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) The load of control processing for each CPU can be distributed by
controlling the complicated servo control with the Motion CPU, and the
machine control or information control with the PLC CPU, and 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.
Q173HCPU : Up to 32 axes
Q172HCPU : Up to 8 axes
(Note): Combination with Q173CPU(N)/Q172CPU(N) is also possible.
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.)
Q00CPU : 8k steps
Q01CPU : 14k steps
Q02CPU, Q02HCPU : 28k steps
Q06HCPU : 60k steps
Q12HCPU : 124k steps
Q25HCPU : 252k steps
(c) The device data access of the Motion CPU and the Motion SFC program
(SV13/SV22)/Motion program (SV43) 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] (so far,
the ratio of 2 times), and it correspond with high frequency operation.
(Note): The minimum operation cycle of Q173CPU(N)/Q172CPU(N) is 0.88[ms].
(b) High speed PLC control is possible by the Q series PLC CPU.
