Description of I/O Signals
2
 Relevant description
The cycle end detection signal is not output if sequential start cannot be executed.

If the servo-on signal is turned off

If the pulse ratio is enabled or a homing cycle is executed during sequential operation

If +OT or -OT is detected or if software OT is detected
Neither positioning cancel nor pause gives effects on cycle end detection.
When positioning data number 15 is reached during sequential operation, the cycle end process is
executed.
If data continuation designation is included in positioning data, operation starts at the next data
having no data continuation designation.
Homing completion: Sequence output signal (Reference value 22)
This signal is turned on after the homing motion is finished.
 Function
This signal is turned on after the homing motion is normally finished. It remains turned on if the
feedback position is within PA2_17 (home position detection range) around PA2_16 (home position
after homing completion).
The signal is always turned on after homing if PA2_17 (home position detection range) is "0" or the
maximum value.
The home position is the stopping point after a homing motion is finished, or a position at which
position preset is executed. It does not mean the "0" position.
 Parameter setting
To assign the homing completion to a sequence output terminal, specify the corresponding value
("22") to the output terminal function setting parameter.
