10.4 Inverter Parameters (ID 51 – 550)
;60; ;Input Source (AC : 0, DC : 100); ;0; ;%;
x Record of priority source
x 0 –> Priority feed from ACin (converter AC/AC - AC/AC mode), Default setting
x 100 –> Priority feed from DC (converter DC/AC - On Line mode)
;61; ;AC
in
Mode (0 : normal, 1 : Safe); ;0; ; ;
x Opens the AC
in
inlet relay
x 0 –> Normal running in AC/AC mode, Default setting
x 1 –> ACin inlet relay is open and so the system is insulated from the Mains
;62; ;Walk-in Mode (0 : No, 1 : Yes) ; ;1; ; ;
x Walk-in mode allows a progressive comeback, slowly removing DC power while slowly
increasing AC power
x 0 –> no progressive switching
x 1 –> progressive switching at 10% per second
;70; ;Number of phases ; ;3; ; ;
x Record of number of phases : 1 (Single phase), 2 (2 phase), 3 (3 phase)
x Range: 0 - 8, Default: 1
;71; ;Mode (0 star; 1 Delta) ; ;1; ; ;
x Record of the protection for working on Delta load
x The mode, star or delta, allows configuration of automatic protection when the load is a
delta connection (an engine for instance). This protects the load when 1 phase is lost. The
protection consists of switching off all inverters.
x 0 –> no delta load protection, Default setting
x 1 –> Delta load protection available
;75; ;Free running Frequency ; ;50.0; ;Hz;
x Record of the Inverters system frequency, 50 or 60 (default)
