Tab. 7-23: 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 pressure 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 maxi-
mum limit, and a warning signal will be raised.
