MASTER priority
(for cascade serial / synchron only!)
Possible settings: ON - OFF
This parameter determines the alternation order when MASTER and BASIC Inverters are
used within one system. In such a case you have to select if either the MASTER or the BASIC
Inverters should be switched on first.
ON- all MASTER Inverters in the system are released (unless it is stopped by a failure or
manually) before the first BASIC Inverter gets released.
For example: Address 1-3.......MASTER Inverters
Address 4-8……BASIC Inverters
Switching order:
Adr 1

Adr 3

OFF- One MASTER (which is responsible for the controlling according the set value) is
running. With rising consumption all BASIC Inverters have to be released before any
other MASTER starts running.
