1 OVERVIEW
1.2 Features
The Motion CPU and Multiple CPU system have the following features.
1.2.1 Features of Motion CPU
(1) Q series PLC Multiple CPU system
(a) Load distribution of processing can be performed by controlling the
complicated servo control with Motion CPU and the machine control or
information control with PLC CPU. Therefore, the flexible system
configuration can be realized.
(b) The Motion CPU and PLC CPU are selected flexibly, and the Multiple CPU
system up to 4 CPU modules can be realized.
The Motion CPU module for the number of axis to be used can be selected.
Q173DCPU : Up to 32 axes
Q172DCPU : Up to 8 axes
The PLC CPU module for the program capacity to be used can be selected.
(One or more PLC CPU is necessary with the Multiple CPU system.)
Q03UDCPU : 30k steps
Q04UDHCPU : 40k steps
Q06UDHCPU : 60k steps
(c) The device data access of the Motion CPU and the Motion SFC program
start can be executed from PLC CPU by the Motion dedicated PLC
instruction.
(2) High speed operation processing
(a) The minimum operation cycle of the Motion CPU is made 0.44[ms], and it
correspond with high frequency operation.
(b) High speed PLC control is possible by the universal model QCPU.
(For LD instruction)
Q03UDCPU : 20[ns]
Q04UDHCPU : 9.5[ns]
Q06UDHCPU : 9.5[ns]
