Relevant term explanation:
Terminal Xi: Refers to any of terminal X1, X2, X3, X4, X5, X6 or X7, also called terminal X.
Terminal Yi: Refers to terminal Y1, Y2 or relay also called terminal Y.
Terminal function enabled: Means that terminal Xi has set the function under description. And P7.25
adopts the leave-factory value, the terminal is closed; when the P7.25 adopts the non-leave-factory value,
the terminal is open.
Terminal function disabled: Means that terminal Xi has not set the function under description; or it has set
the function, but when P7.25 adopts the leave-factory value, the terminal is open; or when the P7.25
adopts the non-leave-factory value, the terminal is closed.
The leave-factory setting of terminal Xi (i=1~7) is no function (function code set as 99).
0: Terminal jog forward input
1: Terminal jog reverse input
2: Terminal forward run input (FWD)
