Fault Legend Description
1758A 95626 30090 OPE10 Fault V/F Ptrn Setting. V/f data setting
fault. Yes Yes Yes Minor Major Occurs when the custom V/f pattern
does not meet the following criteria:
inverter parameters E1-04 > E1-06 >
E1-07 > E1-09.
1758B 95627 30091 OPE11 Fault CarrFrq/ON-Delay. Carrier
frequency parameter(s) set out of
range. Yes Yes Yes Minor Major Occurs when the carrier frequency
inverter parameters are set as
follows: C6-01 > 5 kHz and C6-02 <

175F8 95736 30200 Alm:Undervoltage UV – Main circuit undervoltage.
Occurs 2 seconds after detection of
low voltage. Detection levels:
190VDC for 230V rated unit;
380VDC for 460V rated unit;
546VDC for 600V rated unit. Yes Yes Yes Minor Minor Check input AC supply. Possibility
of erroneous operation due to noise:
remove noise source by connecting
surge suppressor to relay and
magnetic contactor coils; provide line
filter to remove noise on input power
line. Possibility of gate drive PCB is
faulty. Note: alarm is declared only if
drive is NOT in Run mode.
