PID deviation output – If PID deviation "ε" exceeds the value in C044, output signal
configured as 04 (OD) is activated.
PID feedback comparison output – If PID feedback is out of the range between C052
and C053 output signal configured as 31 (FBV) is activated.
PID scaling – When PID scale parameter (A075) is set, following variables are scaled.
(monitored) = (variable) ×（A075）

PID Sleep Function
The inverter shuts off the output when the PID output becomes less than the specified
value (A156) in case of PID is set enabled, or shuts off when the frequency command
becomes less than the specified value in case of PID is set disabled. And if the PID
output or frequency command exceeds the specified value (A156) for a specified period
(A157), inverter automatically restarts the operation. This is the PID sleep function.
PID Sleep function is always enabled, even the PID function is disabled.
