Operation at fast logic start
The fast logic function operates in the safe operation mode, and operation is stopped (output OFF) except in the fast logic
interlock state and the safe operation mode.
The operation when the fast logic pattern setting is Pattern 2 is shown below.
Operating procedure
1.
Turn off and on the safety output enable signals (SA\Y0, SA\Y1).
2.
Turn on and off the fast logic initial request flag (SA\Y8).
3.
Check whether the fast logic initial completion flag (SA\XD) is on, and then turn on and off the fast logic start flag
(SA\Y9).
4.
Turn on the input signals that satisfy the conditions of the logic pattern.
5.
The output signals (Y0, Y1) turn on.
Executed by the program
(1) Even when the fast logic initial request flag (SA\Y8) and fast logic start flag (SA\Y9) are operated in other than the safe operation mode, the fast logic
function is not enabled.
(2) Turning on and off the fast logic initial request flag (SA\Y8) in the safety drive mode causes fast logic initial processing to be performed. When initial
processing is completed, the fast logic initial completion flag (SA\XD) turns ON.
(3) When the fast logic start flag (SA\Y9) is turned off and on while the fast logic initial completion flag (SA\XD) is on, fast logic READY (SA\XC) turns on, fast
logic initial completion flag (SA\XD) turns off, and the fast logic function is enabled.
(4) When the fast logic interlock state is entered, fast logic READY (SA\XC) turns off and the fast logic function stops.
(5) When a mode other than safe operation mode is entered, fast logic READY (SA\XC) turns off and the fast logic function stops.
