6.1 Difference of Motion CPU Configuration
6.1.1 System configuration
The following figure shows the differences between the basic system of A-Motion and basic system of
QDS-Motion.
• The PLC function and the motion function are integrated in one A-motion CPU. However, in
QDS-motion, they are in different CPUs.
• A-Motion is compatible with SSCNET as a servo system network, but QDS-Motion is compatible with
SSCNET III or SSCNET III/H. Servo amplifiers connectable to each motion are also different.
• A motion module A172SENC (Pulse generator/synchronous encoder interface module) is replaced
with a motion module Q172DLX (Servo external signal interface module), Q172DEX (Synchronous
encoder interface module), or Q173DPX (Manual pulse generator interface module).
• A base unit is changed to a Q series multiple CPU high speed base unit. As a result, motion modules
(Q172DLX, Q173DEX, and Q172DPX) cannot be installed in the CPU slot and Slot 0 to 2.
