Radi se o inverteru L2000,kod ukljuèivanja izbacuje gre¹ku E14,moguæe resetirati al kod startanja motora izbacuje gre¹ku E3.(kao preoptereæenje motora) Motor je 100 posto ispravan,inverter se ne mo¾e postaviti na tvornièke postavke. Inaèe je ovo licenca Hitachi invertera serije L200.
U inverter si unio parametre motora, broj polova i nazivnu struju? Vrijeme ubrzavanja (akceleracija) nije postavljeno na premalu vrijednost? f
E14: Ground fault protection The inverter is protected by detection of ground faults between the drive output and the motor at power on. Protection is for the inverter only and not for humans.
E3: Overcurrent protection at acceleration When the output of the inverter is short circuited, the motor is locked, or a heavy load is suddenly applied, and the inverter output current exceeds a predetermined level, the inverter is shut off.
Uglavnom, ukoliko je sigurno sve u redu sa ozicenjem i motorom, frekventni otisao u vjecna lovista... Na kakvom je stroju taj frekventi?
tako sam i ja zakljuèio da mu nema spasa :( inverter je pokretao ventilator 3 kW
