[Pr.800] Mark detection signal setting
Set the input signal for mark detection.
Setting Setting details
value
0 Invalid
1 to 4 External command signal (DI) of axis 1 to axis 4 (4-axis module)
1 to 8 External command signal (DI) of axis 1 to axis 8 (8-axis module)
1 to 16 External command signal (DI) of axis 1 to axis 16 (16-axis module)
301 to 304 Servo amplifier TPR1 of axis 1 to axis 4 (4-axis module)
301 to 308 Servo amplifier TPR1 of axis 1 to axis 8 (8-axis module)
301 to 316 Servo amplifier TPR1 of axis 1 to axis 16 (16-axis module)
If a value other than the above is set, the warning "Outside mark detection signal setting range" (warning code: 0D36H)
occurs and the target mark detection is not available.
• When carrying out the mark detection with an external signal command, 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".
• When carrying out the mark detection with TPR1 of the servo amplifier, assign TPR1 to CN3 of the servo amplifier.
Setting example
When "101: DOG signal of axis 1" is set in "[Pr.95] External command signal selection" and "8: External
command signal of axis 8 (DI)" is set in "[Pr.800] Mark detection signal setting" of axis 8, mark detection is
performed with the DOG signal of the servo amplifier connected to axis 1.
When the DOG signal is selected for use as the external command signal in "[Pr.95] External command signal
selection", the accuracy of the mark detection changes to the accuracy of the operation cycle.

[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.)

• When carrying out the mark detection with an external signal command with this parameter set, also set
"[Pr.95] External command signal selection".
• When carrying out the mark detection with TPR1 of the servo amplifier with this parameter set, also set
"[Pr.811] Mark detection signal detection direction setting". For the accuracy when using TPR1 of the servo
amplifier, refer to the manual of the servo amplifier.
