to communicate 2 inverters

[Davimont]

a good day to all.
Unfortunately I do not know anything about inverter and therefore my question will be very generic. the purpose is to know if in theory it is possible to do a certain thing.
I have a system where I press air through two extractors connected to an inverter and subsequently reimposed with another fan connected to another inverter (currently I do not know the precise models).

the basic concept is that if I extract for example (the values are entirely random) 40,000mc/h I must reimpose 38,000mc/h to have a certain depression inside. everything must be modulated according to the need of the moment.


Currently the adjustments are made to handle through the two respective potentiometers, so if the operator needs less suction lowers to the eye the first potentiometer and then tries to balance the second always to the eye.

from here my question if it is possible that the second inverter can receive a signal from the first for auto adjust.
I am sure 99% of yes but a colleague says otherwise.
can be that some inverters allow this thing and others do not?
thank you to those who want to answer me.

by means of a mini plc it is possible to program the two inverters and to make them dialogue with the addition if needed, of probes and sensors.

So, in part, my partner is right? in the current state it is not possible to make to work an inverter as master and one as slave? do I have to add a plc?
the system does not need a prompt control of the flow and therefore there are no probes or sensors. It's like the car fan, if I'm hot step by speed 2 to speed 3 without wanting to know how much air travels
I thought we could read to the second inverter the state of the first and adapt accordingly.
a plc would have me wasted for something like that but it would have been ideal if thought already in the project phase.
thanks mechanicalmg for the answer.

some inverters have the possibility to take the speed reference and manage it, so let's say that some well made inverters can manage a signal and consequently adjust.
you should take the manual of your inverter and watch what you can do.

Thank you again. I try to get the installed inverter models and I study them.
