FR-F800 5 - 365
When each of Pr. 131, Pr. 132 and Pr. 553 corresponding to each of the FUP, FDN and Y48 signals is
set to "9999" (function not activated), signal output and protective function are disabled.
At the same time with the signal output, the protective function (E.PID) is activated.
At the same time with the signal output, deceleration is performed using the normal deceleration
time. After the deceleration stop, the protective function (E.PID) is activated.
At the same time with the signal output, deceleration is performed using the normal deceleration
time. When the measured value returns to normal, operation can be restarted.

Example chart
Protective function (E.PID) activation at the same time with the signal output (Pr. 554 = "1, 3, 11,
or 13") / Protective function activation after the deceleration stop (Pr. 554 = "4, 6, 14, or 16") (reverse
action)

Deceleration stop (restart) at the signal output (Pr. 554 = "5, 7, 15, or 17") (reverse action)
