How to use mark detection function
An example for mark detection using the DOG signal of the MR-J5(W)-G is shown below.
The mark detection target is axis 1 real current value, and the all range is detected in continuous detection mode.
• Allocate the input signal to the external signal of the slave of axis 2, and set the "high speed input request" for mark
detection.

• Set the following mark detection setting parameters. The optional mark detection setting No. can be set.
k: Mark detection setting No. - 1
Setting item
[Pr.800] Mark detection signal setting
[Pr.801] Mark detection signal

[Pr.802] Mark detection data type
[Pr.803] Mark detection data axis No.
[Pr.805] Latch data range upper limit

[Pr.806] Latch data range lower limit

[Pr.807] Mark detection mode setting
• Turn the power supply OFF or reset of the CPU module to validate the setting parameters.
• The mark detection starts by setting "1: Validates an external command." in "[Cd.8] External command valid" of axis 2 with
the program. Refer to "[Md.800] Number of mark detection" or "[Md.801] Mark detection data storage area (1 to 32)" of the
set detection setting No. for the number of mark detections and mark detection data.

Setting Setting details/setting value
value
4 Set "4: High speed input request" as the function used in the external
command signal of axis 2.
102 Set "102: DOG signal of axis 2" to the external command signal of axis 2.
Setting Setting details/setting value
value
2 Set "2: Axis 2" to the external input signal for mark detection.
0 Set "0: (No compensation)" to the compensation time such as delay of
sensor.
2 Set "2: Real current value" to the target data for mark detection.
1 Set "1: Axis 1" to the axis No. of target data for mark detection.
0 Set "0" to the valid upper limit value for latch data at mark detection. (Mark
detection for all range is executed by setting the same value as lower limit
value.)
0 Set "0" to the valid lower limit value for latch data at mark detection. (Mark
detection for all range is executed by setting the same value as upper limit
value.)
0 Set "0: Continuous detection mode" to the mark detection mode.
