Caution:
(1) Set the period taken from entering position No. to turning the PWRT ON to 6ms or longer. In
spite of 6ms timer process in the PLC, commands may be input to the controller concurrently
to cause writing to another position. Take the scanning time in the PLC into account, set a
period as 2 to 4 times as the scanning time.
(2) Turning the PWRT signal ON in the state in which home return is not completed (the HEND
signal is set to ON) causes alarm 093 “PWRT signal detected before completion of home
return” to occur.
(3) Turning PWRT signal OFF before turning WEND signal ON disturbs the proper data writing.

data, take the following actions:
1) PC software ···· Left-click the button.
