FUNCTION
Type of PID control
In AUTOMATIC mode, Inverter starts working
through ACC/DEC ramps equal to ACC
MANUAL/DEC MANUAL. When the
controlled variable reaches the set-point,
ACC/DEC are automatically set to the values
ACC AUTOMATIC / DEC AUTOMATIC.
This configuration remains till the stop of the
Inverter.
If the controlled variable does not reach the set-
point within PID ACC/DEC Delay seconds from
the start, ACC/DEC are set to the values ACC
AUTOMATIC/DEC AUTOMATIC
Type of velocity calculation.
The setting AIR has to be used in case the fluid
present in the pipe is air. Otherwise, you may use
the GENERIC setting. During velocity
calculation with the section AIR, you need to set
also the fluid temperature in °C, through the
parameter Fluid Temperature.
The calculation of the velocity with GENERIC
setting is base on the following formula::
v = k
P
where k = Velocity Constant (settable) and P is
the differential pressure in mmHH

If the MITOS VT6 AIR is enabled to send
commands to the inverter (Mode =
COMMAND) and it has the complete control of
the inverter (run-stop and frequency variation

(
)), the Command type parameter determines the
way the commands are sent
