As those with long memories might recall I run my 3HP CVA lathe via a
240-415 transformer and a 415volt 3 phase ACS 300 inverter. The transformer steps up the voltage and the inverter (a 7.5KW model) takes the single phase 415volt input and pumps out 3 phase 415volt. It's mild abuse of the inverter but I reckoned that a 2.2KW load on a 7.5KW inverter was a fair safety margin. The reason for this complex set up was to manage the current draw on start up via the inverter and not trip the circuit breaker.After some light work this afternoon I've now got a fault on the inverter. The message says "Unit Fault 12" which according to the manual is "Failure in reading analogue/digital input - consult dealer". I've no idea what the error description means. Should I get it fixed or bin it? If I do go for a repair where should I go?
Help and suggestions please.
