3.4 I/O Signals from/to the CPU Module
3.4.2 Details of input signals
(17)OPR start complete signal (X20)
This signal turns on when OPR process starts after OPR start signal (Y20) was turned on.
When OPR start signal (Y20) is turned off after the start of OPR, this signal turns off.
(18)Absolute positioning start complete signal (X21)
This signal turns on when positioning process starts after Absolute positioning start signal (Y21) was turned on.
When Absolute positioning start signal (Y21) is turned off after the start of the positioning, this signal turns off.
(19)Forward start complete signal (X22)
This signal turns on when positioning process starts after Forward start signal (Y22) was turned on.
When Forward start signal (Y22) is turned off after the start of the positioning, this signal turns off.
(20)Reverse start complete signal (X23)
This signal turns on when positioning process starts after Reverse start signal (Y23) was turned on.
When Reverse start signal (Y23) is turned off after the start of the positioning, this signal turns off.
(21)Synchronization flag (X24)
This signal turns on when the CPU module becomes accessible to the QD73A1 after the power was turned off
then on, or after the CPU module was reset.
When the module synchronization setting of the CPU module is set to asynchronous, use this signal as an
interlock to access the QD73A1 from a sequence program.
(22)Zero/gain adjustment data writing complete flag (X2A)
This signal turns on when zero/gain adjustment value writing to the QD73A1 is completed after Zero/gain
adjustment data writing request signal (Y1A) was turned on.
When Zero/gain adjustment data writing request signal (Y1A) is turned off, this signal turns off.
Use this signal as an interlock condition to turn on/off Zero/gain adjustment data writing request signal (Y1A)
when writing the zero/gain adjustment value to the QD73A1.
For details on zero/gain adjustment, refer to the following.
