Meaning
• 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 watchdog 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".
*1 Range: 0 to 2147483647 pulses
• 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.
• 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.
This register stores each status of CH1.
