External I/O
signals
• This register stores the on/off status of external I/O
signals.
When an OPR method with the OPR retry function (Near-
point dog method, Count 1, Count 2) is performed, a value
indicating the status of the upper limit signal or the lower limit
signal is stored to the external command signal.
*1
*1 When an OPR method with the OPR retry function is
performed even once, a value indicating the status of
the upper limit signal or the lower limit signal will be
stored until when speed/position switching control is
started.

• This register stores "0" when machine OPR control is
started.
• After machine OPR control is started, this register stores a
travel distance from the point where the near-point dog
signal turns on (The point is set to "0".) to the point where
machine OPR control is completed.
*1
• When an OPR method is set to Stopper 3, this register
always stores "0".

• This register stores the data No. of positioning being
executed. (A storage value will be held until the next
control starts.)
• "0" is stored when JOG operation or machine OPR control
is started.
• "1" is stored when high-speed OPR control is started.
• "1" is stored when positioning control is started by the
IPDSTRT1 or IPDSTRT2 instruction.
• If an error occurs at the start of positioning control, the
previous value will be held.

CH1 current
value
CH1 current
value
• This register stores the current counter value of CH1 at
END processing.
• When the ICCNTRD1 instruction is executed, this register
is updated by the current value at that moment.
The current value is updated at END processing and by the
ICCNTRD1 instruction only when Normal Mode is set for
Operation Mode Setting (high-speed counter function
parameter). The range of a value that can be read is from -
2147483648 to 2147483647.
