POINT
The above parameters are valid with the value set in the flash ROM of the Simple
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 ON from OFF.
Therefore, write to the flash ROM after setting the value in the buffer memory to
change.
[Pr.800] Mark detection signal setting
Set the input signal for mark detection.
0 : Invalid
1 to 4 : External command signal (DI) of axis 1 to axis 4 (at 4-axis module use)
1 to 8 : External command signal (DI) of axis 1 to axis 8 (at 8-axis module use)
1 to 16 : External command signal (DI) of axis 1 to axis 16 (at 16-axis module
use)
If a value other than the above is set, the warning "Outside mark detection signal
setting range" (warning code: 130) 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.".
0 : Feed current value
1 : Feed machine 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: 131) occurs and the target mark detection is not
available.
