Parameter list of pressure and flow command limit
The minimum pressure and flow command limitation (F4.21 and F4.23) works
all the time, independently to any control bit. That means if the setting pres‐
sure or flow command is lower than [F4.21] or [F4.23], it will be limited to
[F4.21] or [F4.23] without any error / warning message.
The maximum pressure and flow command limitation can be activated via
bit2 of F4.00. This function will check whether the pressure or flow command
given by customer exceeds the limitation set in [F4.22] and [F4.24]. If a given
command exceeds its limitation, the effective command value will be limited
to the maximum limit, and a warning signal will be raised.
