronous encoder can be used.
4) Axis No. P1 to P3 of the manual pulse generator can be used.
When the manual pulse generator is used with the built-in interface in
Motion CPU, Q173DPX cannot be used.
The setting example for the axis No. of manual pulse generator/synchronous
encoder is shown below.
(Example) Q173DSCPU use (Q172DEX: 2 modules, Q173DPX: 2 modules)

POINTS
For advanced synchronous control method, set the axis No. of synchronous
encoder in the synchronous encoder axis parameter.
Refer to the "Q173DSCPU/Q172DSCPU Motion controller Programming Manual
(Advanced Synchronous Control)" for details.
