The above parameters are valid with the value set in the flash ROM of the Motion module when the power ON
or the CPU module reset. Except for a part, the value is not fetched by turning the PLC READY signal [Y0] ON
from OFF. Therefore, write to the flash ROM after setting the value in the buffer memory to change.

Fetch cycle: Power supply ON
Set the optional buffer memory No.
Set this parameter as an even number.
0 to 16777214: Optional buffer memory
Fetch cycle: Power supply ON
Set the valid upper limit value for latch data at mark detection.
-2147483648 to 2147483647
Fetch cycle: Power supply ON, PLC READY signal [Y0] OFF to ON, or
latch data range change request
Set the valid lower limit value for latch data at mark detection.
-2147483648 to 2147483647
Fetch cycle: Power supply ON, PLC READY signal [Y0] OFF to ON, or
latch data range change request
Set the continuous detection mode or specified number of detection
mode.
0: Continuous detection mode
1 to 32: Specified number of detection mode (Set the number of
detections.)
-1 to -32: Ring buffer mode (Set the value that made the number of
buffers into negative value.)
Fetch cycle: Power supply ON or PLC READY signal [Y0] OFF to ON
Set the signal detection direction when TPR1 of the servo amplifier is
specified in "[Pr.800] Mark detection signal setting". Only the setting in
bit0 is valid.
