4 POSITIONING DEDICATED SIGNALS
4.4 Special Relays (SM)
There are 2256 special relay points of SM0 to SM2255 in the Motion CPU.
Of these, devices in a Table 4.4 are used for the positioning control.
The special relay list used for the positioning control is shown below.
(Refer to " Q173D(S)CPU/Q172D(S)CPU Motion controller Programming Manual
(COMMON)" for the application of special relays except below.)

(1) PCPU READY complete flag (SM500) ......................... Status signal
This flag is used as judgement of the normal or abnormal in the Motion CPU side
using the sequence program.
(a) At leading edge of PLC ready flag (M2000), the fixed parameters, servo
parameters and limit switch output data are checked, and if error is not
detected, this flag turns on.
The servo parameters are written to the servo amplifiers and the M-codes
are cleared.
(b) This flag turns off when the PLC ready flag (M2000) turns off.
