ZRN (Zero Return)
Applicable CPU Modules
Note:
These instructions cannot be used with FT1A-H40RC and FT1A-B40RC.
Valid Devices
Special data registers cannot be designated as S1. Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be
designated as D1. Caution: The first digit of the internal relay number must be 0 (not 1 to 7). Otherwise, the ZRN instruction will not operate
correctly.
The ZRN instruction outputs pulses while the proximity signal is off.
When the input is on, pulses of the initial pulse frequency specified by S1
and S1+1 are output until the proximity signal specified by S3 turns on.
When the proximity signal turns on, pulses of the creep pulse frequency
specified by S1+2 and S1+3 are output until the proximity signal turns
off.
When the proximity signal turns off, pulse output stops.
