Hi,
in order to be able to control a Fanuc Serial spindle under 1 rev means that the 1rev pulse from the position coder might be a "border case" for detection purpose.

therefore the spindle needs to be controled in servo mode, which brings only 2 methods to mind, rigid tapping or threading G32 commands.

should your machine be fitted with a analog spindle, i.e. not a fanuc spindle, then the capabilities of the drive is in question. then timing could be your only option.

You need to do a few tests on the machine to find out what you can do
M19 is a positional stop and you need this as a starting point--some Fanuc controls can do multipal stop point like M19/M119/M219

Then the next one is can you machine toan s value or c value with it
M19 C100
This is what you need for what you want

M19 C0
G91 C360.0
G04 X1.0(dwell)
G91 C-360.0
G04 X1.0(dwell)
G90
