Cycle End Detection: Sequence Output Signal (Reference Value 21) - Fuji Electric ALPHA7 User Manual

CHAPTER 2 WIRING

Cycle end detection: Sequence output signal (Reference value 21)

Add a cycle end to positioning data to check if the data position is reached. PA2_41 (sequential start
selection) must be set at "1" (enable). Change PA2_40 (internal positioning data selection) to "1"
(enable).
This signal is enabled only for LS type.

 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 the cycle end detection to IQ area (sequence output terminal), specify the corresponding
value ("21") to the output terminal function setting parameter.
