• For the Y229 and Y230 signals, assign the functions to output terminals using the Pr.190 to Pr.196 (Output terminal
function selection).
• To monitor the input pressure, set "69" in the monitor selection parameters. (0.1% increments)
NOTE
• When the control switches between the first PID control and second PID control while the set point is changed by the
Pr.1380 setting value or while the Y229/Y230 signal is output, the set point returns to its original value or the signal turns
OFF, and the detection restarts.
• When the PID input pressure control function and the PID upper/lower limit pre-warning function are used simultaneously,
each function may change the set point. When the set point change is attempted by both functions, the change by the PID
input pressure control function has priority.
• When the PID input pressure control function and the PID sleep boost function are used simultaneously, each function may
change the set point. When the set point change is attempted by both functions, the change by the PID input pressure
control function has priority. (The sleep state is established without applying the set point change by the PID sleep boost
function.)
