Notes:
If a pulse output instruction is simultaneously executed with the same output, a user program execution error will occur. Error code 48 will be
•
stored in D8006 and instructions that are executed later will be canceled.
The ZRN instruction cannot be used in an interrupt program. If used in an interrupt program, a user program execution error will occur.
•
Error code 18 will be stored in D8006 and instruction execution will be canceled.
If a pulse output instruction is executed with the relay output type, a user program execution error will occur. Error code 19 will be stored in
•
D8006 and instruction execution will be canceled.
For details about the user program execution errors, see "User Program Execution Errors" on page 3-10.

(1) The rise in the proximity signal is detected and the frequency
starts being decreased.
The fall in the proximity signal is detected and the origin signal
(2)
starts being monitored.
(3) The rise in the origin signal is detected and pulse output is
stopped.
When pulse output stops, the complete signal turns on at the
(4)
[t]
same time.
(5) The on period for the complete signal is one scan or longer but
less than two scans.
