[Pr.800] Mark detection signal setting
Set the input signal for mark detection.
Setting value Setting details
0 Invalid
1 to 2 External command signal (DI) of axis 1 to axis 2 (RD77MS2)
1 to 4 External command signal (DI) of axis 1 to axis 4 (RD77MS4)
1 to 8 External command signal (DI) of axis 1 to axis 8 (RD77MS8)
1 to 16 External command signal (DI) of axis 1 to axis 16 (RD77MS16)
If a value other than the above is set, the warning "Outside mark detection signal setting range" (warning code: 0936H) occurs
and the target mark detection is not available.
Set "4: High speed input request" in "[Pr.42] External command function selection" and set "1: Validates an external
command." in "[Cd.8] External command valid".
[Pr.801] Mark detection signal compensation time
Compensate the input timing of the mark detection signal.
Set this parameter to compensate such as delay of sensor input. (Set a positive value to compensate for a delay.)
[Pr.802] Mark detection data type
Set the data that latched at mark detection.
The target data is latched by setting "0 to 12". Set the axis No. in "[Pr.803] Mark detection data axis No.".
Optional 2 word buffer memory is latched by setting "-1". Set the buffer memory No. in "[Pr.804] Mark detection data buffer
memory No.".
Setting value Data name
0 Current feed value
1 Machine feed value
2 Real current value
3 Servo input axis current value
6 Synchronous encoder axis current value
7 Synchronous encoder axis current value per cycle
8 Current value after composite main shaft gear
9 Current value per cycle after main shaft gear
10 Current value per cycle after auxiliary shaft gear
11 Cam axis current value per cycle
12 Cam axis current value per cycle (Real position)
-1 Optional 2 words buffer memory
If a value other than the above is set, the warning "Outside mark detection data type setting range" (warning code: 0937H)
occurs and the target mark detection is not available.
