1.2.5 Precautions at the program appropriation
(Motion CPU A series
Precautions when appropriating the Motion program created by the Motion CPU A series to
Q173CPU(N)/Q172CPU(N) are shown below.
(1) Multiple CPU system control
The PLC CPU and Motion CPU is the same module in the Motion controller A
series, however, the Multiple CPU system which controls a sequence control by
the PLC CPU and a motion control by the Motion CPU module is used in
(2) Devise use
(a) The devises of PLC CPU and Motion CPU is same in the Motion controller
A series, however, since the each CPU has independent device in
Q173CPU(N)/Q172CPU(N), it is necessary to execute the automatic refresh
for data exchange.
(Note) : The devices of "D, W, M, Y, B, #" can be used for automatic refresh.
(b) The motion register "#" is added newly in Q173CPU(N)/Q172CPU(N).
The motion register is usually shown by "#", however, it is shown "#@" in the
Motion program. Expression only "#" in the Motion program is the same as
"#D" which specified the data register "#D". (It is for holding compatibility
with Motion controller A series.)
(c) The positioning dedicated devices in Q173CPU(N)/Q172CPU(N) are the
same level as them in A273UHCPU/A173UHCPU.
However, "TT, TC, CT, CC" cannot be used.
Also, the following contents are added/changed.
1) DNC status : (M4320 to M4323)
2) Control program monitor devices : (D1440 to D1535)
3) Control change registers 2 (Override ratio) : (D1536 to D1631)
(3) Motion CPU parameter setting
(a) Re-set the system setting to compensate for the system configuration.
(b) Although the axis data (fixed-parameters, home position return data, JOG
operation data or servo parameters) and parameter blocks can be
appropriated, be careful that the following contents are changed.
1) The electronic gear setting : 16 bit
2) The home position return for proximity dog type 2, count type 2, count
type 3, data set type 2, dog cradle type, stopper type and limit switch
combined type are added.
However, the setting files created by the Motion CPU (A series) cannot be
(c) Multiple CPU setting is added newly.
