SRAM initialization
The parameters related to the I/O Link-II function are stored in the
SRAM on the I/O Link-II board. When using the I/O Link-II board for
the first time, initialize the SRAM on the board according to the
procedure below.
(1) While the power to the CNC is off, set the rotary switch (SW4-1)
on the board to F.
(2) Turn on the power, and check that the normal CNC screen
appears. (At this time, the SRAM is initialized.)
(3) Turn off the power, then reset SW4-1 from F to 0. Finally, turn
on the power again.
