Selection of the operation when a PID measured value
error is detected
• The operation when the PID measured value exceeds the upper or lower limit can be selected.

Operation selection and sleep function stop selection when a value
error is detected (FUP signal, FDN signal, Y48 signal, Pr.554)
• Set the operation when the measured value input exceeds the upper limit (Pr.131 PID upper limit) or lower limit
(Pr.132 PID lower limit), or when the deviation input exceeds the permissible value (Pr.553 PID deviation limit)
in Pr.554 PID signal operation selection.
• Set the time from when the measured value input exceeds the Pr.131 or Pr.132 setting until the FUP or FDN
signal is output in Pr.1370 Detection time for PID limiting operation.
• Set Pr.554 to select the operation when the FUP/FDN or Y48 signal is output, and the operation when the sleep
function is activated.


When each of Pr.131, Pr.132 and Pr.553 settings corresponding to each of the FUP, FDN and Y48 signals is "9999" (no function),
signal output and protective function are not available.

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.

Description
The operation when the upper or lower limit for a
measured value input is detected or when a limit for the
deviation is detected can be selected. The operation for
PID output suspension function can be also selected.
Set the time from when the measured value input exceeds
the Pr.131 or Pr.132 setting until the FUP or FDN signal is
output.
