PID automatic switchover control (Pr. 127)
●
The system can be started up more quickly by starting up without PID control activated.
●
When Pr. 127 "PID control automatic switchover frequency" is set, the startup is made without PID
control until the output frequency reaches the Pr. 127 setting. Once the PID control starts, the PID
control is continued even if the output frequency drops to Pr. 127 setting or lower.
Selection of action at a communication error and SLEEP function stop selection
(FUP signal, FDN signal,Y48 signal, Pr. 554)
●
Using Pr. 554 "PID signal operation selection", set the action 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").
●
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.
