OFF
Cycle end detection: Sequence output signal (Reference value 21)
This signal is turned on after the cycle end position is reached if the cycle end is assigned to the
positioning data. PA2_41 (sequential start selection) must be set at “1” (enable). Change PA2_40
(internal positioning data selection) to “1” (enable).
 Function
Starting at the positioning data at an arbitrary address, execute positioning data with merely the
start positioning signal sequentially until positioning data including the “CEND” status is reached.
Follow the procedure below to execute sequential start.
(1) Designate the first positioning data number and issue the start positioning signal to start the
positioning motion.
(2) Turn all positioning data addresses off and issue the start positioning signal. The motion
starts with the next positioning data.
(3) Step (2) is repeated until the positioning data including “CEND” is reached
(4) After positioning motions are completed up to the positioning data including “CEND,” the
cycle end detection signal is turned on at the same timing as the in-position signal.
(5) You can supply the start positioning signal with all addresses turned off to repeat the above
steps (1) through (4).
 Parameter setting
To assign cycle end detection to a sequence output terminal, enter the corresponding value (“21”)
to the output terminal function setting parameter.
 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
