4.2.3 Specifying Forward/Reverse Action

(K7F-PIDA : Addresses 4, 5,

K4F-PIDA : Address 2)

1)Turns the corresponding bit Off(0) for forward action processing and On (1) for reverse action processing.

2)Default is forward action.

3)The following show the bit corresponding to each loop.

4.2.4 Specifying SET Data Enable/Disable

(K7F-PIDA : Addresses 6, 7,

K4F-PIDA : Address 3)

1)If a bit, corresponding to each loop, in Set Data specification area is turned On(1), then the PID processing is executed with new user-defined data due to loop enable/disable specification,

forward/reverse action specification, setting SV, setting M_MV, and change of P.I.D constants.

2) If the bit corresponding to each loop is not turned On(1), then the PID processing is executed not with the new user-defined data but with the previous Setting range.

3)The followings show the bit corresponding to each loop.
