2. REPLACEMENT PROPOSAL FROM A-MOTION TO QDS-MOTION

6. POINTS AND PRECAUTIONS OF REPLACEMENT

6.1 Difference of Motion CPU Configuration

6.1.1 System configuration

The differences between basic system of A-Motion and basic system of QDS-Motion are shown in the

following chart.

• 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.

• For the connection between QDS-Motion and a personal computer, RS-422 and SSCNET cannot be

used. Connect them with Ethernet (Direct connection to QDS-Motion), USB, RS-232, or Ethernet

(Connection via PLC).
